A Parent’s Guide to Working From Home, During a Global Pandemic, Without Going Insane

Though I usually enjoy working from Viget’s lovely Boulder office, during quarantine I am now working from home while simultaneously parenting my 3-year-old daughter Audrey. My husband works in healthcare and though he is not on the front lines battling COVID-19, he is still an essential worker and as such leaves our home to work every day.

Some working/parenting days are great! I somehow get my tasks accomplished, my kid is happy, and we spend some quality time together.

And some days are awful. I have to ignore my daughter having a meltdown and try to focus on meetings, and I wish I wasn’t in this situation at all. Most days are somewhere in the middle; I’m just doing my best to get by.

I’ve seen enough working parent memes and cries for help on social media to know that I’m not alone. There are many parents out there who now get to experience the stress and anxiety of living through a global pandemic while simultaneously navigating ways to stay productive while working from home and being an effective parent. Fun isn’t it?

I’m not an expert on the matter, but I have found a few small things that are making me feel a bit more sane. I hope sharing them will make someone else’s life easier too.

Truths to Accept

First, let’s acknowledge some truths about this new situation we find ourselves in:

Truth 1: We’ve lost something.

Parents have lost more than daycare and schools during this epidemic. We’ve lost any time that we had for ourselves, and that was really valuable. We no longer have small moments in the day to catch up on our personal lives. I no longer have a commute to separate my work duties from my mom duties, or catch up with my friends, or just be quiet.

Truth 2: We’re human.

The reason you can’t be a great employee and a great parent and a great friend and a great partner or spouse all day every day isn’t because you’re doing a bad job, it’s because being constantly wonderful in all aspects of your life is impossible. Pick one or two of those things a day to focus on.

Truth 3: We’re all doing our best.

This is the most important part of this article. Be kind to yourselves. This isn’t easy, and putting so much pressure on yourself that you break isn’t going to make it any easier.

Work from Home Goals

Now that we’ve accepted some truths about our current situation, let’s set some goals.

Goal 1: Do Good Work

At Viget, and wherever you work, with kids or without we all want to make sure that the quality of our work stays up throughout the pandemic and that we can continue to be reliable team members and employees to the best of our abilities.

Goal 2: Stay Sane

We need to figure out ways to do this without sacrificing ourselves entirely. For me, this means fitting my work into normal work hours as much as possible so that I can still have some downtime in the evenings.

Goal 3: Make This Sustainable

None of us knows how long this will last but we may as well begin mentally preparing for a long haul.

Work from Home Rules

Now, there are some great Work from Home Rules that apply to everyone with or without kids. My coworker Paul Koch shared these with the Viget team a Jeremy Bearimy ago and I agree this is also the foundation for working from home with kids.

  1. When you’re in a remote meeting, minimize other windows to stay focused
  2. Set a schedule and avoid chores*
  3. Take breaks away from the screen
  4. Plan your workday on the calendar+
  5. Be mindful of Slack and social media as a distraction
  6. Use timers+
  7. Keep your work area separate from where you relax
  8. Pretend that you’re still WFW
  9. Experiment and figure out what works for you

In the improv spirit I say “Yes, AND….” to these tips. And so, here are my adjusted rules for WFH while kiddos around: These have both been really solid tools for me, so let’s dig in.

Daily flexible schedule for kids

Day Planning: Calendars and Timers

A few small tweaks and adjustments make this even more doable for me and my 3-year-old. First- I don’t avoid chores entirely. If I’m going up and down the stairs all day anyway I might as well throw in a load of laundry while I’m at it. The more I can get done during the day means a greater chance of some down time in the evening.

Each morning I plan my day and Audrey’s day:

My Work Day:

Audrey's Day

Identify times of day you are more likely to be focus and protect them. For me, I know I have a block of time from 5-7a before Audrey wakes up and again during “nap time” from 1-3p.I built a construction paper “schedule” that we update and reorganize daily. We make the schedule together each day. She feels ownership over it and she gets to be the one who tells me what we do next.
Look at your calendar first thing and make adjustments either in your plans or move meetings if you have to.I’m strategic about screen time- I try to schedule it when I have meetings. It also helps to schedule a physical activity before screen time as she is less likely to get bored.
Make goals for your day: Tackle time sensitive tasks first. Take care of things that either your co-workers or clients are waiting on from you first, this will help your day be a lot less stressful. Non-time sensitive tasks come next- these can be done at any time of day.We always include “nap time” even though she rarely naps anymore. This is mostly a time for us both to be alone.

When we make the schedule together it also helps me understand her favorite parts of the day and reminds me to include them.

Once our days are planned, I also use timers to help keep the structure of the day. (I bought a great alarm clock for kids on Amazon that turns colors to signal bedtime and quiet time. It’s been hugely worth it for me.)

Timers for Me:

Timers for Audrey:

More than ever, I rely on a time tracking timer. At Viget we use Harvest to track time, and it has a handy built in timer, but there are many apps or online tools that could help you keep track of your time as well.Audrey knows what time she can come out of her room in the morning. If she wakes up before the light is green she plays quietly in her room.
I need a timer because the days and hours are bleeding together- without tracking as I go it would be really hard for me to remember when I worked on certain projects or know for certain if I gave Viget enough time for the day.She knows how long “nap time” is in the afternoon.
Starting and stopping the timer helps me turn on and off “work mode”, which is a helpful sanity bonus.Perhaps best of all I am not the bad guy! “Sorry honey, the light isn’t green yet and there really isn’t anything mommy can do about it” is my new favorite way to ensure we both get some quiet time.

Work from Home Rules: Updated for Parents

Finally, I have a few more Work from Home Rules for parents to add to the list:

  1. Minimize other windows in remote meetings
  2. Set a schedule and fit in some chores if time allows
  3. Take breaks away from the screen
  4. Schedule both your and your kids’ days
  5. Be mindful of Slack and social media as a distraction
  6. Use timers to track your own time and help your kids understand the day
  7. Keep your work area separate from where you relax
  8. Pretend that you’re still WFW
  9. Experiment and figure out what works for you
  10. Be prepared with a few activities
    • Each morning, have just ONE thing ready to go. This can be a worksheet you printed out, a coloring station setup, a new bag of kinetic sand you just got delivered from Amazon, a kids dance video on YouTube or an iPad game. Recently I started enlisting my mom to read stories on Facetime. The activity doesn’t have to be new each day but (especially for young kids) it has to be handy for you to start up quickly if your schedule changes
  11. Clearly communicate your availability with your team and project PMs
    • Life happens. Some days are going to be hard. Whatever you do, don’t burn yourself out or leave your team hanging. If you need to move a meeting or take a day off, communicate that as early and as clearly as you can.
  12. Take PTO if you can
    • None of us are superheroes. If you’re feeling overwhelmed- take a look at the next few days and figure out which one makes the most sense for you to take a break.
  13. Take breaks to be alone without doing a task
    • Work and family responsibilities have blended together, there’s almost no room for being alone. If you can find some precious alone time don’t use it to fold laundry or clean the bathroom. Just zone out. I think we all really need this.

Last but not least, enjoy your time at home if you can. This is an unusual circumstance and even though it’s really hard, there are parts that are really great too.

If you have some great WFH tips we’d love to hear about them in the comments!

Global Gitignore Files Are Cool and So Are You

Setting it up

First, here's the config setup you need to even allow for such a radical concept.

  1. Define the global gitignore file as a global Git configuration:

    git config --global core.excludesfile ~/.gitignore
    

    If you're on OSX, this command will add the following config lines in your ~/.gitconfig file.

    [core]
      excludesfile = /Users/triplegirldad/.gitignore
    
  2. Load that ~/.gitignore file up with whatever you want. It probably doesn't exist as a file yet so you might have to create it first.

Harnessing its incredible power

There are only two lines in my global gitignore file and they are both fairly useful pretty much all the time.

$ cat ~/.gitignore
TODO.md
playground

This 2 line file means that no matter where I am, what project I'm working on, where in the project I'm doing so, I have an easy space to stash notes, thoughts, in progress ideas, spikes, etc.

TODO.md

More often than not, I'm fiddling around with a TODO.md file. Something about writing markdown in your familiar text editor speaks to my soul. It's quick, it's easy, you have all the text editing tricks available to you, and it never does anything you wouldn't expect (looking at you auto-markdown-formatting editors). I use one or two # for headings, I use nested lists, and I ask for nothing more. Nothing more than more TODO.md files that is!

In practice I tend to just have one TODO.md file per project, right at the top, ready to pull up in a few keystrokes. Which I do often. I pull this doc up if:

  • I'm in a meeting and I just said "oh yeah that's a small thing, I'll knock it out this afternoon".
  • I'm halfway through some feature development and realize I want to make a sweeping refactor elsewhere. Toss some thoughts in the doc, and then get back to the task at hand.
  • It's the end of the day and I have to switch my brain into "feed small children" mode, thus obliterating everything work-related from my short term memory. When I open things up the next day and know exactly what the next thing to dive into was.
  • I'm preparing for a big enough refactor and I can't hold it all in my brain at once. What I'd give to have an interactive 3D playground for brain thoughts, but in the meantime a 2D text file isn't a terrible way to plan out dev work.

playground

Sometimes you need more than some human words in a markdown file to move an idea along. This is where my playground directory comes in. I can load this directory up with code that's related to a given project and keep it out of the git history. Because who doesn't like a place to play around.

I find that this directory is more useful for long running maintenance projects over fast moving greenfield ones. On the maintenance projects, I tend to find myself assembling a pile of scripts and experiments for various situations:

  • The client requests a one-time obscure data export. Whip up some CSV generation code and save that code in the playground directory.
  • The client requests a different obscure data export. Pull up the last time you did something vaguely similar and save yourself the startup time.
  • A batch of data needs to be imported just once. Might as well stash that in the chance that "just once" is actually "just a few times".
  • Kicking the tires on an integration with a third party service.

Some of these playground files end up being useful more times than I can count (eg: the ever-changing user_export.rb script). Some items get promoted into application code, which is always fun. But most files here serve their purpose and then wither away. And that's fine. It's a playground, anything goes.

Wrapping up

Having a personal space for project-specific notes and code has been helpful to me over the years as a developer on multiple projects. If you have your own organizational trick, or just want to brag about how you memorize everything without any markdown files, let me know in the comments below!

Intuition, Creative Freedom & Doing What You Love with Chris Ballew

Today’s episode is going to rock your world … pun fully intended because today’s guest is an actual rock star. You may remember a band called Presidents of the United States of America. They took the world by storm in 1995 with their self titled album, Presidents of the United States of America playing songs like Lump and Peaches. Yes, that’s right. My guest today is frontman Chris Ballew. Chris and I have been friends for years, including collaborating on a music video together and at least one live performance (gotta listen to find out ;). Of course we get into his musical journey, a meteoric rise to success, and then realizing something was missing. We take some deep dives into Chris’ creative process, including his method for capturing his small bits and later using those to write new works, including his new project Casper Babypants. In this episode: Consider what kind of artist you are and how you relate to other artists. For years Chris played in bands, but what he learned about himself is his work is actually solo. Don’t censor yourself while you’re creating. Get it out, no matter how crazy or ridiculous or unusual and then […]

A Parent’s Guide to Working From Home, During a Global Pandemic, Without Going Insane

Though I usually enjoy working from Viget’s lovely Boulder office, during quarantine I am now working from home while simultaneously parenting my 3-year-old daughter Audrey. My husband works in healthcare and though he is not on the front lines battling COVID-19, he is still an essential worker and as such leaves our home to work every day.

Some working/parenting days are great! I somehow get my tasks accomplished, my kid is happy, and we spend some quality time together.

And some days are awful. I have to ignore my daughter having a meltdown and try to focus on meetings, and I wish I wasn’t in this situation at all. Most days are somewhere in the middle; I’m just doing my best to get by.

I’ve seen enough working parent memes and cries for help on social media to know that I’m not alone. There are many parents out there who now get to experience the stress and anxiety of living through a global pandemic while simultaneously navigating ways to stay productive while working from home and being an effective parent. Fun isn’t it?

I’m not an expert on the matter, but I have found a few small things that are making me feel a bit more sane. I hope sharing them will make someone else’s life easier too.

Truths to Accept

First, let’s acknowledge some truths about this new situation we find ourselves in:

Truth 1: We’ve lost something.

Parents have lost more than daycare and schools during this epidemic. We’ve lost any time that we had for ourselves, and that was really valuable. We no longer have small moments in the day to catch up on our personal lives. I no longer have a commute to separate my work duties from my mom duties, or catch up with my friends, or just be quiet.

Truth 2: We’re human.

The reason you can’t be a great employee and a great parent and a great friend and a great partner or spouse all day every day isn’t because you’re doing a bad job, it’s because being constantly wonderful in all aspects of your life is impossible. Pick one or two of those things a day to focus on.

Truth 3: We’re all doing our best.

This is the most important part of this article. Be kind to yourselves. This isn’t easy, and putting so much pressure on yourself that you break isn’t going to make it any easier.

Work from Home Goals

Now that we’ve accepted some truths about our current situation, let’s set some goals.

Goal 1: Do Good Work

At Viget, and wherever you work, with kids or without we all want to make sure that the quality of our work stays up throughout the pandemic and that we can continue to be reliable team members and employees to the best of our abilities.

Goal 2: Stay Sane

We need to figure out ways to do this without sacrificing ourselves entirely. For me, this means fitting my work into normal work hours as much as possible so that I can still have some downtime in the evenings.

Goal 3: Make This Sustainable

None of us knows how long this will last but we may as well begin mentally preparing for a long haul.

Work from Home Rules

Now, there are some great Work from Home Rules that apply to everyone with or without kids. My coworker Paul Koch shared these with the Viget team a Jeremy Bearimy ago and I agree this is also the foundation for working from home with kids.

  1. When you’re in a remote meeting, minimize other windows to stay focused
  2. Set a schedule and avoid chores*
  3. Take breaks away from the screen
  4. Plan your workday on the calendar+
  5. Be mindful of Slack and social media as a distraction
  6. Use timers+
  7. Keep your work area separate from where you relax
  8. Pretend that you’re still WFW
  9. Experiment and figure out what works for you

In the improv spirit I say “Yes, AND….” to these tips. And so, here are my adjusted rules for WFH while kiddos around: These have both been really solid tools for me, so let’s dig in.

Daily flexible schedule for kids

Day Planning: Calendars and Timers

A few small tweaks and adjustments make this even more doable for me and my 3-year-old. First- I don’t avoid chores entirely. If I’m going up and down the stairs all day anyway I might as well throw in a load of laundry while I’m at it. The more I can get done during the day means a greater chance of some down time in the evening.

Each morning I plan my day and Audrey’s day:

My Work Day:

Audrey's Day

Identify times of day you are more likely to be focus and protect them. For me, I know I have a block of time from 5-7a before Audrey wakes up and again during “nap time” from 1-3p.I built a construction paper “schedule” that we update and reorganize daily. We make the schedule together each day. She feels ownership over it and she gets to be the one who tells me what we do next.
Look at your calendar first thing and make adjustments either in your plans or move meetings if you have to.I’m strategic about screen time- I try to schedule it when I have meetings. It also helps to schedule a physical activity before screen time as she is less likely to get bored.
Make goals for your day: Tackle time sensitive tasks first. Take care of things that either your co-workers or clients are waiting on from you first, this will help your day be a lot less stressful. Non-time sensitive tasks come next- these can be done at any time of day.We always include “nap time” even though she rarely naps anymore. This is mostly a time for us both to be alone.

When we make the schedule together it also helps me understand her favorite parts of the day and reminds me to include them.

Once our days are planned, I also use timers to help keep the structure of the day. (I bought a great alarm clock for kids on Amazon that turns colors to signal bedtime and quiet time. It’s been hugely worth it for me.)

Timers for Me:

Timers for Audrey:

More than ever, I rely on a time tracking timer. At Viget we use Harvest to track time, and it has a handy built in timer, but there are many apps or online tools that could help you keep track of your time as well.Audrey knows what time she can come out of her room in the morning. If she wakes up before the light is green she plays quietly in her room.
I need a timer because the days and hours are bleeding together- without tracking as I go it would be really hard for me to remember when I worked on certain projects or know for certain if I gave Viget enough time for the day.She knows how long “nap time” is in the afternoon.
Starting and stopping the timer helps me turn on and off “work mode”, which is a helpful sanity bonus.Perhaps best of all I am not the bad guy! “Sorry honey, the light isn’t green yet and there really isn’t anything mommy can do about it” is my new favorite way to ensure we both get some quiet time.

Work from Home Rules: Updated for Parents

Finally, I have a few more Work from Home Rules for parents to add to the list:

  1. Minimize other windows in remote meetings
  2. Set a schedule and fit in some chores if time allows
  3. Take breaks away from the screen
  4. Schedule both your and your kids’ days
  5. Be mindful of Slack and social media as a distraction
  6. Use timers to track your own time and help your kids understand the day
  7. Keep your work area separate from where you relax
  8. Pretend that you’re still WFW
  9. Experiment and figure out what works for you
  10. Be prepared with a few activities
    • Each morning, have just ONE thing ready to go. This can be a worksheet you printed out, a coloring station setup, a new bag of kinetic sand you just got delivered from Amazon, a kids dance video on YouTube or an iPad game. Recently I started enlisting my mom to read stories on Facetime. The activity doesn’t have to be new each day but (especially for young kids) it has to be handy for you to start up quickly if your schedule changes
  11. Clearly communicate your availability with your team and project PMs
    • Life happens. Some days are going to be hard. Whatever you do, don’t burn yourself out or leave your team hanging. If you need to move a meeting or take a day off, communicate that as early and as clearly as you can.
  12. Take PTO if you can
    • None of us are superheroes. If you’re feeling overwhelmed- take a look at the next few days and figure out which one makes the most sense for you to take a break.
  13. Take breaks to be alone without doing a task
    • Work and family responsibilities have blended together, there’s almost no room for being alone. If you can find some precious alone time don’t use it to fold laundry or clean the bathroom. Just zone out. I think we all really need this.

Last but not least, enjoy your time at home if you can. This is an unusual circumstance and even though it’s really hard, there are parts that are really great too.

If you have some great WFH tips we’d love to hear about them in the comments!

Global Gitignore Files Are Cool and So Are You

Setting it up

First, here's the config setup you need to even allow for such a radical concept.

  1. Define the global gitignore file as a global Git configuration:

    git config --global core.excludesfile ~/.gitignore
    

    If you're on OSX, this command will add the following config lines in your ~/.gitconfig file.

    [core]
      excludesfile = /Users/triplegirldad/.gitignore
    
  2. Load that ~/.gitignore file up with whatever you want. It probably doesn't exist as a file yet so you might have to create it first.

Harnessing its incredible power

There are only two lines in my global gitignore file and they are both fairly useful pretty much all the time.

$ cat ~/.gitignore
TODO.md
playground

This 2 line file means that no matter where I am, what project I'm working on, where in the project I'm doing so, I have an easy space to stash notes, thoughts, in progress ideas, spikes, etc.

TODO.md

More often than not, I'm fiddling around with a TODO.md file. Something about writing markdown in your familiar text editor speaks to my soul. It's quick, it's easy, you have all the text editing tricks available to you, and it never does anything you wouldn't expect (looking at you auto-markdown-formatting editors). I use one or two # for headings, I use nested lists, and I ask for nothing more. Nothing more than more TODO.md files that is!

In practice I tend to just have one TODO.md file per project, right at the top, ready to pull up in a few keystrokes. Which I do often. I pull this doc up if:

  • I'm in a meeting and I just said "oh yeah that's a small thing, I'll knock it out this afternoon".
  • I'm halfway through some feature development and realize I want to make a sweeping refactor elsewhere. Toss some thoughts in the doc, and then get back to the task at hand.
  • It's the end of the day and I have to switch my brain into "feed small children" mode, thus obliterating everything work-related from my short term memory. When I open things up the next day and know exactly what the next thing to dive into was.
  • I'm preparing for a big enough refactor and I can't hold it all in my brain at once. What I'd give to have an interactive 3D playground for brain thoughts, but in the meantime a 2D text file isn't a terrible way to plan out dev work.

playground

Sometimes you need more than some human words in a markdown file to move an idea along. This is where my playground directory comes in. I can load this directory up with code that's related to a given project and keep it out of the git history. Because who doesn't like a place to play around.

I find that this directory is more useful for long running maintenance projects over fast moving greenfield ones. On the maintenance projects, I tend to find myself assembling a pile of scripts and experiments for various situations:

  • The client requests a one-time obscure data export. Whip up some CSV generation code and save that code in the playground directory.
  • The client requests a different obscure data export. Pull up the last time you did something vaguely similar and save yourself the startup time.
  • A batch of data needs to be imported just once. Might as well stash that in the chance that "just once" is actually "just a few times".
  • Kicking the tires on an integration with a third party service.

Some of these playground files end up being useful more times than I can count (eg: the ever-changing user_export.rb script). Some items get promoted into application code, which is always fun. But most files here serve their purpose and then wither away. And that's fine. It's a playground, anything goes.

Wrapping up

Having a personal space for project-specific notes and code has been helpful to me over the years as a developer on multiple projects. If you have your own organizational trick, or just want to brag about how you memorize everything without any markdown files, let me know in the comments below!

Solitary wave solutions and global well-posedness for a coupled system of gKdV equations. (arXiv:2002.09531v2 [math.AP] UPDATED)

In this work we consider the initial-value problem associated with a coupled system of generalized Korteweg-de Vries equations. We present a relationship between the best constant for a Gagliardo-Nirenberg type inequality and a criterion for the existence of global solutions in the energy space. We prove that such a constant is directly related to the existence problem of solitary-wave solutions with minimal mass, the so called ground state solutions. To guarantee the existence of ground states we use a variational method.

Extremal values of the Sackin balance index for rooted binary trees. (arXiv:1801.10418v5 [q-bio.PE] UPDATED)

Tree balance plays an important role in different research areas like theoretical computer science and mathematical phylogenetics. For example, it has long been known that under the Yule model, a pure birth process, imbalanced trees are more likely than balanced ones. Therefore, different methods to measure the balance of trees were introduced. The Sackin index is one of the most frequently used measures for this purpose. In many contexts, statements about the minimal and maximal values of this index have been discussed, but formal proofs have never been provided. Moreover, while the number of trees with maximal Sackin index as well as the number of trees with minimal Sackin index when the number of leaves is a power of 2 are relatively easy to understand, the number of trees with minimal Sackin index for all other numbers of leaves was completely unknown. In this manuscript, we fully characterize trees with minimal and maximal Sackin index and also provide formulas to explicitly calculate the number of such trees.

Special subvarieties of non-arithmetic ball quotients and Hodge Theory. (arXiv:2005.03524v1 [math.AG])

Let $Gamma subset operatorname{PU}(1,n)$ be a lattice, and $S_Gamma$ the associated ball quotient. We prove that, if $S_Gamma$ contains infinitely many maximal totally geodesic subvarieties, then $Gamma$ is arithmetic. We also prove an Ax-Schanuel Conjecture for $S_Gamma$, similar to the one recently proven by Mok, Pila and Tsimerman. One of the main ingredients in the proofs is to realise $S_Gamma$ inside a period domain for polarised integral variations of Hodge structures and interpret totally geodesic subvarieties as unlikely intersections.

Semiglobal non-oscillatory big bang singular spacetimes for the Einstein-scalar field system. (arXiv:2005.03395v1 [math-ph])

We construct semiglobal singular spacetimes for the Einstein equations coupled to a massless scalar field. Consistent with the heuristic analysis of Belinskii, Khalatnikov, Lifshitz or BKL for this system, there are no oscillations due to the scalar field. (This is much simpler than the oscillatory BKL heuristics for the Einstein vacuum equations.) Prior results are due to Andersson and Rendall in the real analytic case, and Rodnianski and Speck in the smooth near-spatially-flat-FLRW case. Similar to Andersson and Rendall we give asymptotic data at the singularity, which we refer to as final data, but our construction is not limited to real analytic solutions. This paper is a test application of tools (a graded Lie algebra formulation of the Einstein equations and a filtration) intended for the more subtle vacuum case. We use homological algebra tools to construct a formal series solution, then symmetric hyperbolic energy estimates to construct a true solution well-approximated by truncations of the formal one. We conjecture that the image of the map from final data to initial data is an open set of anisotropic initial data.

Converging outer approximations to global attractors using semidefinite programming. (arXiv:2005.03346v1 [math.OC])

This paper develops a method for obtaining guaranteed outer approximations for global attractors of continuous and discrete time nonlinear dynamical systems. The method is based on a hierarchy of semidefinite programming problems of increasing size with guaranteed convergence to the global attractor. The approach taken follows an established line of reasoning, where we first characterize the global attractor via an infinite dimensional linear programming problem (LP) in the space of Borel measures. The dual to this LP is in the space of continuous functions and its feasible solutions provide guaranteed outer approximations to the global attractor. For systems with polynomial dynamics, a hierarchy of finite-dimensional sum-of-squares tightenings of the dual LP provides a sequence of outer approximations to the global attractor with guaranteed convergence in the sense of volume discrepancy tending to zero. The method is very simple to use and based purely on convex optimization. Numerical examples with the code available online demonstrate the method.

Two-Stream FCNs to Balance Content and Style for Style Transfer. (arXiv:1911.08079v2 [cs.CV] UPDATED)

Style transfer is to render given image contents in given styles, and it has an important role in both computer vision fundamental research and industrial applications. Following the success of deep learning based approaches, this problem has been re-launched recently, but still remains a difficult task because of trade-off between preserving contents and faithful rendering of styles. Indeed, how well-balanced content and style are is crucial in evaluating the quality of stylized images. In this paper, we propose an end-to-end two-stream Fully Convolutional Networks (FCNs) aiming at balancing the contributions of the content and the style in rendered images. Our proposed network consists of the encoder and decoder parts. The encoder part utilizes a FCN for content and a FCN for style where the two FCNs have feature injections and are independently trained to preserve the semantic content and to learn the faithful style representation in each. The semantic content feature and the style representation feature are then concatenated adaptively and fed into the decoder to generate style-transferred (stylized) images. In order to train our proposed network, we employ a loss network, the pre-trained VGG-16, to compute content loss and style loss, both of which are efficiently used for the feature injection as well as the feature concatenation. Our intensive experiments show that our proposed model generates more balanced stylized images in content and style than state-of-the-art methods. Moreover, our proposed network achieves efficiency in speed.

Global Locality in Biomedical Relation and Event Extraction. (arXiv:1909.04822v2 [cs.CL] UPDATED)

Due to the exponential growth of biomedical literature, event and relation extraction are important tasks in biomedical text mining. Most work only focus on relation extraction, and detect a single entity pair mention on a short span of text, which is not ideal due to long sentences that appear in biomedical contexts. We propose an approach to both relation and event extraction, for simultaneously predicting relationships between all mention pairs in a text. We also perform an empirical study to discuss different network setups for this purpose. The best performing model includes a set of multi-head attentions and convolutions, an adaptation of the transformer architecture, which offers self-attention the ability to strengthen dependencies among related elements, and models the interaction between features extracted by multiple attention heads. Experiment results demonstrate that our approach outperforms the state of the art on a set of benchmark biomedical corpora including BioNLP 2009, 2011, 2013 and BioCreative 2017 shared tasks.

The Mapillary Traffic Sign Dataset for Detection and Classification on a Global Scale. (arXiv:1909.04422v2 [cs.CV] UPDATED)

Traffic signs are essential map features globally in the era of autonomous driving and smart cities. To develop accurate and robust algorithms for traffic sign detection and classification, a large-scale and diverse benchmark dataset is required. In this paper, we introduce a traffic sign benchmark dataset of 100K street-level images around the world that encapsulates diverse scenes, wide coverage of geographical locations, and varying weather and lighting conditions and covers more than 300 manually annotated traffic sign classes. The dataset includes 52K images that are fully annotated and 48K images that are partially annotated. This is the largest and the most diverse traffic sign dataset consisting of images from all over world with fine-grained annotations of traffic sign classes. We have run extensive experiments to establish strong baselines for both the detection and the classification tasks. In addition, we have verified that the diversity of this dataset enables effective transfer learning for existing large-scale benchmark datasets on traffic sign detection and classification. The dataset is freely available for academic research: https://www.mapillary.com/dataset/trafficsign.

COVID-19 Contact-tracing Apps: A Survey on the Global Deployment and Challenges. (arXiv:2005.03599v1 [cs.CR])

In response to the coronavirus disease (COVID-19) outbreak, there is an ever-increasing number of national governments that are rolling out contact-tracing Apps to aid the containment of the virus. The first hugely contentious issue facing the Apps is the deployment framework, i.e. centralised or decentralised. Based on this, the debate branches out to the corresponding technologies that underpin these architectures, i.e. GPS, QR codes, and Bluetooth. This work conducts a pioneering review of the above scenarios and contributes a geolocation mapping of the current deployment. The vulnerabilities and the directions of research are identified, with a special focus on the Bluetooth-based decentralised scheme.

Global Distribution of Google Scholar Citations: A Size-independent Institution-based Analysis. (arXiv:2005.03324v1 [cs.DL])

Most currently available schemes for performance based ranking of Universities or Research organizations, such as, Quacarelli Symonds (QS), Times Higher Education (THE), Shanghai University based All Research of World Universities (ARWU) use a variety of criteria that include productivity, citations, awards, reputation, etc., while Leiden and Scimago use only bibliometric indicators. The research performance evaluation in the aforesaid cases is based on bibliometric data from Web of Science or Scopus, which are commercially available priced databases. The coverage includes peer reviewed journals and conference proceedings. Google Scholar (GS) on the other hand, provides a free and open alternative to obtaining citations of papers available on the net, (though it is not clear exactly which journals are covered.) Citations are collected automatically from the net and also added to self created individual author profiles under Google Scholar Citations (GSC). This data was used by Webometrics Lab, Spain to create a ranked list of 4000+ institutions in 2016, based on citations from only the top 10 individual GSC profiles in each organization. (GSC excludes the top paper for reasons explained in the text; the simple selection procedure makes the ranked list size-independent as claimed by the Cybermetrics Lab). Using this data (Transparent Ranking TR, 2016), we find the regional and country wise distribution of GS-TR Citations. The size independent ranked list is subdivided into deciles of 400 institutions each and the number of institutions and citations of each country obtained for each decile. We test for correlation between institutional ranks between GS TR and the other ranking schemes for the top 20 institutions.

ContextNet: Improving Convolutional Neural Networks for Automatic Speech Recognition with Global Context. (arXiv:2005.03191v1 [eess.AS])

Convolutional neural networks (CNN) have shown promising results for end-to-end speech recognition, albeit still behind other state-of-the-art methods in performance. In this paper, we study how to bridge this gap and go beyond with a novel CNN-RNN-transducer architecture, which we call ContextNet. ContextNet features a fully convolutional encoder that incorporates global context information into convolution layers by adding squeeze-and-excitation modules. In addition, we propose a simple scaling method that scales the widths of ContextNet that achieves good trade-off between computation and accuracy. We demonstrate that on the widely used LibriSpeech benchmark, ContextNet achieves a word error rate (WER) of 2.1\%/4.6\% without external language model (LM), 1.9\%/4.1\% with LM and 2.9\%/7.0\% with only 10M parameters on the clean/noisy LibriSpeech test sets. This compares to the previous best published system of 2.0\%/4.6\% with LM and 3.9\%/11.3\% with 20M parameters. The superiority of the proposed ContextNet model is also verified on a much larger internal dataset.
