A Viget Exploration: How Tech Can Help in a Pandemic

Viget Explorations have always been the result of our shared curiosities. They’re usually a spontaneous outcome of team downtime and a shared problem we’ve experienced. We use our Explorations to pursue our diverse interests and contribute to the conversations about building a better digital world.

As the COVID-19 crisis emerged, we were certainly experiencing a shared problem. As a way to keep busy and manage our anxieties, a small team came together to dive into how technology has helped, and, unfortunately, hindered the community response to the current pandemic.

We started by researching the challenges we saw: information overload, a lack of clarity, individual responsibility, and change. Then we brainstormed possible technical solutions that could further improve how communities respond to a pandemic. Click here to see our Exploration on some possible ways to take the panic out of pandemics.

While we aren’t currently pursuing the solutions outlined in the Exploration, we’d love to hear what you think about these approaches, as well as any ideas you have for how technology can help address the outlined challenges.

Please note, this Exploration doesn’t provide medical information. Visit the Center for Disease Control’s website for current information and COVID-19, its symptoms, and treatments.

At Viget, we’re adjusting to this crisis for the safety of our clients, our staff, and our communities. If you’d like to hear from Viget's co-founder, Brian Williams, you can read his article on our response to the situation.

Pandemic Poetry

Viget is replete with literature enthusiasts. We have a book club, blog posts about said book club, and a #poetry channel on Slack for sharing Wendell Berry and Emily Dickinson. Before the pandemic it saw only occasional activity. That was until our Employee Engagement Manager, Aubrey Lear, popped up one day with a proposal: a month-long haiku challenge. (Hat tip to Nicole Gulotta for the excellent prompts.)

Haikus have long been beloved by Vigets. (In fact we have a #haiku channel too, but all the action tends to go down in #poetry.) There’s something about the form’s constraints, pithiness, and symmetry that appeals to us — a bunch of creatives, developers, and strategists who value elegant solutions. What we didn’t know was that a haiku-a-thon would also become a highlight of our very, very many Work From Home days.

For my part, writing haikus has become a charming distraction from worry. When I find my brain fidgeting over Covid-19 what-if scenarios, I set it a task. 5-7-5. Stack those syllables up, break ‘em down. How far can I push the confines of that structure? Where should the line breaks be? One run-on sentence? Find a punchline? It’s a nice little bit of syntactic Tetris. It stops me going down mental rabbit holes — a palette-cleansing exercise after a day’s bad news.

Then there’s the getting-to-know-you benefit that comes from Vigets sharing their daily haikus, each interpreting the prompts differently, offering a unique and condensed take on things common to us all.


There’s Elyse with her gorgeous personification of household objects:

Around the House

The small tea kettle

is now forming a union.

She demands more pay.


Or Laura, musing on the mundane things we miss:

Something you long for

strolling up and down

the aisles, browsing away

wonder everywhere

just taking my time

tossing products in my cart

ye olde target run


Josh’s odes are always a pick-me-up:

Nourishing Meal

O orange powder

On mac, Doritos, Cheetos

Finger-licking gewd.


While Grace’s are thoughtful and profound:

Thoughts while Driving

Tis human nature

We struggle to grasp the weight

Till it’s upon us


There’s Peyton, with his humorous wordplay:

Plant Friends

Plant friends everywhere

Watch them grow from far away

Then come back to them

Plant friends everywhere

Water them with Zooms and calls

They’ll water you too


And Claire, who grounds us in reality:

While folding laundry

gym shorts and sports bras

mostly what I’m folding now

goodbye skirts and jeans


Kate is sparky:

Lighting a candle

lighter fluid thrills

fingertips quiver, recoil

fire takes hold within


While I find the whole thing cathartic:

Breath

Old friend — with me since

birth — whom I seldom take time

to appreciate.


Our first #30daysfohaikuchallenge is over now, so we’ve decided to start another. Won’t you join us? Prompts are below and you can share your haiku in the comments.

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!

The 2d-directed spanning forest converges to the Brownian web. (arXiv:1805.09399v3 [math.PR] UPDATED)

The two-dimensional directed spanning forest (DSF) introduced by Baccelli and Bordenave is a planar directed forest whose vertex set is given by a homogeneous Poisson point process $mathcal{N}$ on $mathbb{R}^2$. If the DSF has direction $-e_y$, the ancestor $h(u)$ of a vertex $u in mathcal{N}$ is the nearest Poisson point (in the $L_2$ distance) having strictly larger $y$-coordinate. This construction induces complex geometrical dependencies. In this paper we show that the collection of DSF paths, properly scaled, converges in distribution to the Brownian web (BW). This verifies a conjecture made by Baccelli and Bordenave in 2007.

Expansion of Iterated Stratonovich Stochastic Integrals of Arbitrary Multiplicity Based on Generalized Iterated Fourier Series Converging Pointwise. (arXiv:1801.00784v9 [math.PR] UPDATED)

The article is devoted to the expansion of iterated Stratonovich stochastic integrals of arbitrary multiplicity $k$ $(kinmathbb{N})$ based on the generalized iterated Fourier series. The case of Fourier-Legendre series as well as the case of trigonotemric Fourier series are considered in details. The obtained expansion provides a possibility to represent the iterated Stratonovich stochastic integral in the form of iterated series of products of standard Gaussian random variables. Convergence in the mean of degree $2n$ $(nin mathbb{N})$ of the expansion is proved. Some modifications of the mentioned expansion were derived for the case $k=2$. One of them is based of multiple trigonomentric Fourier series converging almost everywhere in the square $[t, T]^2$. The results of the article can be applied to the numerical solution of Ito stochastic differential equations.

High dimensional expanders and coset geometries. (arXiv:1710.05304v3 [math.CO] UPDATED)

High dimensional expanders is a vibrant emerging field of study. Nevertheless, the only known construction of bounded degree high dimensional expanders is based on Ramanujan complexes, whereas one dimensional bounded degree expanders are abundant.

In this work, we construct new families of bounded degree high dimensional expanders obeying the local spectral expansion property. This property has a number of important consequences, including geometric overlapping, fast mixing of high dimensional random walks, agreement testing and agreement expansion. Our construction also yields new families of expander graphs which are close to the Ramanujan bound, i.e., their spectral gap is close to optimal.

The construction is quite elementary and it is presented in a self contained manner; This is in contrary to the highly involved previously known construction of the Ramanujan complexes. The construction is also very symmetric (such symmetry properties are not known for Ramanujan complexes) ; The symmetry of the construction could be used, for example, in order to obtain good symmetric LDPC codes that were previously based on Ramanujan graphs.

The main tool that we use for is the theory of coset geometries. Coset geometries arose as a tool for studying finite simple groups. Here, we show that coset geometries arise in a very natural manner for groups of elementary matrices over any finitely generated algebra over a commutative unital ring. In other words, we show that such groups act simply transitively on the top dimensional face of a pure, partite, clique complex.

Given an one-dimensional Lorenz-like expanding map we prove that the conditionlinebreak $P_{top}(phi,partial mathcal{P},ell)<P_{top}(phi,ell)$ (see, subsection 2.4 for definition), introduced by Buzzi and Sarig in [1] is satisfied for all continuous potentials $phi:[0,1]longrightarrow mathbb{R}$. We apply this to prove that quasi-H"older-continuous potentials (see, subsection 2.2 for definition) have at most one equilibrium measure and we construct a family of continuous but not H"older and neither weak H"older continuous potentials for which we observe phase transitions. Indeed, this class includes all H"older and weak-H"older continuous potentials and form an open and [2].

Filtered expansions in general relativity II. (arXiv:2005.03390v1 [math-ph])

This is the second of two papers in which we construct formal power series solutions in external parameters to the vacuum Einstein equations, implementing one bounce for the Belinskii-Khalatnikov-Lifshitz (BKL) proposal for spatially inhomogeneous spacetimes. Here we show that spatially inhomogeneous perturbations of spatially homogeneous elements are unobstructed. A spectral sequence for a filtered complex, and a homological contraction based on gauge-fixing, are used to do this.

Packing of spanning mixed arborescences. (arXiv:2005.03218v1 [math.CO])

In this paper, we characterize a mixed graph $F$ which contains $k$ edge and arc disjoint spanning mixed arborescences $F_{1}, ldots, F_{k}$, such that for each $v in V(F)$, the cardinality of ${i in [k]: v ext{ is the root of } F_{i}}$ lies in some prescribed interval. This generalizes both Nash-Williams and Tutte's theorem on spanning tree packing for undirected graphs and the previous characterization on digraphs which was given by Cai [in: Arc-disjoint arborescences of digraphs, J. Graph Theory 7(2) (1983), 235-240] and Frank [in: On disjoint trees and arborescences, Algebraic Methods in Graph Theory, Colloquia Mathematica Soc. J. Bolyai, Vol. 25 (North-Holland, Amsterdam) (1978), 159-169].

A Note on Approximations of Fixed Points for Nonexpansive Mappings in Norm-attainable Classes. (arXiv:2005.03069v1 [math.FA])

Let $H$ be an infinite dimensional, reflexive, separable Hilbert space and $NA(H)$ the class of all norm-attainble operators on $H.$ In this note, we study an implicit scheme for a canonical representation of nonexpansive contractions in norm-attainable classes.

Asymptotic expansions of eigenvalues by both the Crouzeix-Raviart and enriched Crouzeix-Raviart elements. (arXiv:1902.09524v2 [math.NA] UPDATED)

Asymptotic expansions are derived for eigenvalues produced by both the Crouzeix-Raviart element and the enriched Crouzeix--Raviart element. The expansions are optimal in the sense that extrapolation eigenvalues based on them admit a fourth order convergence provided that exact eigenfunctions are smooth enough. The major challenge in establishing the expansions comes from the fact that the canonical interpolation of both nonconforming elements lacks a crucial superclose property, and the nonconformity of both elements. The main idea is to employ the relation between the lowest-order mixed Raviart--Thomas element and the two nonconforming elements, and consequently make use of the superclose property of the canonical interpolation of the lowest-order mixed Raviart--Thomas element. To overcome the difficulty caused by the nonconformity, the commuting property of the canonical interpolation operators of both nonconforming elements is further used, which turns the consistency error problem into an interpolation error problem. Then, a series of new results are obtained to show the final expansions.

JASS: Japanese-specific Sequence to Sequence Pre-training for Neural Machine Translation. (arXiv:2005.03361v1 [cs.CL])

Neural machine translation (NMT) needs large parallel corpora for state-of-the-art translation quality. Low-resource NMT is typically addressed by transfer learning which leverages large monolingual or parallel corpora for pre-training. Monolingual pre-training approaches such as MASS (MAsked Sequence to Sequence) are extremely effective in boosting NMT quality for languages with small parallel corpora. However, they do not account for linguistic information obtained using syntactic analyzers which is known to be invaluable for several Natural Language Processing (NLP) tasks. To this end, we propose JASS, Japanese-specific Sequence to Sequence, as a novel pre-training alternative to MASS for NMT involving Japanese as the source or target language. JASS is joint BMASS (Bunsetsu MASS) and BRSS (Bunsetsu Reordering Sequence to Sequence) pre-training which focuses on Japanese linguistic units called bunsetsus. In our experiments on ASPEC Japanese--English and News Commentary Japanese--Russian translation we show that JASS can give results that are competitive with if not better than those given by MASS. Furthermore, we show for the first time that joint MASS and JASS pre-training gives results that significantly surpass the individual methods indicating their complementary nature. We will release our code, pre-trained models and bunsetsu annotated data as resources for researchers to use in their own NLP tasks.

Regression Forest-Based Atlas Localization and Direction Specific Atlas Generation for Pancreas Segmentation. (arXiv:2005.03345v1 [cs.CV])

This paper proposes a fully automated atlas-based pancreas segmentation method from CT volumes utilizing atlas localization by regression forest and atlas generation using blood vessel information. Previous probabilistic atlas-based pancreas segmentation methods cannot deal with spatial variations that are commonly found in the pancreas well. Also, shape variations are not represented by an averaged atlas. We propose a fully automated pancreas segmentation method that deals with two types of variations mentioned above. The position and size of the pancreas is estimated using a regression forest technique. After localization, a patient-specific probabilistic atlas is generated based on a new image similarity that reflects the blood vessel position and direction information around the pancreas. We segment it using the EM algorithm with the atlas as prior followed by the graph-cut. In evaluation results using 147 CT volumes, the Jaccard index and the Dice overlap of the proposed method were 62.1% and 75.1%, respectively. Although we automated all of the segmentation processes, segmentation results were superior to the other state-of-the-art methods in the Dice overlap.
