What's everyone's favorite package/approach to engage with tensorflow/keras in R? (trying to teach a short course, and don't want to require ppl to know python; unfortunately reticulate->miniconda seems to have a bug in windows =[)

I got my 3rd quarter performance review today...

Just came across a nugget of wisdom from a mathematician that I thought I would share: "A drunk man will find his way home, but a drunk bird may get lost forever" - Shizuo Kakutani

She may look cute, but her favorite activity is eye gouging. no joke. (to be fair, it was a rough week for everyone...)

We were motivated by challenges of stochastic optimization for training neural networks (esp. in reinforcement learning). Often as samples grow, would like to grow network complexity... how should this be done? (2/n)

Why aren't there any good golden snitch costumes for infants? Also, how dare you suggest I plan to dress my baby up as the golden snitch while I watch the secrets of dumbledore... (when it is streamable)

Have you ever had an SVM substantially outperform a reasonably tuned logistic regression?
When was the last time you used SVM?🤔 What was the performance like?

This is quite useful (especially for people looking to get into ML); my summary of the thread is that the ability to engage in simple, fit-for-purpose modeling, and then validate+communicate your models trumps all else.
Universities do a terrible job teaching machine learning. Not only do they give you critically out-of-date information, but they focus most of their time on the least important aspects. Here 5 things everyone in industry WISHES your professor taught you:

I think something intimated, but unwritten, is the value in understanding the FEW situations where a very simple modeling technique will NOT suffice. Most of the time, at the modeling stage, glm(...) or glmnet(...), or xgboost(...) is totally fine.

awesome work by Jean on how to get the most out of neural networks (with less work) for high dimensional biomedical problems!

Really excellent tutorial! (By far the clearest treatment of semiparametric inference/efficiency I have read!)
I wrote a review & tutorial illustrating how I think about semiparametric / doubly robust / TMLE / DML methods: arxiv.org/pdf/2203.06469.pdf It builds on workshops I've given in the past using these slides: xitter.gq/edwardhkennedy/status/… (next one's at ACIC in May: ctml.berkeley.edu/american-c…)

Been making some intro asymptotic stats theory videos (for my course). Perhaps others might find them useful. Thumbnails are pictures of the baby! More videos to come soon! youtube.com/playlist?list=PL…

Someone told me that the thumbnails aren't professional, so if you can think of more professional poses or attire for Rose (the baby), please let me know.

Great article (and quite accessible!)
Prof. Bradley Efron has written a lovely article about statistics in the age of deep learning. I hope this becomes essential reading for anyone engaged in machine learning. statweb.stanford.edu/~ckirby…

really good general presentation advice!
I've put together presentation advice for econ theory talks. It's coming that time of year when many young theorists rapidly learn to present papers, so I thought this might be useful. drive.google.com/file/d/1SHi…

A very nice analysis of what is going on with the Pfizer efficacy data against delta variant in Israel (and why it actually tells a consistent story that the vaccine is still highly effective). Great example of Simpson's paradox/confounding!
In this blog post, I go through the recent Israeli data in detail to explore what it tells us about efficacy of the Pfizer vaccine vs. severe disease with the Delta variant. #deltavariant #israel #pfizervaccine #vaccines #covid19pandemic covid-datascience.com/post/i…

Awesome and fascinating talk by @uhlily on "the construction of social causation" at UW biostat today! I encourage everyone to read all of her stuff! (and consider how stat/biostat/epi analyses create and reaffirm social norms!)

I'm planning a one-off guided data analysis in R for a group of high school students. Any suggestions on how to streamline the setup process? I was thinking maybe Rstudio cloud? (and just have everyone run stuff through their browser)

A pretty brilliant piece by @uhlily challenging the way statistics and causal inference is used to engage with racism
Thank you to @yc_yc_yc_yc for sharing this great read by @uhlily phenomenalworld.org/analysis…. I encourage my @UWBiostat colleagues to give it a read. #causaltwitter

It's going to be pretty fun!!! I may even tell my famed "biostatistician joke"
Check out the amazing list of contributors to the upcoming (virtual) Sixth Seattle Symposium in Biostatistics! Four days of fascinating talks, including session on data science in COVID-19. See full program at bit.ly/368zm08. Register by Nov 17 to join in!
