why i love GridWorld experiments: - finish very quickly - super useful for testing out theoretical results - give great insights into what your algo. is doing - can make them as large as you like (even continuous!) - easy to generate visualizations - they remind me of my PhD dayspic.twitter.com/bQs037kP2S

"Backprop is just the chain rule" is what I used to say when I had no idea what I was talking about.

Fenchel-Rockafellar duality is a powerful tool that more people should be aware of, especially for RL! Straightforward applications of it enable offpolicy evaluation, offpolicy policy gradient/imitation learning, among others https://arxiv.org/abs/2001.01866

Can one of you wonderful vision researchers design a model to re-typeset or re-render old math/stats papers w typewritten/hand-drawn notation into a more modern style? Also if you can design a model to reverse the process, that'd be cool but less important. Thanks!

If you are in the NYC area, the NYAS ML Symposium https://www.nyas.org/events/2020/14th-annual-machine-learning-symposium/ … has an easy abstract submission deadline of Jan 20th. I've found the event a fun way to catch up with local ML folks.

For saddle point problems and more general games, gradient descent can cycle and diverge. Using an extrapolation steps adresses this issue and converges to a saddle point (Nash equilibrium). https://en.wikipedia.org/wiki/Variational_inequality …pic.twitter.com/Kpxbd2Cqbh
