I’m also excited to be presenting this work (openreview.net/forum?id=4ZX2a…) at ICCOPT at USC. Theory aside there are some applications that may interest ppl in RL, games, and performative prediction. Let me know if you are in the area and want to chat!

On my way to ICCOPT I decided to give PEPit (github.com/PerformanceEst…) a try, and I wish I had used it sooner. In just a few hours I was able to confirm our theoretical results in our recent paper and I was able to get intuition that originally took me months without using it. 1/N

I'm delighted to share that our paper has been accepted by #TMLR! We empirically observed signs of scaling laws regarding how the choice of pre-trained models affects OOD test errors and Expected Calibration Error on downstream tasks.

My thesis is now online! umontreal.scholaris.ca/items/f8670d1c… This is more than just a list of publications. I invested a lot of time and passion writing this thesis in hope that it will make for an interesting read. Here's a summary of what you'll find in it.

It's strange to think it would be at all controversial to post this. But in a time of moral decay, the obvious becomes controversial.
