A Theory of Deep Learning

https://elonlit.com/images/flowers.png
Deep learning works by memorizing noise and signal, with the signal channel allowing generalization and the reservoir containing memorized noise. A new theory explains generalization and provides a way to train directly on population risk, eliminating overfitting and suggesting more efficient model architectures.

Learning the Integral of a Diffusion Model

https://sander.ai/images/flow_maps_diagram001.png
Flow maps are a way to speed up sampling from diffusion models by predicting any point on a path from any other point on that same path, rather than just the tangent direction at each point. They can be used for faster sampling, more efficient reward-based learning, and improved sampling steerability, but training a flow map is significantly more involved than training a diffusion model.
