Data-driven discretization: a method for systematic coarse graining of partial differential equations

3 code implementations15 Aug 2018 Yohai Bar-Sinai, Stephan Hoyer, Jason Hickey, Michael P. Brenner

Many problems in theoretical physics are centered on representing the behavior of a physical theory at long wave lengths and slow frequencies by integrating out degrees of freedom which change rapidly in time and space.

Charting the Topography of the Neural Network Landscape with Thermal-Like Noise

no code implementations3 Apr 2023 Theo Jules, Gal Brener, Tal Kachman, Noam Levi, Yohai Bar-Sinai

The training of neural networks is a complex, high-dimensional, non-convex and noisy optimization problem whose theoretical understanding is interesting both from an applicative perspective and for fundamental reasons.

Grokking in Linear Estimators -- A Solvable Model that Groks without Understanding

no code implementations25 Oct 2023 Noam Levi, Alon Beck, Yohai Bar-Sinai

Grokking is the intriguing phenomenon where a model learns to generalize long after it has fit the training data.
