Optimal minimax rate of learning interaction kernels

no code implementations28 Nov 2023 Xiong Wang, Inbar Seroussi, Fei Lu

Our tLSE method offers a straightforward approach for establishing the optimal minimax rate for models with either local or nonlocal dependency.

Droplets of Good Representations: Grokking as a First Order Phase Transition in Two Layer Networks

no code implementations5 Oct 2023 Noa Rubin, Inbar Seroussi, Zohar Ringel

A key property of deep neural networks (DNNs) is their ability to learn new features during training.

Hitting the High-Dimensional Notes: An ODE for SGD learning dynamics on GLMs and multi-index models

no code implementations17 Aug 2023 Elizabeth Collins-Woodfin, Courtney Paquette, Elliot Paquette, Inbar Seroussi

In addition to the deterministic equivalent, we introduce an SDE with a simplified diffusion coefficient (homogenized SGD) which allows us to analyze the dynamics of general statistics of SGD iterates.

no code implementations27 Jul 2023 Inbar Seroussi, Alexander A. Alemi, Moritz Helias, Zohar Ringel

State-of-the-art neural networks require extreme computational power to train.

Spectral-Bias and Kernel-Task Alignment in Physically Informed Neural Networks

no code implementations12 Jul 2023 Inbar Seroussi, Asaf Miron, Zohar Ringel

Physically informed neural networks (PINNs) are a promising emerging method for solving differential equations.

Separation of Scales and a Thermodynamic Description of Feature Learning in Some CNNs

no code implementations31 Dec 2021 Inbar Seroussi, Gadi Naveh, Zohar Ringel

Deep neural networks (DNNs) are powerful tools for compressing and distilling information.

Lower Bounds on the Generalization Error of Nonlinear Learning Models

no code implementations26 Mar 2021 Inbar Seroussi, Ofer Zeitouni

We study in this paper lower bounds for the generalization error of models derived from multi-layer neural networks, in the regime where the size of the layers is commensurate with the number of samples in the training data.

Directed polymers on infinite graphs

no code implementations19 Oct 2020 Clement Cosco, Inbar Seroussi, Ofer Zeitouni

We study the directed polymer model for general graphs (beyond $\mathbb Z^d$) and random walks.

Multi-Season Analysis Reveals the Spatial Structure of Disease Spread

1 code implementation11 Feb 2019 Inbar Seroussi, Nir Levy, Elad Yom-Tov

Understanding the dynamics of infectious disease spread in a heterogeneous population is an important factor in designing control strategies.
