Robustifying State-space Models for Long Sequences via Approximate Diagonalization

no code implementations2 Oct 2023 Annan Yu, Arnur Nigmetov, Dmitriy Morozov, Michael W. Mahoney, N. Benjamin Erichson

An example is the structured state-space sequence (S4) layer, which uses the diagonal-plus-low-rank structure of the HiPPO initialization framework.

Tuning Frequency Bias in Neural Network Training with Nonuniform Data

no code implementations28 May 2022 Annan Yu, Yunan Yang, Alex Townsend

Small generalization errors of over-parameterized neural networks (NNs) can be partially explained by the frequency biasing phenomenon, where gradient-based algorithms minimize the low-frequency misfit before reducing the high-frequency residuals.

Arbitrary-Depth Universal Approximation Theorems for Operator Neural Networks

no code implementations23 Sep 2021 Annan Yu, Chloé Becquey, Diana Halikias, Matthew Esmaili Mallory, Alex Townsend

Here, we prove that operator NNs of bounded width and arbitrary depth are universal approximators for continuous nonlinear operators.
