Full Lyapunov Spectra of Random Neural Networks, Part I: Finite-Time and Asymptotic Theory
Haoyu Albert Wang, Wei P. Dai
We develop a dynamical mean-field framework for the full finite-time and stationary asymptotic Lyapunov spectra of random recurrent neural networks. At finite observation time, an…

Continual Alignment for SAM: Rethinking Foundation Models for Medical Image Segmentation in Continual Learning
Jiayi Wang, Wei Dai, Haoyu Wang +3
In medical image segmentation, heterogeneous privacy policies across institutions often make joint training on pooled datasets infeasible, motivating continual image segmentation-l…
