Residual Connections Harm Self-Supervised Abstract Feature Learning

no code implementations16 Apr 2024 Xiao Zhang, Ruoxi Jiang, William Gao, Rebecca Willett, Michael Maire

We demonstrate that adding a weighting factor to decay the strength of identity shortcuts within residual networks substantially improves semantic feature learning in the state-of-the-art self-supervised masked autoencoding (MAE) paradigm.

Training neural operators to preserve invariant measures of chaotic attractors

1 code implementation NeurIPS 2023 Ruoxi Jiang, Peter Y. Lu, Elena Orlova, Rebecca Willett

In this paper, we propose an alternative framework designed to preserve invariant measures of chaotic attractors that characterize the time-invariant statistical properties of the dynamics.

Contrastive Learning

Deep Stochastic Mechanics

2 code implementations31 May 2023 Elena Orlova, Aleksei Ustimenko, Ruoxi Jiang, Peter Y. Lu, Rebecca Willett

This paper introduces a novel deep-learning-based approach for numerical simulation of a time-evolving Schr\"odinger equation inspired by stochastic mechanics and generative diffusion models.

Embed and Emulate: Learning to estimate parameters of dynamical systems with uncertainty quantification

1 code implementation3 Nov 2022 Ruoxi Jiang, Rebecca Willett

This paper explores learning emulators for parameter estimation with uncertainty estimation of high-dimensional dynamical systems.

Contrastive Learning Time Series +2

Pure Exploration in Kernel and Neural Bandits

no code implementations NeurIPS 2021 Yinglun Zhu, Dongruo Zhou, Ruoxi Jiang, Quanquan Gu, Rebecca Willett, Robert Nowak

To overcome the curse of dimensionality, we propose to adaptively embed the feature representation of each arm into a lower-dimensional space and carefully deal with the induced model misspecification.
