Towards efficient quantum algorithms for diffusion probability models

no code implementations20 Feb 2025 Yunfei Wang, Ruoxi Jiang, Yingda Fan, Xiaowei Jia, Jens Eisert, Junyu Liu, Jin-Peng Liu

As such, this work represents one of the most direct and pragmatic applications of quantum algorithms to large-scale machine learning models, presumably talking substantial steps towards demonstrating the practical utility of quantum computing.

Nested Diffusion Models Using Hierarchical Latent Priors

no code implementations8 Dec 2024 Xiao Zhang, Ruoxi Jiang, Rebecca Willett, Michael Maire

Our approach employs a series of diffusion models to progressively generate latent variables at different semantic levels.

Embed and Emulate: Contrastive representations for simulation-based inference

no code implementations27 Sep 2024 Ruoxi Jiang, Peter Y. Lu, Rebecca Willett

E&E learns a low-dimensional latent embedding of the data (i. e., a summary statistic) and a corresponding fast emulator in the latent space, eliminating the need to run expensive simulations or a high dimensional emulator during inference.

Residual Connections Harm Generative Representation Learning

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

We show that introducing a weighting factor to reduce the influence of identity shortcuts in residual networks significantly enhances semantic feature learning in generative representation learning frameworks, such as masked autoencoders (MAEs) and diffusion models.

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.

Deep Stochastic Mechanics

1 code implementation31 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.

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.
