Stochastic Quantum Sampling for Non-Logconcave Distributions and Estimating Partition Functions

no code implementations17 Oct 2023 Guneykan Ozgul, Xiantao Li, Mehrdad Mahdavi, Chunhao Wang

We also incorporate a stochastic gradient oracle that implements the quantum walk operators inexactly by only using mini-batch gradients.

Efficient Quantum Algorithms for Quantum Optimal Control

no code implementations5 Apr 2023 Xiantao Li, Chunhao Wang

In this paper, we present efficient quantum algorithms that are exponentially faster than classical algorithms for solving the quantum optimal control problem.

The Mori-Zwanzig formulation of deep learning

no code implementations12 Sep 2022 Daniele Venturi, Xiantao Li

We develop a new formulation of deep learning based on the Mori-Zwanzig (MZ) formalism of irreversible statistical mechanics.

Stability Preserving Data-driven Models With Latent Dynamics

In this paper, we introduce a data-driven modeling approach for dynamics problems with latent variables.

A Local Convergence Theory for the Stochastic Gradient Descent Method in Non-Convex Optimization With Non-isolated Local Minima

no code implementations21 Mar 2022 Taehee Ko, Xiantao Li

Loss functions with non-isolated minima have emerged in several machine learning problems, creating a gap between theory and practice.

Error Bounds of the Invariant Statistics in Machine Learning of Ergodic Itô Diffusions

no code implementations21 May 2021 He Zhang, John Harlim, Xiantao Li

We find that sufficient conditions for such a linear dependence result are through learning algorithms that produce a uniformly Lipschitz and consistent estimator in the hypothesis space that retains certain characteristics of the drift coefficients, such as the usual linear growth condition that guarantees the existence of solutions of the underlying SDEs.

Projection based model reduction for the immersed boundary method

no code implementations28 Jan 2021 Yushuang Luo, Xiantao Li, Wenrui Hao

Fluid-structure interactions are central to many bio-molecular processes, and they impose a great challenge for computational and modeling methods.
