Teacher-Student Architecture for Knowledge Learning: A Survey

Chengming Hu, Xuan Li, Dan Liu +3

Although Deep Neural Networks (DNNs) have shown a strong capacity to solve large-scale problems in many areas, such DNNs with voluminous parameters are hard to be deployed in a rea…

Novel multilevel preconditioners for the systems arising from plane wave discretization of Helmholtz equations with large wave numbers

Qiya Hu, Xuan Li

In this paper we are concerned with fast algorithms for the systems arising from the plane wave discretizations for two-dimensional Helmholtz equations with large wave numbers. We…

Directed Greybox Fuzzing with Stepwise Constraint Focusing

Xiaofan Li, Xuan Li, Guangfa Lv +2

Dynamic data flow analysis has been widely used to guide greybox fuzzing. However, traditional dynamic data flow analysis tends to go astray in the massive path tracking and requir…

BFEMP: Interpenetration-Free MPM-FEM Coupling with Barrier Contact

Xuan Li, Yu Fang, Minchen Li +1

This paper introduces BFEMP, a new approach for monolithically coupling the Material Point Method (MPM) with the Finite Element Method (FEM) through barrier energy-based particle-m…

Complete quantum state selectivity in cold molecular beams using deflection-resistant dark states in a STIRAP configuration

Xuan Li, Asaf Eilam, Moshe Shapiro

One of the main goals of chemical dynamics is the creation of molecular beams composed of a single (vibrational, rotational, and magnetic) quantum state of choice. In this paper we…

AuTAgent: A Reinforcement Learning Framework for Tool-Augmented Audio Reasoning

Siqian Tong, Xuan Li, Yiwei Wang +5

Large Audio Language Models (LALMs) excel at perception but struggle with complex reasoning requiring precise acoustic measurements. While external tools can extract fine-grained f…
