Action-Conditioned Risk Gating for Safety-Critical Control under Partial Observability

Yushen Liu, Yin-Jen Chen, Ziyi Chen +4

Many safety-critical control problems are modeled as risk-sensitive partially observable Markov decision processes, where the controller must make decisions from incomplete observa…

RNA-FM: Flow-Matching Generative Model for Genome-wide RNA-Seq Prediction

Yaxuan Song, Jianan Fan, Tianyi Wang +4

Histopathology whole-slide images (WSIs) are routinely acquired in clinical practice and contain rich tissue morphology but lack direct molecular architecture and functional progra…

Distributionally Robust Multi-Objective Optimization

Yufeng Yang, Fangning Zhuo, Ziyi Chen +2

Multi-objective optimization (MOO) has received growing attention in applications that require learning under multiple criteria. However, the existing MOO formulations do not expli…

Provably Efficient Algorithms for S- and Non-Rectangular Robust MDPs with General Parameterization

Anirudh Satheesh, Ziyi Chen, Furong Huang +1

We study robust Markov decision processes (RMDPs) with general policy parameterization under s-rectangular and non-rectangular uncertainty sets. Prior work is largely limited to ta…

Zeroth-Order Methods for Stochastic Nonconvex Nonsmooth Composite Optimization

Ziyi Chen, Peiran Yu, Heng Huang

This work aims to solve a stochastic nonconvex nonsmooth composite optimization problem. Previous works on composite optimization problem requires the major part to satisfy Lipschi…
