Online Long-run Constrained Optimization

no code implementations4 Nov 2023 Shijie Pan, Wenjie Huang

In this paper, a novel Follow-the-Perturbed-Leader type algorithm is proposed and analyzed for solving general long-term constrained optimization problems in online manner, where the objective and constraints are not necessarily convex.

Distributional Reinforcement Learning with Online Risk-awareness Adaption

no code implementations8 Oct 2023 Yupeng Wu, Wenjie Huang

The use of reinforcement learning (RL) in practical applications requires considering sub-optimal outcomes, which depend on the agent's familiarity with the uncertain environment.

Waveform Design for Mutual Interference Mitigation in Automotive Radar

no code implementations8 Aug 2022 Arindam Bose, Bo Tang, Wenjie Huang, Mojtaba Soltanalian, Jian Li

The mutual interference between similar radar systems can result in reduced radar sensitivity and increased false alarm rates.

Preference Robust Optimization with Quasi-Concave Choice Functions for Multi-Attribute Prospects

no code implementations31 Aug 2020 Jian Wu, William B. Haskell, Wenjie Huang, Huifu Xu

Preference robust choice models concern decision-making problems where the decision maker's (DM) utility/risk preferences are ambiguous and the evaluation is based on the worst-case utility function/risk measure from a set of plausible utility functions/risk measures.

Online non-convex learning for river pollution source identification

no code implementations22 May 2020 Wenjie Huang, Jing Jiang, Xiao Liu

In this paper, novel gradient-based online learning algorithms are developed to investigate an important environmental application: real-time river pollution source identification, which aims at estimating the released mass, location, and time of a river pollution source based on downstream sensor data monitoring the pollution concentration.

Data-driven satisficing measure and ranking

no code implementations1 Jul 2018 Wenjie Huang

We propose an computational framework for real-time risk assessment and prioritizing for random outcomes without prior information on probability distributions.
