SHAP-Guided Kernel Actor-Critic for Explainable Reinforcement Learning

ICML 2026poster

Actor-critic (AC) methods are a cornerstone of reinforcement learning (RL) but offer limited interpretability. Current explainable RL methods seldom use *state attributions* to assist training. Rather, they treat all state features equally, thereby neglecting the heterogeneous impacts of individual …

Privacy-Preserving V2X Collaborative Perception Integrating Unknown Collaborators

AAAI 2025technical

Vehicle-to-everything (V2X) collaborative perception has recently gained increasing attention in autonomous driving due to its ability to enhance scene understanding by integrating information from other collaborators, e.g. vehicles or infrastructure. Existing algorithms usually share deep features…

RayFusion: Ray Fusion Enhanced Collaborative Visual Perception

NeurIPS 2025poster

Collaborative visual perception methods have gained widespread attention in the autonomous driving community in recent years due to their ability to address sensor limitation problems. However, the absence of explicit depth information often makes it difficult for camera-based perception systems, e.…

Sample-Efficient Tabular Self-Play for Offline Robust Reinforcement Learning

NeurIPS 2025poster

Multi-agent reinforcement learning (MARL), as a thriving field, explores how multiple agents independently make decisions in a shared dynamic environment. Due to environmental uncertainties, policies in MARL must remain robust to tackle the sim-to-real gap. We focus on robust two-player zero-sum Mar…

Exploring Base-Class Suppression with Prior Guidance for Bias-Free One-Shot Object Detection

AAAI 2024technical

One-shot object detection (OSOD) aims to detect all object instances towards the given category specified by a query image. Most existing studies in OSOD endeavor to establish effective cross-image correlation with limited query information, however, ignoring the problems of the model bias towards t…

IFTR: An Instance-Level Fusion Transformer for Visual Collaborative Perception

ECCV 2024poster

"Multi-agent collaborative perception has emerged as a widely recognized technology in the field of autonomous driving in recent years. However, current collaborative perception predominantly relies on LiDAR point clouds, with significantly less attention given to methods using camera images. This s…

Provable Memory Efficient Self-Play Algorithm for Model-free Reinforcement Learning

ICLR 2024poster

The thriving field of multi-agent reinforcement learning (MARL) studies how a group of interacting agents make decisions autonomously in a shared dynamic environment. Existing theoretical studies in this area suffer from at least two of the following obstacles: memory inefficiency, the heavy depende…
