ROAD: Responsibility-Oriented Reward Design for Reinforcement Learning in Autonomous Driving

RA-L 2026

Reinforcement learning (RL) in autonomous driving employs a trial-and-error mechanism, enhancing robustness in unpredictable environments. However, crafting effective reward functions remains challenging, as conventional approaches rely heavily on manual design and demonstrate limited efficacy in co

Adapt Foundational Segmentation Models with Heterogeneous Searching Space

ICCV 2025poster

Foundation Segmentation Models (FSMs) show suboptimal performance on unconventional image domains like camouflage objects. Fine-tuning is often impractical due to data preparation challenges, time limits, and optimization issues. To boost segmentation performance while keeping zero-shot features, on…

CamoTeacher: Dual-Rotation Consistency Learning for Semi-Supervised Camouflaged Object Detection

ECCV 2024poster

"Existing camouflaged object detection (COD) methods depend heavily on large-scale pixel-level annotations. However, acquiring such annotations is laborious due to the inherent camouflage characteristics of the objects. Semi-supervised learning offers a promising solution to this challenge. Yet, its…

Dream to Adapt: Meta Reinforcement Learning by Latent Context Imagination and MDP Imagination

RA-L 2024

Meta reinforcement learning (Meta RL) has been amply explored to quickly learn an unseen task by transferring previously learned knowledge from similar tasks. However, most state-of-the-art Meta RL algorithms require the meta-training tasks to have a dense coverage of the task distribution and a gre

Robust Multi-Agent Reinforcement Learning via Adversarial Regularization: Theoretical Foundation and Stable Algorithms

NeurIPS 2023poster

Multi-Agent Reinforcement Learning (MARL) has shown promising results across several domains. Despite this promise, MARL policies often lack robustness and are therefore sensitive to small changes in their environment. This presents a serious concern for the real world deployment of MARL algorithms,…

Improved Robustness and Safety for Pre-Adaptation of Meta Reinforcement Learning with Prior Regularization

IROS 2022poster

Meta Reinforcement Learning (Meta-RL) has seen substantial advancements recently. In particular, off-policy methods were developed to improve the data efficiency of Meta-RL techniques. Probabilistic embeddings for actor-critic \boldsymbol{RL}\boldsymbol{RL} (PEARL) is a leading approach for multi-MD…

Monocular 3D Vehicle Detection Using Uncalibrated Traffic Cameras through Homography

IROS 2021poster

This paper proposes a method to extract the position and pose of vehicles in the 3D world from a single traffic camera. Most previous monocular 3D vehicle detection algorithms focused on cameras on vehicles from the perspective of a driver, and assumed known intrinsic and extrinsic calibration. On t…
