MetaDAT: Generalizable Trajectory Prediction Via Meta Pre-Training and Data-Adaptive Test-Time Updating

ICRA 2026poster

Existing trajectory prediction methods exhibit significant performance degradation under distribution shifts during test time. Although test-time training techniques have been explored to enable adaptation, current approaches rely on an offline pre-trained predictor that lacks online learning flexib…

ContextAware: A Multi-Agent Framework for Detecting Harmful Image-Based Comments on Social Media

IJCAI 2025

Detecting hidden stigmatization in social media poses significant challenges due to semantic misalignments between textual and visual modalities, as well as the subtlety of implicit stigmatization. Traditional approaches often fail to capture these complexities in real-world, multimodal content. To

Frame-By-Frame Motion Retargeting With Self-Collision Avoidance From Diverse Human Demonstrations

RA-L 2024

Human-robot motion retargeting is a complex nonlinear problem, due to heterogeneous kinematic configuration between human and robot. Recent efforts aim to tackle the generalizability of motion retargeting on diverse robots, yet challenges persist in handling unseen human motions with varying scales

Large Language Model as a Policy Teacher for Training Reinforcement Learning Agents

IJCAI 2024poster

Recent studies have uncovered the potential of Large Language Models (LLMs) in addressing complex sequential decision-making tasks through the provision of high-level instructions. However, LLM-based agents lack specialization in tackling specific target problems, particularly in real-time dynamic e…

FEND: A Future Enhanced Distribution-Aware Contrastive Learning Framework for Long-Tail Trajectory Prediction

CVPR 2023poster

Predicting the future trajectories of the traffic agents is a gordian technique in autonomous driving. However, trajectory prediction suffers from data imbalance in the prevalent datasets, and the tailed data is often more complicated and safety-critical. In this paper, we focus on dealing with the…

SwinLSTM: Improving Spatiotemporal Prediction Accuracy using Swin Transformer and LSTM

ICCV 2023poster

Integrating CNNs and RNNs to capture spatiotemporal dependencies is a prevalent strategy for spatiotemporal prediction tasks. However, the property of CNNs to learn local spatial information decreases their efficiency in capturing spatiotemporal dependencies, thereby limiting their prediction accura…

SR-LSTM: State Refinement for LSTM Towards Pedestrian Trajectory Prediction

CVPR 2019poster

In crowd scenarios, reliable trajectory prediction of pedestrians requires insightful understanding of their social behaviors. These behaviors have been well investigated by plenty of studies, while it is hard to be fully expressed by hand-craft rules. Recent studies based on LSTM networks have show…
