Subspace-Aware Feature Reshaping for Open-Set Graph Class-Incremental Learning

ICML 2026poster

Graph class-incremental learning (GCIL) has emerged to address the challenge of learning from dynamically evolving graphs, which continuously learns new classes over a sequence of tasks while retaining performance on previously seen classes. However, existing GCIL methods assume a closed-set test di…

Controllable Traffic Simulation through LLM-Guided Hierarchical Reasoning and Refinement

IROS 2025

Evaluating autonomous driving systems in complex and diverse traffic scenarios through controllable simulation is essential to ensure their safety and reliability. However, existing traffic simulation methods face challenges in their controllability. To address this, we propose a novel diffusion-bas

Distribution-Induced Bidirectional Generative Adversarial Network for Graph Representation Learning

CVPR 2020poster

Graph representation learning aims to encode all nodes of a graph into low-dimensional vectors that will serve as input of many computer vision tasks. However, most existing algorithms ignore the existence of inherent data distribution and even noises. This may significantly increase the phenomenon…
