Attention Retention for Continual Learning with Vision Transformers

AAAI 2026technical

Continual learning (CL) empowers AI systems to progressively acquire knowledge from non-stationary data streams. However, catastrophic forgetting remains a critical challenge. In this work, we identify attention drift in Vision Transformers as a primary source of catastrophic forgetting, where the a

Not All Tokens Are Meant to Be Forgotten

AAAI 2026technical

Large Language Models (LLMs), pre-trained on massive text corpora, exhibit remarkable human-level language understanding, reasoning, and decision-making abilities. However, they tend to memorize unwanted information, such as private or copyrighted content, raising significant privacy and legal conce

WalkGPT: Grounded Vision-Language Conversation with Depth-Aware Segmentation for Pedestrian Navigation

CVPR 2026

Ensuring accessible pedestrian navigation requires reasoning about both semantic and spatial aspects of complex urban scenes, a challenge that existing Large Vision-Language Models (LVLMs) struggle to meet. Although these models can describe visual content, their lack of explicit grounding leads to

HiTail: Hierarchical Neural Planner for Adaptive and Flexible Long-Tail Trajectory Planning

IROS 2025

A planner for autonomous vehicles must be capable of operating in diverse and complex real-world environments. However, learning-based planners often struggle with limited generalization due to the long-tail distribution in datasets. Moreover, the black-box nature of neural networks limits their int
