HAMLET: Switch Your Vision-Language-Action Model into a History-Aware Policy

ICLR 2026poster

Inherently, robotic manipulation tasks are history-dependent: leveraging past context could be beneficial. However, most existing Vision-Language-Action models (VLAs) have been designed without considering this aspect, i.e., they rely solely on the current observation, ignoring preceding context. In…

Mamba Drafters for Speculative Decoding

EMNLP 2025

Speculative decoding has emerged as a promising approach to accelerating large language model (LLM) generation using a fast drafter while maintaining alignment with the target model’s distribution. However, existing approaches face a trade-off: external drafters offer flexibility but can suffer from

Think Clearly: Improving Reasoning via Redundant Token Pruning

EMNLP 2025

Recent large language models have shown promising capabilities in long-form reasoning, following structured chains of thought before arriving at a final answer. However, we observe that these reasoning paths tend to include substantial redundancy; analyzing attention patterns reveals that attention

Adversarial Robustification via Text-to-Image Diffusion Models

ECCV 2024oral

"Adversarial robustness has been conventionally believed as a challenging property to encode for neural networks, requiring plenty of training data. In the recent paradigm of adopting off-the-shelf models, however, access to their training data is often infeasible or not practical, while most of suc…

Modality-Agnostic Self-Supervised Learning with Meta-Learned Masked Auto-Encoder

NeurIPS 2023poster

Despite its practical importance across a wide range of modalities, recent advances in self-supervised learning (SSL) have been primarily focused on a few well-curated domains, e.g., vision and language, often relying on their domain-specific knowledge. For example, Masked Auto-Encoder (MAE) has bec…
