RESTRAIN: From Spurious Votes to Signals — Self-Training RL with Self-Penalization

ICLR 2026poster

Reinforcement learning with human-annotated data has boosted chain-of-thought reasoning in large reasoning models, but these gains come at high costs in labeled data while faltering on harder tasks. A natural next step is experience-driven learning, where models improve without curated labels by ada…

Think Then Embed: Generative Context Improves Multimodal Embedding

ICLR 2026poster

There is a growing interest in Universal Multimodal Embeddings (UME), where models are required to generate task-specific representations. While recent studies show that Multimodal Large Language Models (MLLMs) perform well on such tasks, they treat MLLMs solely as encoders, overlooking their genera…

CompCap: Improving Multimodal Large Language Models with Composite Captions

ICCV 2025poster

How well can Multimodal Large Language Models (MLLMs) understand composite images? Composite images (CIs) are synthetic visuals created by merging multiple visual elements, such as charts, posters, or screenshots, rather than being captured directly by a camera. While CIs are prevalent in real-world…
