Efficient Pretraining Data Selection for Language Models via Multi-Actor Collaboration

ACL 2025long

Efficient data selection is crucial to accelerate the pretraining of language model (LMs). While various methods have been proposed to enhance data efficiency, limited research has addressed the inherent conflicts between these approaches to achieve optimal data selection for LM pretraining. To tack…

Hallucination at a Glance: Controlled Visual Edits and Fine-Grained Multimodal Learning

NeurIPS 2025poster

Multimodal large language models (MLLMs) have achieved strong performance on vision-language tasks but still struggle with fine-grained visual differences, leading to hallucinations or missed semantic shifts. We attribute this to limitations in both training data and learning objectives. To address…

Multi-step Visual Reasoning with Visual Tokens Scaling and Verification

NeurIPS 2025poster

Multi-modal large language models (MLLMs) have achieved remarkable capabilities by integrating visual perception with language understanding, enabling applications such as image-grounded dialogue, visual question answering, and scientific analysis. However, most MLLMs adopt a static inference paradi…
