RLVE: Scaling Up Reinforcement Learning for Language Models with Adaptive Verifiable Environments

Zhiyuan Zeng, Hamish Ivison, Yiping Wang +14

We introduce Reinforcement Learning (RL) with Adaptive Verifiable Environments (RLVE), an approach using verifiable environments that procedurally generate problems and provide alg…

PrefDisco: Benchmarking Proactive Personalized Reasoning

Shuyue Stella Li, Avinandan Bose, Faeze Brahman +4

Current large language model (LLM) development treats task-solving and preference-alignment as separate challenges, optimizing first for objective correctness, then for alignment t…

Spurious Rewards: Rethinking Training Signals in RLVR

Rulin Shao, Shuyue Stella Li, Rui Xin +11

We show that reinforcement learning with verifiable rewards (RLVR) can elicit strong mathematical reasoning in certain language models even with spurious rewards that have little,…

Understanding the Gain from Data Filtering in Multimodal Contrastive Learning

Divyansh Pareek, Sewoong Oh, Simon S. Du

The success of modern multimodal representation learning relies on internet-scale datasets. Due to the low quality of a large fraction of raw web data, data curation has become a c…

Highlighting What Matters: Promptable Embeddings for Attribute-Focused Image Retrieval

Siting Li, Xiang Gao, Simon Shaolei Du

While an image is worth more than a thousand words, only a few provide crucial information for a given task and thus should be focused on. In light of this, ideal text-to-image (T2…

Exploring How Generative MLLMs Perceive More Than CLIP with the Same Vision Encoder

Siting Li, Pang Wei Koh, Simon Shaolei Du

Recent research has shown that CLIP models struggle with visual reasoning tasks that require grounding compositionality, understanding spatial relationships, or capturing fine-grai…
