HoneyBee: Data Recipes for Vision-Language Reasoners

CVPR 2026

Recent advances in vision-language models (VLMs) have made them highly effective at reasoning tasks. However, the principles underlying the construction of performant VL reasoning training datasets remain poorly understood. In this work, we introduce several data curation approaches and study their

LOFT: Scalable and More Realistic Long-Context Evaluation

NAACL 2025findings

Long-context language models (LCLMs) have the potential to revolutionize our approach to tasks traditionally reliant on external tools like retrieval systems or databases. Leveraging LCLMs’ ability to natively ingest and process entire corpora of information offers numerous advantages. It enhances u…

Re-Invoke: Tool Invocation Rewriting for Zero-Shot Tool Retrieval

EMNLP 2024finding

Recent advances in large language models (LLMs) have enabled autonomous agents with complex reasoning and task-fulfillment capabilities using a wide range of tools. However, effectively identifying the most relevant tools for a given task becomes a key bottleneck as the toolset size grows, hindering…

End-to-End Training of Multi-Document Reader and Retriever for Open-Domain Question Answering

NeurIPS 2021poster

We present an end-to-end differentiable training method for retrieval-augmented open-domain question answering systems that combine information from multiple retrieved documents when generating answers. We model retrieval decisions as latent variables over sets of relevant documents. Since marginali…
