Chain-of-Retrieval Augmented Generation

Liang Wang, Haonan Chen, Nan Yang +3

This paper introduces an approach for training o1-like RAG models that retrieve and reason over relevant information step by step before generating the final answer. Conventional R…

MoCa: Modality-aware Continual Pre-training Makes Better Bidirectional Multimodal Embeddings

Haonan Chen, Hong Liu, Yuping Luo +4

Multimodal embedding models, built upon causal Vision Language Models (VLMs), have shown promise in various tasks. However, current approaches face three key limitations: the use o…

Generative Representational Instruction Tuning

Niklas Muennighoff, Hongjin Su, Liang Wang +5

All text-based language problems can be reduced to either generation or embedding. Current models only perform well at one or the other. We introduce generative representational in…

LongEmbed: Extending Embedding Models for Long Context Retrieval

Dawei Zhu, Liang Wang, Nan Yang +4

Embedding models play a pivot role in modern NLP applications such as IR and RAG. While the context limit of LLMs has been pushed beyond 1 million tokens, embedding models are stil…
