RAFFLES: Reasoning-based Attribution of Faults for LLM Systems

Chenyang Zhu, Spencer Hong, Jingyu Wu +6

The advent of complex, interconnected long-horizon LLM systems has made it incredibly tricky to identify where and when these systems break down. Evaluation capabilities that curre…

DF-RAG: Query-Aware Diversity for Retrieval-Augmented Generation

Saadat Hasan Khan, Spencer Hong, Jingyu Wu +4

Retrieval-augmented generation (RAG) is a common technique for grounding language model outputs in domain-specific information. However, RAG is often challenged by reasoning-intens…

Harmonizing Diverse Models: A Layer-wise Merging Strategy for Consistent Generation

Xujun Peng, Anoop Kumar, Jingyu Wu +2

Retrieval-Augmented Generation (RAG) systems leverage Large Language Models (LLMs) to generate accurate and reliable responses that are grounded in retrieved context. However, LLMs…
