TL;DR: Unlike in language generation where multiple equally-acceptable outputs exist, each doc in GR is associated with a unique ID. If you miss one DocID token in beam search, you cannot recover. Solution: plan ahead in GR decoding! #SIGIR2024

TL;DR: Generate diverse synthetic data for your domain-specific task-oriented dialogue system using LLMs by doing random walk over the state transition graph. This will lead to a substantial performance boost.

Wondering how to evaluate the retrieval quality in RAG pipelines? check this out! TL;DR: evaluating based on the passages that contain groundtruth answers or KILT's provenance labels has low correlations with end-to-end RAG performance. Try "pip install erag" instead! #SIGIR2024
