Refusal Tokens: A Simple Way to Calibrate Refusals in Large Language Models

no code implementations9 Dec 2024 Neel Jain, Aditya Shrivastava, Chenyang Zhu, Daben Liu, Alfy Samuel, Ashwinee Panda, Anoop Kumar, Micah Goldblum, Tom Goldstein

A key component of building safe and reliable language models is enabling the models to appropriately refuse to follow certain instructions or answer certain questions.

Retrieval Augmented Correction of Named Entity Speech Recognition Errors

no code implementations9 Sep 2024 Ernest Pusateri, Anmol Walia, Anirudh Kashi, Bortik Bandyopadhyay, Nadia Hyder, Sayantan Mahinder, Raviteja Anantha, Daben Liu, Sashank Gondala

In recent years, end-to-end automatic speech recognition (ASR) systems have proven themselves remarkably accurate and performant, but these systems still have a significant error rate for entity names which appear infrequently in their training data.
