Researchers have developed a new method called Train for Accuracy, then Post-hoc Select (TAPS) for large language models (LLMs) to improve their ability to abstain from answering questions they are uncertain about. This modular approach allows for controllable coverage and can be implemented using standard post-training techniques and existing confidence estimators. TAPS demonstrated lower mean risk compared to traditional abstention training methods across multiple LLMs and factual question-answering benchmarks. AI
IMPACT Improves LLM reliability by enabling better control over when models abstain from answering, potentially reducing hallucinations.
