LLM Uncertainty Quantification: Blackbox vs. Whitebox Methods Compared

Researchers are exploring methods for Large Language Models (LLMs) to quantify their own uncertainties, a capability crucial for applications like active learning and safety classification. Current approaches are divided into 'whitebox' methods, which analyze internal model states but require access to model weights, and 'blackbox' methods, which rely on observable outputs like tokens and their probabilities. A recent comparison evaluated eight blackbox techniques against one whitebox method to determine the most effective approach for LLM confidence estimation. AI

IMPACT Improved LLM reliability and interpretability could enhance their use in critical applications.
