LLM research tackles uncertainty in function calls and system propagation

By PulseAugur Editorial · [2 sources] ·

Two new research papers explore the critical issue of uncertainty in Large Language Models (LLMs). The first paper investigates uncertainty quantification methods specifically for LLM function-calling, finding that simple single-sample methods can be effective and can be improved by analyzing output structure. The second paper addresses uncertainty propagation within complex LLM-based systems, proposing a framework to understand how errors can compound across various system components and processes. AI

IMPACT These papers highlight the need for better uncertainty management in LLM systems, crucial for reliable deployment in real-world applications.

    Uncertainty Propagation in LLM-Based Systems

    arXiv:2604.23505v1 Announce Type: cross Abstract: Uncertainty in large language model (LLM)-based systems is often studied at the level of a single model output, yet deployed LLM applications are compound systems in which uncertainty is transformed and reused across model interna…
