Code-MUE: Measuring Code LLMs' Uncertainty through Execution-based Semantic Interaction Graphs

This work introduces Code-MUE, a purely black-box framework that measures uncertainty through execution-based Semantic Interaction Graphs, and grounds uncertainty in observable runtime behavior, calculating the Von Neumann entropy of the solution space to quantify global semantic diversity.
