Researchers have developed a novel method called EvalCEGAR to automatically generate evaluation metrics for AI agents, particularly for tasks like report generation where human scoring is difficult. This approach uses a pool of small Python operators that flag specific defects in AI-generated content. By employing counterexample-guided abstraction refinement, similar to program verification techniques, EvalCEGAR searches for pairs of AI outputs that are incorrectly scored identically by the operators. This process iteratively refines the operators to improve their accuracy and reduce the number of false positives, significantly closing the gap between random chance and perfect filtering on benchmark datasets.
