process-level evaluation
Evaluating how models approach problems by focusing on intermediate steps rather than final answers. It checks subgoal completion, reasoning chains, or evidence intervals, providing granular feedback. This reveals specific failures, like compositional errors or irrelevant actions, that outcome-based metrics hide.
The papers find that outcome-level feedback can effectively shape process evaluation, reducing reliance on expensive step annotations. Process evaluation uncovers distinct failure types across models, aiding targeted improvements. Benchmarks that require assessing intermediate steps highlight these detailed errors, making evaluation more useful for guiding development.
