Assigning Measurement Effort to a Value-Aware Evidence Search
Abstract
Value-aware model learning and knowledge-graph path search can emphasize different evidence. Evaluation should retain the paths selected and the state-action regions emphasized by the policy. It then independently checks the terminal action and counts search assessment costs. A favorable global fit or large expansion count is incomplete evidence for a useful value-directed workflow. This focused synthesis develops an empirical comparison that preserves the terminal action, observation process, and total verification cost. Its proposed tests are prospective; no new simulation run, model-training result, or intervention effect is reported.
