The key parameters for the gridworld exploration example are:
- INSPECT_ACC: The probability that inspecting reveals the true target label. For this symmetric channel, values farther above chance, from toward , make inspection more informative and generally reduce the number of probes needed.
- INSPECT_COST: The reward cost charged for each observation. It determines when the one-probe task value exceeds immediate commitment.
- beta: The additional reward-per-nat weight on raw information. In this example small values leave the decision-aware policy unchanged, while large values cause avoidable extra probes.
- threshold: The information-gain cutoff used by the curious policy. Lower thresholds cause inspection on weaker evidence.
- HAZARD: The known forbidden cell used by the one-step action filter. It is not a learned or probabilistic hazard model.
