The Robot Asked Whether Information Was Worth the Risk
Changing only the path-value objective shifted simulated explorers between informative danger and safer future sensing.
Summary
Changing only the path-value objective shifted simulated explorers between informative danger and safer future sensing.
A hazardous explorer can lose the chance to learn later if an informative path destroys it now. The study held the belief update, sensor, physical-risk model and finite-horizon planner fixed, then changed only the scalar used to value feasible paths. A Prelec-weighted behavioral-information objective created interpretable conservative-to-aggressive regimes and switching boundaries along the information–risk frontier. In failure-truncated grid worlds, risk-aware valuations reduced hazard exposure and robot losses, while plain Shannon information remained a strong raw-information baseline. Physical validation remains to be shown.
