New policy guides AI simulators with real-world experiments

Researchers have developed a new policy called Fisher-SEP to help planners decide when to supplement simulators with real-world experiments. The policy decomposes the simulator's value error into identifiable calibration shifts and unresolvable parametric residuals. It also distinguishes between local and reachability components of the value gap between simulator-optimal and true optimal policies. Two case studies demonstrate Fisher-SEP's effectiveness in optimizing experimental strategies for supply chains and public health interventions. AI

    Mind the Sim-to-Real Gap & Think Like a Scientist

    Suppose a planner has a pre-trained simulator of a sequential decision problem and the option to run real experiments in the field. The simulator is cheap to query but inherits confounding and drift from its calibration data. Experimentation is unbiased but consumes one real unit…
