Learning by experimentation: The operator refinement method

Abstract

Autonomous systems require the ability to plan effective courses of action under potentially uncertain or unpredictable contingencies. Planning requires knowledge of the environment that is accurate enough to allow reasoning about actions. If the environment is too complex or very dynamic, goal-driven learning with reactive feedback becomes a necessity. This chapter addresses the issue of learning by experimentation as an integral component of PRODIGY.PRODIGY is a flexible planning system that encodes its domain knowledge as declarative operators and applies the operator refinement method to acquire additional preconditions or postconditions when observed consequences diverge from internal expectations. When multiple explanations for the observed divergence are consistent with the existing domain knowledge, experiments to discriminate among these explanations are generated. The …
