Abstract: In an approach for improved artificial intelligence planning in an automated machine learning pipeline, a processor formulates an artificial intelligence planning problem. A processor receives a pre-defined stopping criterion for generating one or more plans for the artificial intelligence planning problem. A processor generates the one or more plans by executing a planning algorithm. A processor reformulates the artificial intelligence planning problem into a new artificial intelligence planning problem by forbidding plans that correspond to super-sets of the one or more plans. A processor generates one or more new plans based on the reformulation until the pre-defined stopping criterion is reached.

Abstract: A mechanism is provided for computing a solution to a plan recognition problem. The plan recognition problem includes the model and a partially ordered sequence of observations or traces. The plan recognition is transformed into an AI planning problem such that a planner can be used to compute a solution to it. The approach is general. It addresses unreliable observations: missing observations, noisy observations (or observations that need to be discarded), and ambiguous observations). The approach does not require plan libraries or a possible set of goals. A planner can find either one solution to the resulting planning problem or multiple ranked solutions, which maps to the most plausible solution to the original problem.
