Zusammenfassung (Abstract) :

Online planning under uncertainty on robots and similar agents has very strict performance requirements in order to achieve reasonable behavior in complex domains with limited re- sources. The underlying process of decision- making and information gathering is correctly modeled by POMDP’s, but their complexity makes many interesting and challenging prob- lems virtually intractable. We address this is- sue by introducing a method to estimate rel- evance values for elements of a planning do- main, that allow an agent to focus on promis- ing features. This approach reduces the ef- fective dimensionality of problems, allowing an agent to plan faster and collect higher re- wards. Experimental validation was performed on two challenging POMDP’s that resemble real-world robotic task planning, where it is crucial to interleave planning and acting in an efficient manner.
