This paper describes the Entropy Reduction Engine, an architecture for the integration of planning, scheduling, and control. The architecture is motivated, presented, and analyzed in terms of its different components; namely, problem reduction, temporal projection, and situated control rule execution. Experience with this architecture has motivated the… (More)
We describe Ask How It Works, a prototype interactive intelligent manual for devices, based on novel intelligent training systems called ASK Systems.
Conceptual information retrieval systems use structured document indices, domain knowledge and a set of heuristic retrieval strategies to match user queries with a set of indices describing the document's content. Such retrieval strategies increase the set of relevant documents retrieved (increase recall), but at the expense of returning additional… (More)
We describe Deja Vu, a video retrieval system which capitalizes on our understanding of the content of the video to provide an effective user interface.
