Decompositional model-based learning and its analogy to diagnosis
A new generation of sensor rich, massively distributed autonomous system is being developed, such as smart buildings and recongurable factories. To achieve high performance these systems will need to accurately model themselves and their environment from sensor information. Accomplishing this on a g...

A new generation of sensor rich, massively distributed autonomous system is being developed, such as smart buildings and recongurable factories. To achieve high performance these systems will need to accurately model themselves and their environment from sensor information. Accomplishing this on a grand scale re-quires automating the art of large-scale modeling. To this end we have developed decompositional, model-based learning (DML). DML takes a parameterized model and sensed variables as input, decomposes it, and synthesizes a coordinated sequence of \simplest" estimation tasks. The method exploits a rich analogy between parameter estimation and consistency-based diagnosis. Moriarty, an implementation of DML, has been applied to thermal modeling of a smart building, demonstrating a signicant improvement in learning rate. A new generation of sensor rich, massively dis-tributed, autonomous systems is being developed, such as networked building energy systems, autonomous space probes, and biosphere-like life support systems, that have the potential for profound environmental and economic change (Williams & Nayak 1996).
