Applying a Probabilistic Inference Stream Processing Engine to a Camera Sensor Network

Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this paper is to appropriately incorporate Bayesian networks into a relational stream processing
system in the form of abstract data type. To achieve it, we propose two mechanisms. The first proposal is a mechanism to
associate an input relation with an internal relation which has Bayesian networks. We refer to it as ASSOC, and show its processing
mechanism and interface as a data definition language. The second proposal is a new state management mechanism
with lifespan concept for Bayesian network operator, revising our previous work. The proposal includes counting of event sets
and event based invocation of probability propagation, which realizes appropriate event detections.
