Hierarchical Multi-sensors Data Fusion for Enhanced Context Inference
Jeong-Bong You · International Journal of Control and Automation · 2014
Dempster-Shafer Evidence Theory can infer the context only with some native sensed signals but its number of assumptions is limited, compared to the number of evidence.In this research, we proposed a method that can increase the number of sensors collecting symptoms for more dynamic contextual inference yet with reduced calculation load increase.This is possible by clustering sensors with relevance to a situation and fusing data hierarchically.
