Hierarchical classification: its usefulness for diagnosis and sensor validation

The concept of the generic task, one of a small set of ubiquitous cognitive tasks that together account for some part of human cognition, is examined. In particular, how hierarchical classification is one such generic task and how it is useful for diagnosis is shown. It is also shown that a diagnosis system based on hierarchical classification naturally lends itself to solving a number of issues traditionally associated with sensor validation is examined
