The Signal Loss Advisor-a knowledge-based command decision aid
Roland Pease, Judith Proffitt · 1993
Describes the design and development efforts associated with the Signal Loss Advisor (SLA). SLA is a command decision aid that is used to diagnose the cause for loss of an acoustic signal. The system utilizes several AI technologies. SLA has been implemented in a blackboard architecture. Within that architecture, there are two components which make the most significant contribution to the signal loss analysis problem. They correspond to steps in the signal loss analysis process. The first component is a set of rule based knowledge sources which transform low level data into evidence or qualitative descriptions of that data. The second component is a degree of belief matrix based on which transforms evidence into a diagnosis.>
