The ALARM Monitor and the Bone-Marrow Transplant Therapy Advisor: A Demonstration of Two Probabilistic Expert Systems in KNET

ALARM (A Logical Alarm Reduction Mechanism) is a diagnostic application used to explore probabilistic reasoning techniques in belief networks. ALARM implements an alarm message system for patient monitoring; it calculates probabilities for a differential diagnosis based on available evidence [1]. The medical knowledge is encoded in a graphical structure connecting 8 diagnoses, 16 findings and 13 intermediate variables.
