A diagnostic system that learns from experience

LiverSoar is a flexible knowledge-based system that can learn from its problem-solving experience in individual cases. Within an opportunistic abductive framework, it can diagnose liver diseases from findings in liver tissue biopsies. As more cases are encountered and more recognition knowledge is acquired, the system becomes prepared for most of the usual cases, hence solves them with less problem-solving effort. At the same time, it stays flexible enough to fall back to deliberative problem solving in more unusual cases if the acquired knowledge does not apply.
