Reasoning with Uncertainty . A page of links to reference material, people, research groups, organizations, journals, books, software, conferences, companies and much more. Probabilistic Thinking . The probabilistic framework didn't exist until those people cobbled it together. It remains in use today, much as in Huygens's book.
Medicine is replete with uncertainty.
In particular, there is uncertainty due to incomplete and inexact scientific models of human health and disease, and there is uncertainty secondary to incomplete and erroneous data about individual patients. We are exploring the use of probability theory as a representation of uncertainty in medical diagnostic systems. SRI pioneered evidential reasoning for drawing conclusions from multiple sources of evidential information about dynamic real-world situations. In addition to an overview, you'll find lots of links to the technologies involved and the related applications.
