  2. 1. An architecture for diagnostic reasoning based on causal models

    Author : Jan Olsson; Stockholms universitet; []
    Keywords : Diagnostiska metoder; Dynamisk programmering; Expertsystem; Databehandling;

    Abstract : This thesis proposes an architecture for diagnostic reasoning employing causal models. The architecture embodies a knowledge representation at the problem-solving layer. That is, the way a problem is solved—in this case to arrive at a diagnosis—is an integral part of the knowledge representation. READ MORE

  4. 2. An Improved Belief Rule-Based Expert System with an Enhanced Learning Mechanism

    Author : Raihan Ul Islam; Karl Andersson; Mohammad Shahadat Hossain; Christian Becker; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

    Abstract : Belief rule-based expert systems (BRBESs) are widely used in various domains which provide an integrated framework to handle qualitative and quantitative data by addressing several kinds of uncertainty. The correctness of the data significantly affects the accuracy of the BRBESs. READ MORE
