Integrating learning from examples into the search for diagnostic policies

Oregon State University. Dept. of Computer Science; Bayer-Zubek, Valentina; Dietterich, Thomas Glen (Corvallis, OR : Oregon State University, Dept. of Computer Science, 2004)

This paper studies the problem of learning diagnostic policies from training examples. A diagnostic policy is a complete description of the decision-making actions of a diagnostician (i.e., tests followed by a diagnostic ...
Learning diagnostic policies from examples by systematic search

Oregon State University. Dept. of Computer Science; Zubek, Valentina Bayer (Corvallis, OR : Oregon State University, Dept. of Computer Science, 2004)

A diagnostic policy species what test to perform next based on the results of previous tests and when to stop and make a diagnosis. Cost-sensitive diagnostic policies perform tradeoffs between (a) the costs of tests and ...
Pruning improves heuristic search for cost-sensitive learning

Oregon State University. Dept. of Computer Science; Zubek, Valentina Bayer; Dietterich, Thomas Glen (Corvallis, OR : Oregon State University, Dept. of Computer Science, 2004)

This paper addresses cost-sensitive classification in the setting where there are costs for measuring each attribute as well as costs for misclassification errors. We show how to formulate this as a Markov Decision Proc ...
