METHOD AND SYSTEM FOR ASSISTING USERS IN AN AUTOMATED DECISION-MAKING ENVIRONMENT

摘要

A system and method guide the modification of an input feature vector to an automatic classifier model to cause the classifier to give a desired class without modifying the classifier. A user defines costs for independently modifying feature values for at least some of the features in an initial feature vector that the classifier model has given an undesired class. Subspaces are identified in a feature space in which the classifier model classifies feature vectors in the desired class. With a cost function which takes into account the user-defined costs, a modified feature vector is identified in one of the identified subspaces which optimizes the cost function. The modified feature vector or information based thereon is output.
