In this chapter we consider the implementation of feature selection approaches within the Conformal Predictor framework. We begin with a review of feature selection, then consider several approaches to implementation. First, we use existing feature selection methods within conformal predictors, which raises some computational issues. Second, we use techniques specifically designed for conformal predictors: (1) the strangeness minimization feature selection (SMFS) method and (2) the average confidence maximization (ACM) method. SMFS minimizes the overall nonconformity values of a sequence of examples, whereas ACM maximizes the average confidence output by the conformal predictor using a subset of features. We also give some results and illustrations based on a medical dataset for abdominal pain diagnosis collected in a Scottish hospital.
