The Error Coding and Substitution PaCTs

A new class of plug in classification techniques have recently been developed inthe statistics and machine learning literature. A plug in classification technique(PaCT) is a method that takes a standard classifier (such as LDA or TREES) and plugs it into an algorithm to produce a new classifier. The standard classifier is known as the Plug in Classifier (PiC).These methods often produce large improvements over using a single classifier. In this paper we investigate one of these methods and give some motivation for its success.
