We describe the desire for a black box approach to pattern classification: a generic Autonomous Pattern Recognizer, which is capable of self-adapting to specific alphabets without human intervention. The CellNet software system is introduced, an evolutionary system that optimizes a set of pattern-recognizing agents relative to a provided set of features and a given pattern database. CellNet utilizes a new genetic operator designed to facilitate a canalization of development: Merger. CellNet… 

CellNet CoEv : Co-Evolving Robust Pattern Recognizers

An evolutionary model of classifier synthesis is presented. The CellNet system for generating binary pattern classifiers is used as a base for experimentation [5]. CellNet is extended to include a

CellNet Co-Ev: Evolving Better Pattern Recognizers Using Competitive Co-evolution

The CellNet system for generating binary classifiers is extended to include a competitive co- evolutionary Genetic Algorithm, where patterns evolve as well as classifiers; This is facilitated by the addition of a set of topologically-invariant camouflage functions, through which images may disguise themselves.

Using Competitive Co-evolution to Evolve Better Pattern Recognisers

Application to the CEDAR database of handwritten characters shows an increase in the reliability of the evolution of recognisers, as well as in the elimination of over-fitting, relative to the original CellNet software.

Evolving novel image features using Genetic Programming-based image transforms

The notion of a Transform-based Evolvable Feature (TEF), a moment value extracted from a GP-transformed image, used in a classification task, and it is shown that the inclusion of a single TEF allows for significantly superior classification relative to predefined features alone.

A Coevolution Algorithm in the Image Recognition System

Fast generic selection of features for neural network classifiers

The authors describe experiments using a genetic algorithm for feature selection in the context of neural network classifiers, specifically, counterpropagation networks, and propose a method called the training set sampling, which selects feature sets that are as good as and occasionally better for counterPropagation than those chosen by an evaluation that uses the entire training set.
