Validating training data of classifiers

Abstract:

A method, a computer program product, and a computer system for evaluation and modification of training data for classifiers. A computer system applies an each piece of training data of an each class to multiple classifiers. The computer system performs evaluation and validation of the training data for the each class and defines at least one representative class for the each piece of the training data of the each class if classification precision of the each piece of the training data is greater than a predetermined threshold. The computer system modifies the training data, based on results of the evaluation and the validation of the training data for the each class. The computer system performs evaluation and validation of the training data for representative classes. The computer system modifies the training data, based on results of the evaluation and the validation of the training data for the representative classes.
