Abstract

In this paper, a knowledge discovery framework is used for protein classification. The processing is achieved in three steps: feature extraction, feature ranking and feature selection. Inspirited from text mining results for the first step, we use n-grams descriptors; descriptors are ranked from chi-2 statistical indices in the second step; and in the final step, the subset of descriptors is selected which will minimize the prediction error rate using a k-nearest neighbor classifier. Experiments show that this framework gives good results: the dimensionality reduction is effective and increases the classifier performances.
