Abstract: Feature selection is a crucial step in classification of protein sequences into existing superfamilies. Classifying protein sequences into different families based on their sequence patterns is helpful in predicting the structure and function of protein. This paper proposes a novel feature selection algorithm which first transforms the protein sequences into feature vectors and reduces the size of the feature vector based on the apriori property and correlation measure using MapReduce programming on Hadoop framework. Experimental results show that the proposed method of feature selection reduces the features by 99% and also improves accuracy by 5% to 6%.
Keywords: apriori property; sequence classification; correlation analysis; feature subset selection; MapReduce; bioinformatics.
