Visualize biological database for protein is very complicated without Classify the protein properties.Protein classification is one of the major application of machine learning algorithms in the field of bio-informatics.The searching classification model works in two steps.Firstly, the correlation based feature selection for protein classification will be taken and strongly correlated features will be considered for classification using MST based . In second step, using Robust Regression, the classification will be performed. Based on results of RRC algorithm, it is highly has classification ratio than traditional machine learning algorithms such as SVM, Na�ve-bayes , Decision Trees
