Classification performance is improved as the feature selection progresses. MCC (Matthew's Correlation Coefficient) increases as the number of selected features increases and reaches its maximum when 10 features are selected. The MCC remains unchanged when 11th and 12th features are selected. When more than 12 features are selected, the MCC slightly decreases.
