Prediction performance of SVM models used in SSPred
The SVM Models were developed using SVM-light package utilizing fixed length vector derived from amino-acid, dipeptide composition, physico-chemical properties, hyrbid-I and hybrid-II based input features. The performance of the trained modules was measured in terms of Mathew Correlation Coefficient (MCC) and was evaluated using 5-fold cross validation and validation test. |
