normally in svm how are the trai= ning data classified in 1/0 class label?

In 1/-1 classification we will be checking sign(decision function) ie , if = the calculated decision function value is negative we will give -1 classlab= el and if it is positive we will give 1 as class label.

After finding that we will compare the class label with the class label of = input data...and find the accuracy/miss classification.

What about = in 1/0 classification???

Do we have an SVM implementation?
