What is the OpenCV svm type parameter

Question

The opencv SVM implementation takes a parameter labeled as "SVM type" which must be used in the CVSVMParams structure used in training the SVM. All the explanation I can find is:

// SVM type
enum { C_SVC=100, NU_SVC=101, ONE_CLASS=102, EPS_SVR=103, NU_SVR=104 };

Anyone know what these different values represent?

Answer 1

In general:

• Classification SVM Type 1 (also known as C-SVM classification)
• Classification SVM Type 2 (also known as nu-SVM classification)
• Regression SVM Type 1 (also known as epsilon-SVM regression)
• Regression SVM Type 2 (also known as nu-SVM regression)
