Classes are integer used as output of the function (instead of having -1,1 as class values).

Parameters

  • S – [in] Parameters for the SVM function

  • nbOfSupportVectors – [in] Number of support vectors

  • vectorDimension – [in] Dimension of vector space

  • intercept – [in] Intercept

  • dualCoefficients – [in] Array of dual coefficients

  • supportVectors – [in] Array of support vectors

  • classes – [in] Array of 2 classes ID
