X_train |
A Matrix of trainning observations. |
Y_train |
A numeric vector of classes or values of the trainning observations. |
X_test |
A Matrix of testing observations. |
degree |
A integer that represents the kernel polynomial degree |
gamma |
A numeric value as the kernel coefficient. |
coef0 |
A numeric value for kernel independent term. |
