Parameters

 -do-not-check-capabilities If set, classifier capabilities are not checked before classifier is built (use with caution). B Generate probability estimates for classification C Set the parameter C of C-SVC, epsilon-SVR, and nu-SVR (default: 1) default: 1.0 D Set degree in kernel function (default: 3) default: 3 E Set tolerance of termination criterion (default: 0.001) default: 0.001 G Set gamma in kernel function (default: 1/k) default: 0.0 H Turns the shrinking heuristics off (default: on) J Turn off nominal to binary conversion. WARNING: use only if your data is all numeric! K Set type of kernel function (default: 2) 0 = linear: u'*v 1 = polynomial: (gamma*u'*v + coef0)^degree 2 = radial basis function: exp(-gamma*|u-v|^2) 3 = sigmoid: tanh(gamma*u'*v + coef0) default: 2 M Set cache memory size in MB (default: 40) default: 40.0 N Set the parameter nu of nu-SVC, one-class SVM, and nu-SVR (default: 0.5) default: 0.5 P Set the epsilon in loss function of epsilon-SVR (default: 0.1) default: 0.1 R Set coef0 in kernel function (default: 0) default: 0.0 S Set type of SVM (default: 0) 0 = C-SVC 1 = nu-SVC 2 = one-class SVM 3 = epsilon-SVR 4 = nu-SVR default: 0 V Turn off missing value replacement. WARNING: use only if your data has no missing values. W Set the parameters C of class i to weight[i]*C, for C-SVC. E.g., for a 3-class problem, you could use "1 1 1" for equally weighted classes. (default: 1 for all classes) Z Turns on normalization of input data (default: off) model Specifies the filename to save the libsvm-internal model to. Gets ignored if a directory is provided. default: /Users/joa/Downloads/weka-3-7-12 output-debug-info If set, classifier is run in debug mode and may output additional info to the console seed Random seed (default = 1) default: 1
