Output
message ----------------------------------------------------------------------------------------------------------------------------------------- Model table is created successfully The model is trained with 120 samples and 512 unique attributes with hash projection There are 3 different classes in the training set The model is converged after 12 steps with epsilon 0.01, the average value of the loss function for the training set is 56.53662594767713 The corresponding training parameters are cost:1.0 bias:0.0
Only models with RBF and Sigmoid kernels have converged. This may mean that the true boundaries in the data set are hard to capture with a linear or polynomial model.
