Issue description

Hi, I am using a SupportVectorMachine model type Cauchy. The model was created with a minimum value to predict is zero, but running some scenarios the result of the prediction is a negative value. Question is, a model with SVM can extrapolate the prediction?

Hi, in theory it is more likely to happen with imbalanced dataset while introducing new unseen data to the model. Even when Cauchy doesn't depend on variance that much if I'm not mistaken. I would try some combination of kernels as it is the most common way and active learning. But of course it depends on what's your goal. And yeah.. I'm very new in this area and undereducated, so please take my thoughts very lightly.
