@pplonski How about explicit parameter to set categorical features?

@pplonski Sample weights are the most preferred way because they allow us to manipulate object importance. Some binary/multi-class datasets also require rolling fading (based on the time), and it's possible...

@pplonski There is also a cases where combination of undersampling and oversampling could be used But still don't want to have this in the first prototype It will be okay?...
