Apparently, I've found this implementation
https://github.com/dbtsai/spark/tree/dbtsai-mlor. It did work on my examples
producing reasonable results. Could you comment on the following? Why the
number of parameters (weights) is equal to (num_features + 1)*(num_classes-1) ?
I would expect (num_features + 1)*(num_classes) as it is here for example:
