I summarize the current design and come out with a few things that can be done to make spark-ffm better. 1. add global bias intercept and one-way interactions, current design only support pairwise interactions 2. normalization support

It'd be nice if any of you are interested in working on this project, you are always welcome and I will try best to help. :)

hello, I have used your ffm to train some model in big data, but the tr_loss turns out to be NaN when the data size is larger than 1000000, please do a favor

@VinceShieh I did not try your PR，I did some processing on the features. Next I will test your changes and then send feedback. Thank you.
