maybe add libfm and libffm to benchmark

Factorization machines (FM) are a generic approach that allows to mimic most factorization models by feature engineering.

LIBFFM is an open source tool for field-aware factorization machines (FFM). For the formulation of FFM, please see these slides. It has been used to win two recent click-through rate prediction competitions (Criteo's and Avazu's).

They are also very interesting tools.

why remove the labels? Is contribution no longer needed?

Sorry, I don't recall why I removed the labels (it was 2 yrs ago). Btw this repo is more like in legacy mode, see https://github.com/szilard/benchm-ml#summary (in short: on a reduced scope, I maintain https://github.com/szilard/GBM-perf for GBMs)
