alphaFM. Multi-thread implementation of Factorization Machines with FTRL for binary-class classification problem.

alphaPLM. Multi-thread implementation of Piece-wise Linear Model(PLM) or Mixture of LR(MLR) with FTRL for binary-class classification problem.

lambdaFM. Multi-thread implementation of lambdaFM with FTRL for ranking problem. LambdaFM is a learning-to-rank algorithm by combining LambdaRank and Factorization Machines.

alphaFM_softmax. Multi-thread implementation of Factorization Machines with FTRL for multi-class classification problem which uses softmax as hypothesis.

NDCG. Python

AUC. C++
