FACTORIZATION MACHINE

Factorization Machine implementation in tensorflow 1.12.0.
Use the reference training code on-the-fly using the following command:

#--------------------------how to train----------------------------#
./train.sh <training_path> <validation_path> <save_model_dir> <batch_size> <embedding_size> \
           <optimizer [adagrad, adam]> <lr> <task [finish, like]> <track [1, 2]>

BASELINE

Our baseline results with 5 features (user_id, user_city, item_id，author_id，item_city):

• TRACK2 LIKE TASK:

  auc: 86.5% 
  #------------------------params-------------------------#
  embedding_size = 40
  optimizer = adam  
  lr = 0.0005

• TRACK FINISH TASK:

  auc: 69.8% 
  #------------------------params-------------------------#
  embedding_size = 40
  optimizer = adam   
  lr = 0.0001
