Instantiates the Operation-aware Neural Networks architecture.

Parameters:
  • linear_feature_columns – An iterable containing all the features used by linear part of the model.
  • dnn_feature_columns – An iterable containing all the features used by deep part of the model.
  • embedding_size – positive integer,sparse feature embedding_size
  • dnn_hidden_units – list,list of positive integer or empty list, the layer number and units in each layer of deep net
  • l2_reg_embedding – float. L2 regularizer strength applied to embedding vector
  • l2_reg_linear – float. L2 regularizer strength applied to linear part.
  • l2_reg_dnn – float . L2 regularizer strength applied to DNN
  • init_std – float,to use as the initialize std of embedding vector
  • seed – integer ,to use as random seed.
  • dnn_dropout – float in [0,1), the probability we will drop out a given DNN coordinate.
  • use_bn – bool,whether use bn after ffm out or not
  • reduce_sum – bool,whether apply reduce_sum on cross vector
  • task – str, "binary" for binary logloss or "regression" for regression loss
Returns:

A Keras model instance.
