(linear_feature_columns, dnn_feature_columns, dnn_hidden_units=(256, 128, 64), l2_reg_embedding=1e-05, l2_reg_linear=1e-05, l2_reg_dnn=0, dnn_dropout=0, seed=1024, use_bn=True, reduce_sum=False, task='binary')[source]¶ 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.
- 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
- 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.
