DenseFeatures - LostTech.TensorFlow Documentation

Type DenseFeatures

Namespace tensorflow.keras.layers

A layer that produces a dense `Tensor` based on given `feature_columns`.

Generally a single example in training data is described with FeatureColumns. At the first layer of the model, this column oriented data should be converted to a single `Tensor`.

This layer can be called multiple times with different features.

This is the V1 version of this layer that uses variable_scope's to create variables which works well with PartitionedVariables. Variable scopes are deprecated in V2, so the V2 version uses name_scopes instead. But currently that lacks support for partitioned variables. Use this if you need partitioned variables.

Example:

Show Example

price = numeric_column('price')
            keywords_embedded = embedding_column(
                categorical_column_with_hash_bucket("keywords", 10K), dimensions=16)
            columns = [price, keywords_embedded,...]
            feature_layer = DenseFeatures(columns)  features = tf.io.parse_example(..., features=make_parse_example_spec(columns))
dense_tensor = feature_layer(features)
for units in [128, 64, 32]:
  dense_tensor = tf.compat.v1.keras.layers.Dense(
                     units, activation='relu')(dense_tensor)
prediction = tf.compat.v1.keras.layers.Dense(1)(dense_tensor)
