indicator_column(categorical_column)
Defined in tensorflow/python/feature_column/feature_column.py
.
Represents multi-hot representation of given categorical column.
Used to wrap any categorical_column_*
(e.g., to feed to DNN). Use embedding_column
if the inputs are sparse.
name = indicator_column(categorical_column_with_vocabulary_list('name', ['bob', 'george', 'wanda']) columns = [name, ...] features = tf.parse_example(..., features=make_parse_example_spec(columns)) dense_tensor = input_layer(features, columns) dense_tensor == [[1, 0, 0]] # If "name" bytes_list is ["bob"] dense_tensor == [[1, 0, 1]] # If "name" bytes_list is ["bob", "wanda"] dense_tensor == [[2, 0, 0]] # If "name" bytes_list is ["bob", "bob"]
Args:
-
categorical_column
: A_CategoricalColumn
which is created bycategorical_column_with_*
orcrossed_column
functions.
Returns:
An _IndicatorColumn
