steps: Steps for feature columns specification.

In rstudio/tfdatasets: Interface to 'TensorFlow' Datasets

Steps for feature columns specification.

Description

List of steps that can be used to specify columns in the feature_spec interface.

Steps

• step_numeric_column() to define numeric columns.

• step_categorical_column_with_vocabulary_list() to define categorical columns.

• step_categorical_column_with_hash_bucket() to define categorical columns where ids are set by hashing.

• step_categorical_column_with_identity() to define categorical columns represented by integers in the range ⁠[0-num_buckets)⁠.

• step_categorical_column_with_vocabulary_file() to define categorical columns when their vocabulary is available in a file.

• step_indicator_column() to create indicator columns from categorical columns.

• step_embedding_column() to create embeddings columns from categorical columns.

• step_bucketized_column() to create bucketized columns from numeric columns.

• step_crossed_column() to perform crosses of categorical columns.

• step_shared_embeddings_column() to share embeddings between a list of categorical columns.

• step_remove_column() to remove columns from the specification.
