The BucketizedColumn(fc,boundaries) command creates a new feature column by assigning continuous data represented in fc into a discrete number of buckets defined by boundaries.

This function is part of the DeepLearning package, so it can be used in the short form BucketizedColumn(..) only after executing the command with(DeepLearning). However, it can always be accessed through the long form of the command by using DeepLearning[BucketizedColumn](..).

The implementation of BucketizedColumn uses the tf.feature_column.bucketized_column function from the TensorFlow Python API Documentation. Consult the TensorFlow API documentation for tf.feature_column.bucketized_column for more information.

$\mathrm{fc}≔\mathrm{NumericColumn}\left(''PetalLength''\,\mathrm{shape}=\left[1\right]\,\mathrm{datatype}=\mathrm{float}\left[8\right]\right)$

$\mathrm{fc}≔\left[\begin{array}{c}\mathrm{Feature\; Column}\\ \mathrm{NumericColumn(key=\text{'}PetalLength\text{'},\; shape=(1,),\; default\_value=None,\; dtype=tf.float64,\; normalizer\_fn=None)}\end{array}\right]$

$\mathrm{bc}≔\mathrm{BucketizedColumn}\left(\mathrm{fc}\,\left[2\,3.5\,5\,6.5\right]\right)$

$\mathrm{bc}≔\left[\begin{array}{c}\mathrm{Feature\; Column}\\ \mathrm{BucketizedColumn(source\_column=NumericColumn(key=\text{'}PetalLength\text{'},\; shape=(1,),\; default\_value=None,\; dtype=tf.float64,\; normalizer\_fn=None),\; boundaries=(2,\; 3.5,\; 5,\; 6.5))}\end{array}\right]$

The DeepLearning[BucketizedColumn] command was introduced in Maple 2018.
