Interval Discretizer#
This transformer creates an equi-width histogram for each continuous feature column and encodes a discrete category with an automatic bin label for each continuous feature column. The Interval Discretizer is useful when converting continuous features to categorical features so they can be learned by an estimator that supports categorical features natively.
Interfaces: Transformer, Stateful
Data Type Compatibility: Continuous
Parameters#
| # | Param | Default | Type | Description |
|---|---|---|---|---|
| 1 | bins | 5 | int | The number of bins (discrete categories) per continuous feature column. |
Additional Methods#
Return the possible categories of each feature column:
public categories() : array
Return the intervals of each continuous feature column calculated during fitting:
public intervals() : array
Example#
use Rubix\ML\Transformers\IntervalDiscretizer;
$transformer = new IntervalDiscretizer(10);
