Certain estimators that implement the Online interface can be trained in batches. Estimators of this type are great for when you either have a continuous stream of data or a dataset that is too large to fit into memory. Partial training allows the model to evolve as new data is acquired.

Partially Train#

To partially train an online learner:

public partial(Dataset $dataset) : void


$folds = $dataset->fold(3);




Note: Learner will continue to train as long as you are using the partial() method, however, calling train() on a trained or partially trained learner will reset it back to baseline first.
