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.
To partially train an online learner:
public partial(Dataset $dataset) : void
$folds = $dataset->fold(3); $estimator->train($folds); $estimator->partial($folds); $estimator->partial($folds);
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.
