- - ### Uses of StackedModel in org.apache.ignite.ml.composition.stacking

    Methods in org.apache.ignite.ml.composition.stacking that return StackedModel
    Modifier and Type | Method and Description
    --- | ---
    `<K,V> StackedModel<IS,IA,O,AM>` | StackedDatasetTrainer.`fitWithInitializedDeployingContext(DatasetBuilder<K,V> datasetBuilder, Preprocessor<K,V> preprocessor)` Trains model based on the specified data.
    `<K,V> StackedModel<IS,IA,O,AM>` | StackedDatasetTrainer.`update(StackedModel<IS,IA,O,AM> mdl, DatasetBuilder<K,V> datasetBuilder, Preprocessor<K,V> preprocessor)` Gets state of model in arguments, compare it with training parameters of trainer and if they are fit then trainer updates model in according to new data and return new model.
    `protected <K,V> StackedModel<IS,IA,O,AM>` | StackedDatasetTrainer.`updateModel(StackedModel<IS,IA,O,AM> mdl, DatasetBuilder<K,V> datasetBuilder, Preprocessor<K,V> preprocessor)` This method is never called, instead of constructing logic of update from `DatasetTrainer.isUpdateable(IgniteModel)` and `DatasetTrainer.updateModel(IgniteModel, DatasetBuilder, Preprocessor)` in this class we explicitly override update method.

    Methods in org.apache.ignite.ml.composition.stacking with parameters of type StackedModel
    Modifier and Type | Method and Description
    --- | ---
    `boolean` | StackedDatasetTrainer.`isUpdateable(StackedModel<IS,IA,O,AM> mdl)` This method is never called, instead of constructing logic of update from `DatasetTrainer.isUpdateable(M)` and `DatasetTrainer.updateModel(M, org.apache.ignite.ml.dataset.DatasetBuilder<K, V>, org.apache.ignite.ml.preprocessing.Preprocessor<K, V>)` in this class we explicitly override update method.
    `<K,V> StackedModel<IS,IA,O,AM>` | StackedDatasetTrainer.`update(StackedModel<IS,IA,O,AM> mdl, DatasetBuilder<K,V> datasetBuilder, Preprocessor<K,V> preprocessor)` Gets state of model in arguments, compare it with training parameters of trainer and if they are fit then trainer updates model in according to new data and return new model.
    `protected <K,V> StackedModel<IS,IA,O,AM>` | StackedDatasetTrainer.`updateModel(StackedModel<IS,IA,O,AM> mdl, DatasetBuilder<K,V> datasetBuilder, Preprocessor<K,V> preprocessor)` This method is never called, instead of constructing logic of update from `DatasetTrainer.isUpdateable(IgniteModel)` and `DatasetTrainer.updateModel(IgniteModel, DatasetBuilder, Preprocessor)` in this class we explicitly override update method.
