Ensembles

Ensemble is just a boolean flag in our fit function. However,there are some lines of code hidden under it. Well, how do ensembles actually work? In our library, currently only blending technique is supported. Blending is an ensemble machine learning technique that uses a machine learning model to learn how to best combine the predictions from multiple contributing ensemble member models.

It takes top 3 algorithms with highest accuracy on validation data from model list. To enable ensemble, just pass ensemble=True to hana_automl.automl.AutoML.fit() function when creating AutoML model.
