Automatic Budget Determination for HyperBand

Im Rahmen des Projekts AutoML

Beschreibung

A well known approach for efficient automated machine learning (AutoML) is to stop the evaluation of model training when it does not look promising, e.g., by looking at learning curves of deep neural networks. One simple but robust approach is successive halving (and its extension HyperBand), which simply throws away half of the candidate models at user-defined budget points, e.g., after 4, 8, 16 and 32 epochs.

The drawback of this approach is that the users need expert knowledge to define these budget points. The task of this project is to study different techniques that learn a policy from data, automatically determining the budget points. This will further improve the usability and hopefully also the performance of well known AutoML tools, such as BOHB and SMAC.
