KerasTuner Oracles

The Oracle class is the base class for all the search algorithms in KerasTuner. An Oracle object receives evaluation results for a model (from a Tuner class) and generates new hyperparameter values.

The built-in Oracle classes are RandomSearchOracle, BayesianOptimizationOracle, and HyperbandOracle.

You can also write your own tuning algorithm by subclassing the Oracle class.
