Implementation of Hyperband: a novel bandit based approach to hyper-parameter optimization https://arxiv.org/abs/1603.06560
- def evaluate_hparams(hparams, nb_epochs):
# evaluate an hyper-parameter configuration and return a loss value and some additional information # e.g., result report return 0.0, {}
- _repeat_one(self, result_path, hyper_parameters, repeat_id, nb_runs)¶
Run full Hyperband search :param result_path: :return: the last round of configurations
- optimize(self, result_path)¶
Optimize the hyper parameters using Hyperband
- Parameters
result_path – where to save the information of each run. Can be None, in this case nothing is exported.
- Returns
the results of all the runs
