HPOflow - Sphinx DOC

Tools for Optuna, MLflow and the integration of both.

This project is maintained by the One Conversation team of Deutsche Telekom AG.

The main components are:

• hpoflow.optuna_mlflow.OptunaMLflow:
  A wrapper to use Optuna and log to MLflow at the same time.
• hpoflow.optuna_transformers.OptunaMLflowCallback:
  Class inheriting from transformers.TrainerCallback that integrates with OptunaMLflow to send the logs to MLflow and Optuna during model training.
• hpoflow.optuna.SignificanceRepeatedTrainingPruner:
  An Optuna pruner to use statistical significance (a t-test which serves as a heuristic) to stop unpromising trials early, avoiding unnecessary repeated training during cross validation.
