About KerasTuner
KerasTuner is an open-source hyperparameter optimization framework for Keras machine learning models. It simplifies hyperparameter search by letting users define search spaces with a define-by-run syntax, then uses built-in algorithms to identify optimal hyperparameter values for their models. The framework includes pre-built Bayesian Optimization, Hyperband, and Random Search algorithms, and is designed to be easily extended by researchers developing new search methods. It requires Python 3.8+ and TensorFlow 2.0+, and is installable via pip.
