Keras tuner bayesian optimization example
Web10 mrt. 2024 · The random search algorithm requires more processing time than hyperband and Bayesian optimization but guarantees optimal results. In our experiment, hyperparameter optimization was provided by using Keras Tuner with the random search algorithm for both models. Parameters are given in Table 1, which were used for … WebIt is optional when Tuner.run_trial() is overriden and does not use self.hypermodel. objective: A string, keras_tuner.Objective instance, or a list of keras_tuner.Objectives and strings. If a string, the direction of the optimization (min or max) will be inferred.
