WebThe base Tuner class is the class that manages the hyperparameter search process, including model creation, training, and evaluation. For each trial, a Tuner receives new hyperparameter values from an Oracle instance. 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.
