Therefore, how to make the automatic tuning algorithm achieve high precision and high efficiency has always been a problem that has not yet been fully solved in machine learning. Hyperparameter tuning is an optimization problem where the objective function of optimization is unknown or a black-box...
An optimizer is the process of hyperparameter tuning that updates the machine learning model after each step of weight loss adjustment of input features. The permutation and combination of high and low learning rates with various step sizes ultimately leads to an optimal tuning model. The step siz...
