Yes, there are various methods for optimizing neural network hyperparameters automatically. One such method is called grid search, where you define a range of values for each hyperparameter and the algorithm tests all possible combinations to find the optimal set of hyperparameters. Another method is called random search, where the algorithm randomly samples hyperparameters from a given distribution to find the optimal combination.

More advanced techniques include Bayesian optimization, which builds a probabilistic model of the objective function and uses it to make informed decisions about which hyperparameters to try next. Another popular method is called evolutionary algorithms, which are inspired by biological evolution and use genetic operators such as mutation and crossover to optimize the hyperparameters.

There are also many machine learning libraries that have built-in functionality for hyperparameter optimization, such as Keras Tuner, scikit-optimize, and Optuna. These libraries allow you to define a search space for the hyperparameters, and they will automatically try different combinations until the optimal set is found.

Overall, there are many ways to automate the process of finding the optimal hyperparameters for your neural network. These methods can save time and effort compared to manually adjusting the hyperparameters and observing results.
