Hyperparameter tuning is the process of finding the best set of hyperparameters for a machine learning model. Hyperparameters are parameters such as learning rate, number of neurons, or the weight of connections in a neural network.
Grid search is a systematic approach to hyperparameter tuning where you systematically try out different combinations of hyperparameters. You can use grid search by hand, but it can be time-consuming and often leads to suboptimal solutions.
Random search is another systematic approach to hyperparameter tuning where you randomly select a subset of the possible hyperparameter values. Random search is faster than grid search but can be less efficient in finding the optimal solution.
Bayesian optimization is a more probabilistic approach to hyperparameter tuning where you use a prior distribution to guide the search for optimal values. Bayesian optimization can be more efficient than grid search or random search but can be more difficult to implement.
Benefits of hyperparameter tuning:
Improves the model's performance.
Reduces the need for manual hyperparameter tuning.
Enhances the robustness of the model
