What is hyperparameter tuning aimed at?

Hyperparameter tuning is a critical process in machine learning and artificial intelligence aimed at optimizing model performance by adjusting the settings that govern the learning process. Hyperparameters are the parameters that are set before the learning process begins, such as the learning rate, batch size, number of epochs, and the architecture of the model itself. By systematically searching for the optimal combination of these hyperparameters, one can enhance the model's ability to generalize well on unseen data, thus improving overall accuracy and performance.

In this context, the adjustments made during hyperparameter tuning can significantly influence how well the model learns from its training dataset. For example, a too high learning rate might prevent the model from converging, while a too low one could lead to longer training times without significant performance gains. By finely tuning these settings, practitioners can strike a balance that allows for effective training, yielding a model that performs well not just on the training data, but also on new, unseen examples.

The other options do not directly align with the objective of hyperparameter tuning; understanding the neural network structure is a separate concern focused on the architecture and design of the model itself, while selecting datasets pertains to data preparation rather than model optimization. Implementing regularization techniques is related to improving a model's
