Web2 nov. 2024 · In true machine learning fashion, we'll ideally ask the machine to perform this exploration and select the optimal model architecture automatically. Parameters which define the model architecture are referred to as hyperparameters and thus this process of searching for the ideal model architecture is referred to as hyperparameter tuning.

Unlike parameters, finding hyperparameters in training data is unattainable. As such, to find the right hyperparameters, we create a model for each combination of hyperparameters. Grid search is thus considered a very traditional …
Webhyperparameter can become computationally expensive [5]. Therefore, the need for an automated and structured way of searching is increasing, and hyperparameter space, in general, is substantial. Numerous works have been done in optimizing the hyperparameters [3], [6]–[8]. Other optimization methods that
