Answer: To explore every possible combination of hyperparameters within a predefined set
The primary objective of grid search in hyperparameter tuning is to methodically examine a specified grid of hyperparameter combinations for a machine learning algorithm. It evaluates each possible combination within the grid to discover the hyperparameters that optimize the model's performance. This technique is widely used for hyperparameter tuning, enabling an efficient search across various hyperparameter values. By assessing the model's effectiveness for every combination in the grid, grid search aids in pinpointing the best hyperparameters that enhance model performance on a validation set or via cross-validation.
