Hyperparameter Tuning with Search Methods
Hyperparameter tuning is crucial for optimizing candidate machine learning models and scikit-learn makes this process easier with a variety of built-in search methods. The library provides the two most used methods, GridSearchCV()
and RandomizedSearchCV()
, in easy to implement APIs along with their counterpart methods that implement a successive halving approach to hyperparameter search.
Scikit-learn also allows a manual approach to setting hyperparameters if you desire to adjust default values for your own training purposes: the set_params()
and get_params()
methods. set_params()
allows users to adjust model hyperparameters programmatically, while get_params()
retrieves the current hyperparameter settings. This functionality ensures flexibility when experimenting with different model configurations and can be paired with the techniques mentioned earlier for efficient tuning.
