# How to find optimal parameters for CatBoost using GridSearchCV for Regression in Python

To find the optimal parameters for CatBoost using GridSearchCV for Regression in Python, you can follow these steps:

Define the CatBoost model and specify the range of parameter values you want to test. These can include parameters such as depth, learning rate, and number of trees.

Use the GridSearchCV function from scikit-learn library to search for the best combination of parameters. This function will take the CatBoost model, the parameter grid, and some additional settings such as the number of cross-validation folds to use.

Fit the model to the training data using the GridSearchCV function.

After the grid search is finished, the best combination of parameters can be accessed by calling the “best_params_” attribute of the GridSearchCV object.

It’s important to note that the process of finding optimal parameters for a model can be time-consuming and computationally expensive, especially when the number of parameters or the range of values for each parameter is large. But GridSearchCV will help you to get the best combination of parameters which will improve your model’s performance.

In this Machine Learning Recipe, you will learn: How to find optimal parameters for CatBoost using GridSearchCV for Regression in Python.
