What are the best practices for using Scikit-Learn?

Some best practices include: 1) Properly splitting your data into training and testing sets, 2) Standardizing your features, 3) Using pipelines for preprocessing and modeling, and 4) Tuning hyperparameters with cross-validation.

Can you explain why data splitting is important?

Data splitting is crucial because it helps to evaluate the model's performance on unseen data, preventing overfitting and ensuring that the model generalizes well.

What is the role of pipelines in Scikit-Learn?

Pipelines streamline the workflow by chaining together preprocessing steps and the model itself, making the code cleaner and reducing the risk of data leakage.

How do I perform hyperparameter tuning?

You can use techniques like GridSearchCV or RandomizedSearchCV to systematically explore different hyperparameter combinations and find the best settings for your model.

Any tips for feature selection?

Yes! You can use techniques like Recursive Feature Elimination (RFE), feature importance from tree-based models, or regularization methods to select the most relevant features.
