Why Use Random Forest for Feature Selection?

Random Forest is particularly suited for feature selection for several reasons:

• Intrinsic Feature Ranking: Random Forest provides a built-in method to evaluate the importance of features.
• Handles High Dimensionality: Effective even when the number of features is much larger than the number of samples.
• Non-Linearity: Can capture complex interactions between features without requiring explicit specification of interactions.

Feature selection is a crucial step in building machine learning models. It involves selecting the most important features from your dataset that contribute to the predictive power of the model. Random Forest, an ensemble learning method, is widely used for feature selection due to its inherent ability to rank features based on their importance.
