Why might PCA be considered a method of feature selection?
- It can handle correlated features
- It can improve model performance
- It can reduce the dimensionality of the data
- It transforms the data into a new space
Principal Component Analysis (PCA) can be considered a method of feature selection because it reduces the dimensionality of the data by transforming the original features into a new set of uncorrelated features. These new features, called principal components, are linear combinations of the original features and are selected to capture the most variance in the data.
