How does ICA differ from Principal Component Analysis (PCA) in terms of data independence?
- ICA finds statistically independent components
- PCA finds orthogonal components
- ICA finds the most significant features
- PCA reduces dimensionality
Independent Component Analysis (ICA) seeks statistically independent components, meaning they are as unrelated as possible, while PCA seeks orthogonal components that explain the most variance but are not necessarily independent. ICA focuses on data independence, making it suitable for source separation tasks.
