Principal Component Analysis
Principal Component Analysis (PCA) is a powerful statistical technique used for dimensionality reduction in data analysis. It transforms a dataset into a set of orthogonal components, capturing the most significant variance in the data while reducing its complexity. By projecting high-dimensional data onto a lower-dimensional space, PCA simplifies the dataset, making it easier to visualize and interpret. This method is particularly useful in identifying patterns and relationships within the data, facilitating tasks such as clustering and feature extraction. However, PCA may also lead to challenges in interpretability, as the principal components are linear combinations of the original features.
