Pick the correct statements on PCA. C] The variance captured by the first principal component is Jiflff l) where N is the number of data points. [3 PCA based on correlation matrix is unaffected by the standard scaling of the data. D Covariance based PCA requires a lesser number of PCs to capture the same variance in comparison to correlation based PCA. [:J PCA is not affected by the presence of outliers. C] While using PICA for eigenfaces, the results remains unaffected by the variations in the ambient light for different images
