ImageNet-1k's covariance matrix's eigenvalues (eigenvalues_ipca.npy), the ratio of total variance explained by each of ImageNet-1k's principal component (eigenvalues_ratio_ipca.npy), ImageNet-1k's principal components (pc_matrix_ipca.npy) computed using the normalized training dataset. For computational reasons, only 10% of the training dataset was used for PCA and only the top 20k principal components were computed.
These items were used in [1]. The ImageNet-1k dataset was presented in [2].
