| Mar 26, 2021 at 19:49 | comment | added | maths soso | @Sören what do you mean by missing values? np.dot(x.T, x) is a covariance matrix, I'd love to show the data, but I don't know how to show you a 60000x20 matrix | |

| Mar 26, 2021 at 19:38 | comment | added | maths soso | @NikosM. what do you mean? this is an array of eigenvalues. | |
