is pca linear is eigenvector obtained as a pca what are the eigenvectors of kernel pca is kernel pca a linear combination? if eigenvectors are orthogonal, what does this mean? what is the eigenvector in kernel pca how should eigenvectors of kernel be are eigenvectors obtained in kernel pca orthogonal? what is kernel pca matrix can pca be orthogonal are the eigenvectors obtained in kernel pca orthogonal? are eigenvectors obtained from kernel pca orthogonal what is eigenvector in kernel pca which pca problem has eigenvectors how to find the eigenvectors in the kernel which kernel is the same as pca? what are the eigenvectors? are eigenvectors obtained in kernel pca orthogonal why is the eigenvector obtained orthogonal pca kernel which is an orthogonal eigenvector? what is a linear combination of input and output
