eigenvalues. Imagine you have mapped out a data set with multiple features, resulting in a multi-dimensional scatterplot. Eigenvectors provide the "direction" within the scatterplot. Eigenvalues denote the importance of this directional data. A high eigenvalue means the associated eigenvector is more...
resulting in a multi-dimensional scatterplot. Eigenvectors provide the direction of variance in the scatterplot. Eigenvalues are the coefficients of the eigenvectors; these denote the importance of this directional data. Therefore, a high eigenvalue means that the corresponding eigenvector is more criti...
