Primary eigenvector
WebThe matrix is decomposed by Eigenvalue Decomposition (EVD) and used to construct the eigenvector σ, and the second feature extraction and data compression are completed. The mean value d 1 , the root mean square value d 2 and standard deviation value d 3 of σ are extracted, the third feature extraction and data compression are completed. WebIn linear algebra, the eigenvectors of a square matrix are non-zero vectors which when multiplied by the square matrix would result in just the scalar multiple of the vectors. i.e., a …
