선형대수 많이 까먹어서.. 기억을 되짚어보기 위해 올립니다. reference : Deep learning (Ian Goodfellow, Yoshua Bengio, Aaron Courville)EigendecompositionEigendecomposition means that we decompose a matrix into a set of eigenvectors and eigenvalues. An eigen vector of a square matrix A is a nonzero vector $v$ such that multipication by A alters only the scale of $v$ $Av = \lambda v$ the scalar $\lambda$ is known as eigenva..
