Web17 Mar 2024 · Here, we consider the approximation of the non-negative data matrix X ( N × M) as the matrix product of U ( N × J) and V ( M × J ): X ≈ U V ′ s. t. U ≥ 0, V ≥ 0. This is known as non-negative matrix factorization (NMF (Lee and Seung 1999; CICHOCK 2009)) and multiplicative update (MU) rule often used to achieve this factorization. WebIn this work, we establish an asymptotic limit of almost-lossless compression of a random, finite alphabet tensor which admits a low-rank canonical polyadic decomposition.
