WebJul 23, 2024 · Our algorithm hinges on the idea of compressing each convolutional (or fully-connected) layer by slicing its channels into multiple groups and decomposing each group via low-rank decomposition. At the core of our algorithm is the derivation of layer-wise error bounds from the Eckart Young Mirsky theorem. WebJul 31, 2006 · Abstract The singular value decomposition (SVD) has been extensively used in engineering and statistical applications. This method was originally discovered by Eckart and Young in [ Psychometrika, 1 (1936), pp. 211--218], where they considered the problem of low-rank approximation to a matrix.
