Value-Decomposition Networks For Cooperative Multi-Agent Learning SVD is a factorisation of a matrix, where given an matrix X, SVD factorises X into U, an unitary matrix, , an rectangular diagonal matrix with non-negative real numbers on the diagonal, and V, an unitary matrix. This class of learning problems is difficult because of the often large combined action and observation spaces. Reverse engineering gene networks using singular value decomposition Generalized Singular Value Decomposition (GSVD) can be used to identify sub-network structures and for comparative analysis of genomic datasets across two conditions [11], [23]. 2365-2369, 2013.
