Tensor decomposition and Prony's method
A higher-order tensor can be seen as a generalization of a matrix, a multi-dimensional array. The problem of decomposing such a tensor into a sum of rank-1 tensors then generalizes the Singular Value Decomposition of a matrix, an important tool in numerical linear algebra. After introducing the tensor decomposition problem, we relate it to Prony's method, a tool for recovering point measures from moments with applications in signal processing.
