Which constraints of a numerical problem cause ill-conditioning?
Nick Dewaele, Nick Vannieuwenhoven
Many numerical problems with input and output can be formulated as a system of equations where the goal is to solve for . The condition number measures the…

Three decompositions of symmetric tensors have similar condition numbers
Nick Dewaele, Paul Breiding, Nick Vannieuwenhoven
We relate the condition numbers of computing three decompositions of symmetric tensors: the canonical polyadic decomposition, the Waring decomposition, and a Tucker-compressed Wari…

The condition number of many tensor decompositions is invariant under Tucker compression
Nick Dewaele, Paul Breiding, Nick Vannieuwenhoven
We characterise the sensitivity of several additive tensor decompositions with respect to perturbations of the original tensor. These decompositions include canonical polyadic deco…
