Find a version of the symmetric least-squares error that forms a metric on the set of delta signatures with n terms. This should ideally itself be a solution to a least-squares optimization problem. | Find a version of the symmetric least-squares error that forms a metric on the set of delta signatures with n terms.

Project the set of delta signatures with ''n'' terms (as directions of lines in <math>\mathbb{R}^n</math> onto the sphere <math>S^{n-1}</math> and measure the distance on the sphere. This results in the ''round metric''{{idiosyncratic}}. | |||
