Query: Invariants of multidimensional time series based on their
  iterated-integral signature   We introduce a novel class of features for multidimensional time series, that
are invariant with respect to transformations of the ambient space. The general
linear group, the group of rotations and the group of permutations of the axes
are considered. The starting point for their construction is Chen's
iterated-integral signature.
