Tensor-to-Tensor Models with Fast Iterated Sum Features
Joscha Diehl, Rasheed Ibraheem, Leonard Schmitz +1
Data in the form of images or higher-order tensors is ubiquitous in modern deep learning applications. Owing to their inherent high dimensionality, the need for subquadratic layers…

The barycenter in free nilpotent Lie groups and its application to iterated-integrals signatures
Marianne Clausel, Joscha Diehl, Raphael Mignot +3
We establish the well-definedness of the barycenter (in the sense of Buser and Karcher) for every integrable measure on the free nilpotent Lie group of step (over $\mathbb{R}^d…

Two-parameter sums signatures and corresponding quasisymmetric functions
Joscha Diehl, Leonard Schmitz
Quasisymmetric functions have recently been used in time series analysis as polynomial features that are invariant under, so-called, dynamic time warping. We extend this notion to…
