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…

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…
