Quantitative Bounds for Sorting-Based Permutation-Invariant Embeddings
Nadav Dym, Matthias Wellershoff, Efstratios Tsoukanis +2
We study permutation-invariant embeddings of -dimensional point sets, which are defined by sorting independent one-dimensional projections of the input. Such embeddings aris…

Stability of sorting based embeddings
Radu Balan, Efstratios Tsoukanis, Matthias Wellershoff
Consider a group of order acting unitarily on a real inner product space . We show that the sorting based embedding obtained by applying a general linear map $α: \mathb…
