Non-Clashing Teaching Maps for Balls in Graphs

no code implementations6 Sep 2023 Jérémie Chalopin, Victor Chepoi, Fionn Mc Inerney, Sébastien Ratel

For Gromov-hyperbolic graphs, we design an approximate NCTM$^+$ for $\mathcal{B}(G)$ of size 2.

Sample compression schemes for balls in graphs

no code implementations27 Jun 2022 Jérémie Chalopin, Victor Chepoi, Fionn Mc Inerney, Sébastien Ratel, Yann Vaxès

The compressor maps any realizable sample $X$ to a subsample $X'$ of size at most $k$.

Labeled sample compression schemes for complexes of oriented matroids

no code implementations28 Oct 2021 Victor Chepoi, Kolja Knauer, Manon Philibert

We show that the topes of a complex of oriented matroids (abbreviated COM) of VC-dimension $d$ admit a proper labeled sample compression scheme of size $d$.
