Models and Benchmarks for Representation Learning of Partially Observed Subgraphs

1 code implementation1 Sep 2022 Dongkwan Kim, Jiho Jin, Jaimeen Ahn, Alice Oh

Subgraphs are rich substructures in graphs, and their nodes and edges can be partially observed in real-world tasks.

Subgraphs are important substructures of graphs, but learning their representations has not been studied well.

$q$-Kreweras numbers for coincidental Coxeter groups attached to limit symbols

no code implementations15 Dec 2020 Dongkwan Kim

For a coincidental Coxeter group, i. e. of type $A_{n-1}, BC_n, H_3,$ or $I_2(m)$, we define the corresponding $q$-Kreweras numbers attached to limit symbols in the sense of Shoji.
