Dowker complex based machine learning (DCML) models for protein-ligand binding affinity prediction
Fig 4
A bipartie graph and its associated Dowker complex.
It can be seen that there are two disjoint components in DC, one is from the black points and the other is from the green points. Note that a triangle (2-simplex) is formed among the black point set in DC, as the corresponding three black vertices have a common neighbor blue vertex in the bipartite graph.
