Graphical explanation of the effective distance. a A graph with three nodes with equal edge weight quantified by gray arrows, which can represent the Euclidean distance. b The probability \(P\left( {m|n} \right)\) of the sample \(n\) belonging to \(m\)’s class is calculated in the effective distance. The magnitude of these levels is indicated by the line width. For example, the sample B has a smaller probability belonging to A’s class than vice versa in the global view
