WebIn addition, the traditional method of constructing similarity graphs is based on the pairwise distance, so it is extremely sensitive to the original data, and also lacks specific physical meaning from the perspective of probabilistic prediction. Final, the traditional metrics based on Euclidean distance is difficult to tackle non-Gaussian noise. WebJun 30, 2024 · In general, we view similarity as proximity with respect to some metric. A common way of converting a graph metric d into a similarity measure s is to let s (G, H) \coloneqq exp (− β ⋅ d (G, H)) for some constant β > 0.
