Apr 10, 2021 · k-nearest neighbor (kNN) is a widely used learning algorithm for supervised learning tasks. In practice, the main challenge when using kNN is its high sensitivity to its hyperparameter setting, including the number of nearest neighbors k, the distance function, and the weighting function. To improve the robustness to hyperparameters, this study presents a novel kNN learning method based on a ...

I also know that deg(v) is supposed to equal the number of edges that are connected on v, and if an edge is a loop, its counted twice.I can see why you would think that. For n=5 (say a,b,c,d,e) there are in fact n! unique permutations of those letters.
