Cluster analysis is a widely used unsupervised learning technique designed to classify samples on the basis of their similarity 1. This technique presents a challenging problem in data mining and ...

The nearest neighbor problem asks where a new point fits into an existing data set. A few researchers set out to prove that there was no universal way to solve it. Instead, they found such a way. If ...

DPC (density peaks clustering) algorithm has garnered widespread attention due to its novelty and superior performance. However, it is sensitive to the arbitrary cutoff distance, and its very ...
