And the fast nearest neighbors search improves the speed of DPC. In the experiment, KS-FDPC is used to compare with eight improved DPC algorithms on eight synthetic data and eight UCI data. The results indicate that the overall clustering performance of KS-FDPC is superior to other algorithms. Moreover, KS-FDPC runs faster than other algorithms.The first proposal to select a representative subset of prototypes for a further nearest neighbour classification corresponds to Wilson editing algorithm [5], in which a k-NN classifier is used to retain in the TS only good samples (that is, training samples that are correctly classified by the k-NN rule).

Project StructureWeighted K-NN. Weighted kNN is a modified version of k nearest neighbors. One of the many issues that affect the performance of the kNN algorithm is the choice of the hyperparameter k. If k is too small, the algorithm would be more sensitive to outliers. If k is too large, then the neighborhood may include too many points from other classes.Repetitive Nearest Neighbour Algorithm Pick a vertex and apply the Nearest Neighbour Algorithmwith the vertex you picked as the starting vertex.

This edits out noisy instances

I'm trying to develop 2 different algorithms for Travelling Salesman Algorithm (TSP) which are Nearest Neighbor and Greedy. I can't figure out the differences between them while thinking about cities.
