Farthest neighbor

WebThe farthest neighbor method is a clustering technique that assigns each point in a dataset to the cluster with the farthest point from it. This method is used to create clusters of similar points. The farthest neighbor method is easy to understand and implement. It is also effective at creating clusters of similar points.
