Continuous k-nearest neighbors

WebDec 8, 2024 · To facilitate efficient retrieval of Voronoi cells and processing of continuous nearest neighbor (CONN) queries, we propose a new grid-based index, called Voronoi … WebTo perform k k -nearest neighbors for classification, we will use the knn () function from the class package. Unlike many of our previous methods, such as logistic regression, knn () requires that all predictors be numeric, so we coerce student to be a 0 and 1 dummy variable instead of a factor. (We can, and should, leave the response as a factor.)
