WebMar 15, 2024 · The method is based on the distance between the object and its kNNs: given k and n, a point is an outlier if no more than n−1 other points in the data set have a higher value for D k than p. By calculating the distance from an object to its neighbors and sorting, the object with the largest value in the order is marked as an outlier. WebMar 31, 2024 · 2.2 Weighted KNN. Weighted KNN is an altered variant of KNN. The most straightforward strategy is to take the dominant part vote, yet this can be an issue if the closest neighbors fluctuate generally in their distances and the nearest neighbors indicate the class of test sample [].When k > 1, every neighbor has an associated weight with it …
