Web21 mei 2014 · If you increase k, the areas predicting each class will be more "smoothed", since it's the majority of the k-nearest neighbours which decide the class of any point. Thus the areas will be of lesser number, larger sizes and probably simpler shapes, like the political maps of country borders in the same areas of the world. Thus "less complexity". Web10 okt. 2024 · KNN is a lazy algorithm that predicts the class by calculating the nearest neighbor distance. If k=1, it will be that point itself and hence it will always give 100% …
