WebMay 11, 2015 · If you train your model for a certain point p for which the nearest 4 neighbors would be red, blue, blue, blue (ascending by distance to p). Then a 4-NN would classify your point to blue (3 times blue and 1 time red), but your 1-NN model classifies it to red, because red is the nearest point.
