Curse dimensionality

WebThe curse of dimensionality has different effects on distances between two points and distances between points and hyperplanes. An animation illustrating the effect on randomly sampled data points in 2D, as a 3rd dimension is added (with random coordinates). As the points expand along the 3rd dimension they spread out and their pairwise ... WebSep 19, 2024 · The curse of dimensionality says that, given a whole set of points, P, and a reference point, Q, if you compute the distance from Q to each of the points in P, the difference between the maximum distance and the minimum distance goes to 0. You need WAY more than 2 points to show that.
