问题 I would like to bin vectors in n-dimensional space. This can be done by pixelating the surface of an n-dimensional hypersphere.

My space consists of only positive integers. 回答1: Do you need your bins to be perfectly regular? If not, just throw points out at random, and measure distance to the nearest neighbor. You could clean this up slightly by throwing away points that are too close, or

Can't remove Whitespace at the bottom of my document
