The curse of dimensionality is the result of correlatives of the fact that:
at higher dimensions, most random data points become equidistant from each other &mdash; you can prove this to yourself pythagoras and some math of expectation
random vectors are almost orthogonal unit sphere takes almost no volume in unit square (?)
