Comment on Lecture 6: Dimensionality Reduction by the Johnson-Lindenstrauss Lemma by hypergeometric

Wed, 18 Jan 2017 21:59:07 +0000http://nickhar.wordpress.com/?p=115#comment-666Great and interesting post! With the rush to use MinHash, based upon Johnson-Lindenstrauss, for doing things like clustering character tokens, it’s nice to see its potential for doing dimension reduction of continuous measures and of counts, which is what I am interested in doing.

Can you fix the presentation of Alon’s Theorem 3 above?

Sat, 07 Mar 2015 03:50:01 +0000http://nickhar.wordpress.com/?p=134#comment-367What do you mean by a polynomial p defined over a finite field F being identically 0? Is it that p is the zero of the polynomial ring F[x1, …, xn] or that p vanishes on all of F^n?
