| Apr 4, 2011 at 23:16 | comment | added | Aaron Meyerowitz | Lindenstrauss-Johnson says that there are subspaces which make the distance between the projections "close" to the distance between the original points. Here the desire is to have the projections be small so ideally one might want the projection to shrink distances as far as possible. | |
