1) How to pick hashing kernels? Would it be possible to use rate of collusion to select a set of hashing kernels? Or the hashing kernels need to be locality sensitive? 2) Is the hashing trick used in Vowpal Wabbit the same as Locality-sensitive hashing? 3) Is Locality-sensitive hashing a type of random projection?
