Subject Hash-coded Vectorization and bogus information
Date Sun, 12 Feb 2012 05:37:24 GMT
Does hash-coded vectorization add bogus information compared to sparse
term vectors? A more concrete question: would a random projection on
the sparse vector give a "better quality" dense vector? (This is in
the context of SGD classification, which "likes" dense vectors.)
