Interesting, definitely need to think about debiasing. Seems like it won't really work straight out of the box since it'd destroy the 1 bit-ness of the vectors.
Though if only a few of the vectors are de-biased then you can still save a lot of space since all the other vectors are still represented using 2 numbers (while the de-biased vectors are represented using the full range of 32 bit numbers).
