This is done by normalizing each dimension of a vector +relative to a centroid (mid-point pre-calculated against all vectors in the index) with the stored bit +representing whether the actual value is positive or negative of the centroid's value. A further "corrective factor" is computed +and stored to help compensate accuracy in the estimated distance.
