i could be mistaken but from my read, the 'rotation' aspect is nothing new and not dissimilar from normal spin quant, where the importance matrix is rotated during calibration such that the local minima/maxima are more evenly smoothed and excessive/redundant quantization of parameters is avoided.

as for the J-L transformation is way above my head so i'm almost certainly mistaken but it seems to be some clever way to use a bit as a sort of pointer in order to reuse existing chunks of parameter weight data like in a jpeg or zip compression algorithm.
