Improving uniformity by coordinate-wise power before projection
PVQ point density has characteristic nonuniformities - I have worked on improving it by adding some deformation, and just coordinate-wise power before applying projection works quite well, allows to reduce mean-squared quantization error by ~10% ( https://arxiv.org/pdf/1705.05285 ) - might be worth adding with image like attached: --Jarek Duda (talk) 13:42, 15 May 2021 (UTC)
