To achieve X32 compute efficiency and retain ∼96% of retrieval performance, the binary quantization is powered by the normalization of embedding values (either 0 or 1), the calculation of Hamming Distance with only 2 CPU runtimes, and the application of ReRank step of [Yamada et al (2021)](https://arxiv.org/abs/2106.00882).*")
