See cuvs rabitq. The RaBitQ Library provides efficient and lightweight implementations of the RaBitQ quantization algorithm (1-bit version and multi-bit version) and its applications in high-dimensional vector search. It also provides a GPU implementation. The core algorithm RaBitQ is based on the research from VectorDB group at Nanyang Technological University, Singapore. The library is developped by Yutong Gou, Jianyang Gao, Yuexuan Xu, Jifan Shi and Zhonghao Yang. The library provides the following key features: RaBitQ - a vector quantization algorithm as a drop-in replacement of binary and scalar quantization, offering an optimal theoretical error bound RaBitQ for Vector Search - a reference implementation of RaBitQ's combination with popular vector search indexes RaBitQLib supports estimating similarity metrics including Euclidean distance, inner product and cosine similarity. RaBitQ RaBitQ is a vector quantization algorithm as a drop-in replacement of binary and scalar quantization. The key advantages of RaBitQ include - High Accuracy with Tiny Space - RaBitQ achieves the state-of-the-art accuracy under diverse bit-width for the estimation of similarity metrics. It produces promising accuracy with even 1-bit per dimension . - Fast Distance Estimation - RaBitQ supports to estimate the similarity metrics with high efficiency based on bitwise operation","default_branch":null,"files":null,"tree":[],"storefront":"/r/VectorDB-NTU","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/VectorDB-NTU/RaBitQ-Library/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
