 Large-scale high-dimensional vector data has become ubiquitous in contemporary times. For instance, various forms of unstructured data, such as images, videos, texts, and speeches, are typically transformed into vectors using deep learning techniques. These vectors are subsequently employed in downstream analytical tasks. Nearest neighbor (NN) search in high-dimensional vector space constitutes a fundamental problem with a wide array of applications in information retrieval, recommendations, and retrieval-based large language models.

Recently, with the help of fast SIMD-based implementations, Product Quantization (PQ) and its variants can often efficiently and accurately estimate the distances between the vectors and have achieved great success in the in-memory ANN search. Despite their empirical success, we note that these methods do not have a theoretical error bound and are observed to fail disastrously on some real-world datasets. Motivated by this, we propose a new randomized quantization method named RaBitQ, which quantizes D-dimensional vectors into D-bit strings. RaBitQ guarantees a sharp theoretical error bound and provides good empirical accuracy at the same time. In addition, we introduce efficient implementations of RaBitQ, supporting to estimate the distances with bitwise operations or SIMD-based operations. Extensive experiments on real-world datasets confirm that (1) our method outperforms PQ and its variants in terms of accuracy-efficiency trade-off by a clear margin and (2) its empirical performance is well-aligned with our theoretical analysis.</p></div><footer class=post__footer><div class="post__tags tags clearfix"><svg class="tags__badge icon icon-tag" width="16" height="16" viewBox="0 0 32 32"><path d="M32 19c0 1-1 2-1 2L21 31s-1 1-2 1-2-1-2-1L2 16c-1-1-1.4-2-1.4-2S0 12.5.0 11V3C0 1.5.8.8.8.8S1.5.0 3 0h8c1.5.0 3 .6 3 .6S15 1 16 2l15 15s1 1 1 2zM7 10a3 3 0 100-6 3 3 0 000 6z"/></svg><ul class=tags__list><li class=tags__item><a class="tags__link btn" href=/tags/vector-db-algorithms/ rel=tag>Vector DB Algorithms</a></li><li class=tags__item><a class="tags__link btn" href=/tags/ann-search/ rel=tag>ANN Search</a></li></ul></div></footer></article></main><nav class="pager flex"><div class="pager__item pager__item--prev"><a class=pager__link href=/news/adsampling/ rel=prev><span class=pager__subtitle>«&#8201;Previous</span><p class=pager__title>ADSampling has been accepted by SIGMOD' 23</p></a></div><div class="pager__item pager__item--next"><a class=pager__link href=/news/irange/ rel=next><span class=pager__subtitle>Next&#8201;»</span><p class=pager__title>iRangeGraph has been received by SIGMOD' 25</p></a></div></nav></div></div><footer class=footer><div class="container footer__container flex"><div class=footer__copyright>&copy; 2024 Vector Database Group @ NTU.

Recently, with the help of fast SIMD-based implementations, Product Quantization (PQ) and its variants can often efficiently and accurately estimate the distances between the vectors and have achieved great success in the in-memory ANN search. Despite their empirical success, we note that these methods do not have a theoretical error bound and are observed to fail disastrously on some real-world datasets. Motivated by this, we propose a new randomized quantization method named RaBitQ, which quantizes D-dimensional vectors into D-bit strings. RaBitQ guarantees a sharp theoretical error bound and provides good empirical accuracy at the same time. In addition, we introduce efficient implementations of RaBitQ, supporting to estimate the distances with bitwise operations or SIMD-based operations. Extensive experiments on real-world datasets confirm that (1) our method outperforms PQ and its variants in terms of accuracy-efficiency trade-off by a clear margin and (2) its empirical performance is well-aligned with our theoretical analysis.</p></div><footer class=post__footer><div class="post__tags tags clearfix"><svg class="tags__badge icon icon-tag" width="16" height="16" viewBox="0 0 32 32"><path d="M32 19c0 1-1 2-1 2L21 31s-1 1-2 1-2-1-2-1L2 16c-1-1-1.4-2-1.4-2S0 12.5.0 11V3C0 1.5.8.8.8.8S1.5.0 3 0h8c1.5.0 3 .6 3 .6S15 1 16 2l15 15s1 1 1 2zM7 10a3 3 0 100-6 3 3 0 000 6z"/></svg><ul class=tags__list><li class=tags__item><a class="tags__link btn" href=/tags/vector-db-algorithms/ rel=tag>Vector DB Algorithms</a></li><li class=tags__item><a class="tags__link btn" href=/tags/ann-search/ rel=tag>ANN Search</a></li></ul></div></footer></article></main><nav class="pager flex"><div class="pager__item pager__item--prev"><a class=pager__link href=/news/adsampling/ rel=prev><span class=pager__subtitle>«&#8201;Previous</span><p class=pager__title>ADSampling has been accepted by SIGMOD' 23</p></a></div><div class="pager__item pager__item--next"><a class=pager__link href=/news/irange/ rel=next><span class=pager__subtitle>Next&#8201;»</span><p class=pager__title>iRangeGraph has been accepted by SIGMOD' 25</p></a></div></nav></div></div><footer class=footer><div class="container footer__container flex"><div class=footer__copyright>&copy; 2024 Vector Database Group @ NTU.
