然而,HNSW-retrieval在实际应用中不足以处理现实世界中推荐系统的大规模检索任务,因为它存在以下缺陷:1)HNSW-retrieval中的SEARCH-LAYER子程序采用while循环探索图,这使得在线推理的计算量和延迟难以控制;2)简单的贪心搜索遍历更容易陷入局部最优,特别是在我们的情况下,s_u(e_v)通常是非凸的。因此,我们根据算法2对...
Approximate Nearest Neighbor Search(ANNS)目录Approximate Nearest Neighbor Search(ANNS) 树方法 kd-tree在一个给定的空间(或集合)中找到距离兴趣(或目标)对象最近的邻居,这个问题在多种领域都是非常基本而重要的, 如生物、医学、地理、机器人、互联网等等只要涉及数据检索、机器学习、大规模数据处理等基本都会需要。

(1):ε-approximate nearest neighbor searchis a special case of thenearest neighbor search problem. The solution to the ε-approximate nearest neighbor search is a point or multiple points within distance (1+ε) R from a query point, where R is the distance between the query ...
-MNG;并且在其上使用beam search提升精度,且提供了一个优化方案能做一些剪枝。 3 PRELIMINARIES 3.2 Proximity graph MRNG是月牙形裁边,在月牙内的点可以驱逐月牙边的点,即120度内不能有更短的边。 MRNG很好的性质是只要query在数据库内,从任意点出发肯定可以找到NN。
