WebHNSW 的前身是 NSW (Navigable-Small-World-Graph) 。 NSW 通过设计出一个具有导航性的图来解决近邻图发散搜索的问题，但其搜索复杂度仍然过高，达到多重对数的级 … Navigable small world models are defined as any network with (poly/)logarithmic complexity using greedy routing. The efficiency of greedy routing breaks down for larger networks (1-10K+ vertices) when a graph is not navigable [7]. The routing (literally the route we take through the graph) consists of two phases. Ver más We can split ANN algorithms into three distinct categories; trees, hashes, and graphs. HNSW slots into the graph category. More specifically, it is a proximity graph, in which two vertices are linked based on their … Ver más During graph construction, vectors are iteratively inserted one-by-one.

WebA small-world network is a mathematical graph in which most nodes are not neighbors of one another, but the neighbors of any given node are likely to be neighbors of each other. Due to this, most neighboring nodes can be reached from every other node by a small number of hops or steps.
