Shared nearest neighbor python
WebbSNN （shared nearest neighbor） SNN是一种基于共享最近邻的聚类算法，它通过使用数据点间共享最近邻的个数作为相似度来处理密度不同的聚类问题，从而可以在含有噪音并 … WebbWe introduce a revised method by conditioning the high-dimensional similarities instead of the low-dimensional similarities and storing within- and across-label nearest neighbors separately. This also enables the use of recently proposed speedups for t …
