번역 Hi guys, I have a sparse matrix and I need to find the 10 nearest neighbors between each row and the rest rows of the matrix. I used this command: [idx, D] =knnsearch(B,A,'distance','cosine','K',10); but the problem is that no matter which value I choose for K, ...
首先来说annoy,annoy全称“Approximate Nearest Neighbors Oh Yeah”,是一种适合实际应用的快速相似查找算法。Annoy 同样通过建立一个二叉树来使得每个点查找时间复杂度是O(log n),和kd树不同的是,annoy没有对k维特征进行切分。annoy的每一次空间划分,可以看作聚类数为2的KMeans过程。收敛后在产生的两个聚类中心连线...
