knn clustering
Clustering and kNN. ,In this work we use an efficient search based on a clustering strategy. The main assumption is that the k-nearest neighbors of a given instance lie in the same cluster. Thus, the kNN search can be efficiently performed in two steps: (i) reaching the neare

Short answer: yes. You could do more than theorize runtime. You could terminate k-means based on runtime instead of the number of iterations. So you can predict how long k-means would run down to the... https://stats.stackexchange.co Clustering and kNN - YouTube

演算法(K-Nearest Neighbor Clustering). 每一點各自找到距離最近的K個點作為鄰居,採多數決歸類到群集。如果距離超過了自訂臨界值,找不足K個鄰居,就替該點創造一個新的群集。 優點是不用煩惱群集數量,缺點是群集鬆散。 演算法(Jarvis-Patrick Clustering). 每一點各自找到距離最近的K個點做為鄰居。當a和b彼此都是鄰居, ... http://www.csie.ntnu.edu.tw |
