K-means聚類演算法 - JerryLead - 博客園 K-means也是聚類演算法中最簡單的一種了,但是裡面包含的思想卻是不一般。最早我使用並實現這個演算法是在學習韓爺爺那本數據挖掘的書中,那本書比較註重應用。看了Andrew Ng的這個講義後才有些明白K-means後麵包含的EM思想。
K-means++ - Wikipedia, the free encyclopedia In data mining, k-means++[1][2] is an algorithm for choosing the initial values (or "seeds") for the k-means clustering algorithm. It was proposed in 2007 by David Arthur and Sergei Vassilvitskii, as an approximation algorithm for the NP-hard k-means prob
