kmeans clustering : 维基百科:http://en.wikipedia.org/wiki/Kmeans kmedoids clustering : 维基百科:http://en.wikipedia.org/wiki/K-medoids 虽然上面三种算法都很好理解,但是这都是基础算法,要想深入,还有很多很多相关问题需要解决,比如k如何设置;随机选取初始点的问题等等,而且如何选取好用的聚类算法也值得商榷。
K-Means Clustering is one of the popular clustering algorithm. The goal of this algorithm is to find groups(clusters) in the given data. In this post we will implement K-Means algorithm using Python from scratch.
% kMeans algorithm. In this part, you will run the K-Means algorithm on % the example dataset we have provided. % fprintf('\nRunning K-Means clustering on example dataset.\n\n'); % Load an example dataset load('ex7data2.mat'); % Settings for running K-Means K = 3; max_iters ...
