K-means clustering can be used to classify observations into k groups, based on their similarity. Each group is represented by the mean value of points in the group, known as the cluster centroid. K-means algorithm requires users to specify the number of cluster to generate. The R function...
Exploring Assumptions of K-means Clustering using R K-Means Clustering is a well known technique based on unsupervised learning. As the name mentions, it forms ‘K’ clusters over the data using mean of the data. Unsupervised algorithms are a class of algorithms one should tread on carefully....

that the first initial guesses are random and compute the distances until the algorithm reaches a homogeneity within groups. That is, k-mean is very sensitive to the first choice, and unless the number of observations and groups are small, it is almost impossible to get the same clustering. ...
k均值聚类算法(k-meansclustering algorithm)是一种迭代求解的聚类分析算法,其步骤是,预将数据分为K组,则随机选取K个对象作为初始的聚类中心,然后计算每个对象与各个种子聚类中心之间的距离,把每个对象分配给距离它最近的聚类中心。 聚类数为2,将数据聚成2个类别 ...
For example, specify the cosine distance, the number of times to repeat the clustering using new initial values, or to use parallel computing. example [idx,C] = kmeans(___) returns the k cluster centroid locations in the k-by-p matrix C. example [idx,C,sumd] = kmeans(___) return...
