【摘要】The k-means algorithm is a popular data clustering technique due to its speed and simplicity. However, it is susceptible to issues such as sensitivity to the chosen seeds, and inaccurate clusters due to poor initial seeds, particularly in complex datasets or datasets with non-spherical ...
We show that the K-Means algorithm actually minimizes the quantization error using the very fast Newton algorithm. 1 INTRODUCTION K-Means is a popular clustering algorithm used in many applications, including the initialization of more computationally expensive algorithms (Gaussian mixtures, Radial Basis...
The K-Means (KM) algorithm is a popular algorithm which attempts to find a K- clustering which minimizes MSE. The K-Means algorithm is a centerbased clustering algorithm. The dependency of the K-Means performance on the initialization of the centers is a major problem; a similiar issue ...
Training Algorithm Details K-means is a popular clustering algorithm. With K-means, the data is clustered into a specified number of clusters in order to minimize the within-cluster sum of squared distances. This implementation follows the Yinyang K-means method. For choosing the initial cluster...

Classical K-means is a popular clustering algorithm,but it's sensitive to initial mean points,and is mostly influenced by noisy and abnormal data.So the paper provides a two times K-means algorithm based on grid.Firstly,the algorithm divides the space to many equal grids,and then gets dense...
