Partitioning a large set of objects into vision than any existing radio telescopes, answering homogeneous clusters is a fundamental operation in data fundamental questions about the Universe. However, with a mining and big data. The k-means algorithm is best suited for implementing this operation ...

Modified K-means clustering algorithm is a direction to solve this problem. Guha et al. [16] proposed the CURE method, which makes use of multiple representative points to obtain the “natural” clusters shape information. The problem of outliers and noise in the data can also reduce ...
The clustering algorithm is becoming more and more important in the field of data mining, but the traditional clustering algorithm does not take the clustering efficiency and clustering effect into consideration. In this paper, the algorithm based on K-Means and clustering by fast search and find ...
SparsifiedKMeans KMeans for big data using preconditioning and sparsification, Matlab implementation. Uses theKMeans clustering algorithm(also known asLloyd's Algorithmor "K Means" or "K-Means") but sparsifies the data in a special manner to achieve significant (and tunable) savings in computatio...
