European astronomers have investigated a galaxy cluster designated CIZA J2242.8+5301, dubbed the Sausage cluster. The ...

Abstract: The traditional k-means algorithm has randomness in the selection of the initial clustering center, which is easy to fall into local optimum. In order to select the appropriate initial ...

A silhouette-guided instance-weighted k-means algorithm that integrates silhouette scores into the clustering process to improve clustering quality.

Hierarchical clustering, a widely used clustering technique, can offer a richer representation by suggesting the potential group structures. However, parallelization of such an algorithm is ...
