Web“…However, the general K-means clustering algorithm needs to determine the number of clustering centers first, and the specific number is unknown in most cases. However, if the number of clustering centers is not set properly, the final clustering result will have a large error [21] - [23]. WebK-Means algorithm is one of the most used clustering algorithm for Knowledge Discovery in Data Mining. Seed based K-Means is the integration of a small set of labeled data (called seeds) to the K-Means algorithm to improve its performances and overcome its sensitivity to initial centers. These centers are, most of the time, generated at random or they are …
