This article describes how the most widely used clustering, k-means, is prone to fall into a local optimum. Notably …, traditional clustering approaches are directly performed on private data and fail to cope with malicious attacks in massive data … as leaks through system resources and clustering outputs. To address these issues, the authors propose an efficient …
