Clustering is a fundamental experimental procedure in data analysis. It is used in virtually all natural and social sciences and has played a central role in biology, astronomy, psychology, medicine, and chemistry. Despite the importance and ubiquity of clustering, existing algorithms suffer from a variety of drawbacks and no universal solution has emerged. We present a clustering algorithm that reliably achieves high accuracy across domains, handles high data dimensionality, and scales to large datasets. The algorithm optimizes a smooth global objective, using efficient numerical methods. Experiments demonstrate that our method outperforms state-of-the-art clustering algorithms by significant factors in multiple domains.
