# e-means: outperforming k-means (in one-tenth the epochs) > Source: > Published: 2026-11-10 21:30:08+00:00 Lloyd's k-means algorithm is a long-running standard for clustering, with applications in data analysis, retrieval, quantization and data curation. In this paper, we introduce an exponential moving average optimization procedure for k-means with mini-batch updates, powered by modern deep learning ma
