e-means beats k-means with 10x fewer epochs, now shipped in Meta's FAISS

swannbessa introduced e-means, a clustering algorithm that beats k-means with roughly 10x fewer epochs and order-of-magnitude wall-clock speedups. It requires no hyperparameter tuning beyond k, stays robust across scales and datasets, and has been released in Meta's FAISS library. A 10-post technical thread invites skeptics to try it directly.
