Latest update (11-10 18:20): Meta FAIR releases e-means, a k-means variant that reaches Lloyd's loss in fewer epochs

Overview: Meta FAIR researchers release e-means, a drop-in replacement for Lloyd's k-means clustering algorithm. According to MarkTechPost, e-means reaches the loss that Lloyd's k-means reaches in 25 epochs in 1.4 to 2.6 epochs. It uses exponential moving average updates and ships in FAISS 1.16.0 under faiss.contrib.e_means.

The authors report speedups of 10-45x on GPU and 8-15x on CPU. These figures are self-reported and come from the authors, not from independent testing.
