Sklearn minibatchkmeans

Webb22 apr. 2024 · With 200k instances you cannot use spectral clustering not affiniy propagation, because these need O (n²) memory. So either you choose other algorithms or subsample your data. Obviously there is also no use in doing both kmeans and minibatch kmeans (which is an approximation to kmeans). Use only one. To efficiently work with …
