Self-organizing maps clustering python

WebSomoclu is a highly efficient, parallel and distributed algorithm to train such maps, and its Python interface was recently updated. This enables fast training of self-organizing maps on multicore CPUs or a GPU from Python, albeit only on dense data, and the distributed computing capability is also not exposed. WebSep 2, 2024 · 1 Suppose that we train a self-organising map (SOM) with a given dataset. Would it make sense to cluster the neurons of the SOM instead of the original datapoints? This doubt came to me after reading this paper, in which the following is stated:
