PyTorch implementation of the k-means algorithm
This code works for a dataset, as soon as it fits on the GPU. Tested for Python3 and PyTorch 1.0.0.
For simplicity, the clustering procedure stops when the clustering stops updating. In practice, this might be too strict and should be relaxed.
There is a magic constant (search for
chunk_size) which should ideally be determined automatically based on the amount of free memory on the GPU.
