Balanced kmeans with cuda support in Pytorch.
Balanced K-Means clustering in PyTorch
Balanced K-Means clustering in Pytorch with strong GPU acceleration.
Disclaimer: This project is heavily inspired by the project kmeans_pytorch. Each part of the original implementation is combined with the appropriate attribution.
As easy as:
pip install balanced_kmeans
First things first: Classical kmeans algorithm as easy as
from balanced_kmeans import kmeans # experiment constants N = 10000 batch_size = 10 num_clusters = 100 device = 'cuda' cluster_size = N // num_clusters X = torch.rand(batch_size, N, dim, device=device) choices, centers = kmeans(X, num_clusters=num_clusters)
Now, if you want balanced kmeans you can run:
from balanced_kmeans import kmeans_equal N = 10000 batch_size = 10 num_clusters = 100 device = 'cuda' cluster_size = N // num_clusters X = torch.rand(batch_size, N, dim, device=device) choices, centers = kmeans_equal(X, num_clusters=num_clusters)
By default, forge initialization scheme is used for initial cluster centers.
However, you may change the initial cluster centers by providing the keyword
initial_state to either
This is a pet project, so feel free to contribute if you want to add any extra feature. For any bugs, please open a detailed issue.
This implementation extends the package
kmeans_pytorch which contains the
implementation of the original Lloyd's K-means algorithm in Pytorch. You can check (and star!)
the original package here.
