pytorch implementation of algorithm described in Visualizing Data using t-SNE. This code support cuda accelerating.

Just download the repository, and the unzip mnist2500_X.zip or put feature file and labels file with code

1. run without cuda support

python tsne_torch.py --xfile mnist2500_X.txt --yfile mnist2500_labels.txt --cuda 0

2.run with cuda support

python tsne_torch.py --xfile mnist2500_X.txt --yfile mnist2500_labels.txt --cuda 1

Note: The input data should be normalized to the range [0.0, 1.0], otherwise you may get the 'nan' result.

This is our result compare to result of python implementation.

• pytorch result
• use time 352s on 2080Ti GPU

• python result
• use time 634s on CPU

This code highly inspired by
