What could cause the TSNE to result in a dense centred ball and where to look for a solution.
I have 650K images with perplexity 50, angle 0.1, learning rate 1000.

Other attempts with similar sized batch of images did not exhibit this behaviour.

Any thoughts?

I have the same problem. Any solutions?

Does the same error happen also with other TSNE libraries? Could you share the code used for this experiment?
