Null affinity matrices not being correctly normalized #2

Closed ejohnson643 closed 3 years ago

The "Warning: Illegal DKL values" flag comes up because affinity matrices are not being row-normalized correctly.

I fixed this by forcing t-SNE to ensure it has a locally-normalized affinity matrix (generating one if needed) before calculating the EES.
