mds-sammonmapping-isomap's Issues

Comparison between skelarn isomap and your own isomap

Dear bghojogh,

I have compared the results of your isomap implementation with respect the sklearn Isomap and the embedding space that gives is different. I have coded the sklearn isomap algorithm with the same Knn parameters and variables with respect your own isomap implementation.
Do you know which can be the cause?

Thank you in advance,
Best regards,
Marc
