Error when load similarity matrix

[renxwise]

The speed of FIt-SNE is amazing. Can FIt-SNE accept precomputed similarity matrix? I used the Matlab wrapper and inputted a precomputed similarity matrix with the "load" option, but errors were reported by showing that cannot find the file.

Wow, I'm so sorry that I missed this! I got behind because of the holidays.

The load option only loads a matrix in the format that is saved by the software iteslf. It is designed so that you don't have to recompute the affinity matrix every time you run it, if you run it multiple times on the same data. It's not really designed for users to give their own matrix.

But this would be a great feature to implement. Note that it is already implemented in a branch of an fork from a while ago, but I did not have a chance to incorporate it into the main repository...and there have been some updates to FIt-SNE since then. See here for an example of how to run it on that older version. Note that the code will still symmetrize and normalize the user-specified P to be a Markov matrix.

@renxwise I think your issue is solved here:
