SOS Performance

[MikeB2019x]

I noticed a comment in test_sos.py:

# TODO: check performance is turned off due to poor performance.

I am curious what this means. The reason is I want to modify the compare_all_models.py to include the SOS model. So just trying to understand the implementation and any challenges it has.

Update: Actually, SOS doesn't seem to be working. I did some varying of perplexity and epsilon and was unable to achieve a successful performance. In all cases all points are colored as inliers maybe because some of the outliers are scored as inliers (and vice versa).
