Oracle solver not converging on Scheetz2006 #44
Comments
I have tried to look a bit. My guess is that 1e-4 as tol is not enough to identify the true clusters and giving it as w_star does not work. But I have tried fixing it and haven't succeeded yet... |
As @mathurinm notes in #48, there is actually no problem. The oracle just doesn't have the right clusters in the example above. |
Yeah, I tried a lower tolerance too (I think 1e-10) but it made no difference. I noticed that the Scheetz2006 is very unstable with regards to the clusters, so this is probably it.
We can keep this open but I think it's not a real problem since we are not going to use the oracle solver for most of the experiments (right?). We just need it to show for a few examples how our method compares with the "best-you-can-do".

Now I am seeing weird issues with Scheetz2006 and the oracle solver.
Check out the following example.
