comment Assumptions aren't working in this sum
@MichaelE2 Thanks, do know you why the Assumptions need to be put in two places? because the inner assumption seems to do nothing Assuming[\[Alpha] > 0 && \[Beta] > 0, FullSimplify@ ComplexExpand[ FullSimplify@Sum[1/(\[Alpha] n^4 + \[Beta]), {n, 1, \[Infinity]}], TargetFunctions -> {Re, Im}]]

comment Assumptions aren't working in this sum
I added the assumptions that alpha and beta are Real. So the sum should be real, but the result contains complex numbers: (-1)^4 or (1 + I) / Sqrt[2].

One motivation here is that if one can understand how mma computes the prediction then you can successfully export the svms generated by Classify.

That's a typo on my part should be exactly the same as before you're right.

These types of front end bugs are almost impossible to duplicate.

comment Frontend flickering
Hmmm, not sure why someone voted this to be closed, seems rather pertinent and huge bugs like these should be tracked historically.
