Add Clustering & Bi-Clustering Performance Benchmarks

[michaelweylandt]

We should add some benchmarks indicating the advantages of convex (bi)clustering over classical methods. Depending on the run-time, these can be a vignette or just included as a "run for yourself" file.

@jjn13 I believe you had some of these from early experiments. Could you share? If you email them to me, I'll work them up into a vignette.

Hi @jjn13,

Any updates on this?
