- rename positivity_constraint to negativity_constraint - or flip some signs!
- implement customized kkt solver for inner qp (should we?)
- make tests faster:
- use OneSlackSSVM more in tests
- constraint pruning in n-slack SSVM
- finish multilabel
- missing examples:
- handwritten sequence classification example
- more chain CRFs - POS tagging?
- submodular CRFs - segmentation?
- make more examples plot examples
- replace pairwise tri code with scipy.spatial.squareform
- in subgradient ssvm: Decouple updates from shrinking w (aka commulative penalty).
- remove EdgeTypeGraphCRF
- allow for warm starts in inference during learning
