This should only be given to someone with a fair understanding of the topic.
There are several options, as I tried to say in my initial post: 1) bindings for an existing structured SVM. 2) bindings for a smart solver with structured svm code by us 3) using SGD for solving. This means "having our own SVM solver" -- but we already got one in SGDClassifier. 4) write a solver using cutting plane or bundle methods (not quite sure if this is a good idea) From my point of view 1) would be most desirable, though it is not quite clear how possible it is. 2) and 3) are definitely good options. 4) is probably to much for a GSoC project. Having this feature might get us a LOT of attention.
