Dear All, I would like to use spark ml to develop some project related with optimization algorithm, however, in spark 1.4.1 it seems that under ml's optimizer there are only about 2 optimization algorithms. My project may needs more kinds of optimization algorithms, then how would I use spark ml to develop it? And for the given optimization algorithm, it would be with different constraint conditions (math formula), exactly how would I actualize & solve those complex math formulas in the optimization algorithm? If there are some comments, or some examples / links, it would be much useful.I must appreciate your help very much! Thank you,Zhiliang
