I've built some neural network using ANN_MLP java classes, everything works fine, excepts that I cant find any working method to save / load trained networks. I'm using opencv 3.1.0 in Java. I've tried the exposed ANN_MLP.save (String filename) method (inherited from Algorithm), but it crash the jvm, and for the loading there is nothing ! What are the right process to I/O trained networks ? Thanks.
