Hi, I really like Alglib and I enjoy using its many functions. One of the things I'm looking into is saving a trained classifier. I use the random forest classifier quite extensively. However, the one thing I do not like about it is the required training time which is much longer than the classification time in my application. I was wondering if it is possible to somehow save the trained classifier to disk so I could just load it straight into memory and start classifying. I'd appreciate any tips you could give me.

Thanks Mr. Bochkanov for your wonderful library....

It can be problematic - as of 3.2, ALGLIB doesn't support serialization of complex data structures. Serialization was planned for a 3.3, but I suspect that it will wait for 3.4 at best.

Hi.
In my application I use the neural network from C# and I have to store a trained networks. I did a copy of the alglib mlpbase.multilayerperceptron (with litle changes). Then I marked all fields with xml serialization attributes. And now I can serialize my network and store it in the any type of storage.
Before using this lib you should create a good adapter I think.
