I have used the Encog C# framework to create a neural network. The neural network is fully trained. So I would like to use the neural network in my main application to solve a subproblem.
Is there a way to export the neural network into my main application which is written in C++?
If you have such wish, then most straightforward way would be to convert C# code to C++ by yourself. That way actually isn't practical or achievable easy. So I propose you another way. From your C++ app use encog as .Net assembly. There are plenty of articles which explain how to call .Net assembly from C++.
