Debug mode of DBN C++ code leads to equal results

[carterbao]

While changing from debug mode to release in Visual Studio makes the correct result. So where is the problem?

I got it, in the HiddenLayer(int size, int in, int out, double **w, double *bp) construction function, after b = new double[n_out]; each element of b should be initialized to zero, otherwise they will be randomly initialized to be too large in debug mode. However in release mode, they are initialized to small values.
