Reviewed the source of neural network data analysis algorithm. During testing it noticed that the default parameter values are quite different for neural networks and neural ensemble networks, and I wonder if this was on purpose. Additionally the ensemble network parameter values yield rather poor results (tested on poly-10 and default classification problem) compared to standard neural networks.
