title: Target values for neural network
body: <p>I've been using MATLAB's neural network toolbox to generate good for character recognition. I wanted to develop my own to compare against and also try and use different methods for weight updates. I've got the network to return only values between 0 and 1. I was wondering how I can adapt this so that the network returns say 1, 2, 3, 4; numbers corresponding to rows in my data matrix, where each row is a different letter.</p>
