Java Aptitude Questions & Answers - Java Basic Input & Output. When gradients in the neural network get suffficiently large, that would propagate back through the network, causing the weights to spiral out of control if unchecked. There is some literature on multi-output regression (good summary here), but these involve scales of predicting high dimensional vectors(or even matrices), rather than just 3 numbers, so I don't know how useful this literature would be for your case, but that's where I would look if you're insistent on having a single model predict 3 outputs. In the following example, an SVM script is used to predict the purchase of bikes based on a customer's income and number of children.
