Hello, I am trying to learn a model from a set of positive examples. A model being considered as made of several constraints, it looks much like a system of equations. I would like to represent each individual with several trees, each tree being the right inside of the equations forming the system. I guess using ADF is a good solution, but, I am not sure that is the best way to proceed... Is there any better way to proceed ? I have been implementing a simplified version of the problem with only one tree, which follows the example of tutorial 4. The whole thing work well to find a single equation. Now, what should I do to transform an example of regression such as tutorial 4 into something that finds let's say, a system of 3 equations with three variables ? Any suggestion would be greatly appreciated... Cheers! Mehdi
