Teams of Genetic Predictors for Inverse Problem Solving

Michael Defoin Platel, Manuel Clergue, Philippe Collard

Genetic Programming (GP) has shown to be a good method to predict functions that solve inverse problems. In this context, a solution given by GP generally consists in a sole predictor. In contrast, Stack-based GP systems manipulate structures that allows to evolve together several predictors, that can be considered as teams of predictors. Work in machine learning reports that combining predictors gives good result in both quality and robustness. In this paper, we use Stack-based GP to study different ways to realize cooperation between predictors. First, preliminary tests and parameters tuning are performed on an academic GP benchmark. Then, the system is applied to a real inverse problem. A comparative study with standard methods has shown limits and advantages of teams prediction; in particular, when combinations take into account the response quality of each team member.
