Eureqa: software review

The Eureqa software, also called the robot scientist was developed at the Computational Synthesis Lab at Cornell University by Dr. Hod Lipson. It uses symbolic regression for detecting equations and hidden mathematical relationships in raw data. The software was used to map the relationship between real measured values and values calculated according to manufacturer's manual. Radon measurements were taken in a house in the Czech Republic over 5 weeks. Five datasets of 26 measured values were obtained. The data was easily entered into Eureqa using its spreadsheet like interface. Next Eureqa requires the function set to be chosen, so addition, subtraction, multiplication and division, together with both Gaussian and exponential functions were chosen. Eureqa also supports parallel operation over multiple computers. Eureqa splits automatically training and validation dataset. The user can choose the amount of training or validation data or use the default settings.
