MVR generates and selects non-linear regression models. It was written in the Matlab language and intended to be used as an open-source code.
Introduction
This software is intended a curve-fitting tool. The models (curves) are generated using the set of primitive functions. More information on the algorithms could be found in the presentation, and in the paper. The complete documentation in English is coming. The fields applications are biology, physics, ecology, economics, etc.
Mathematical modelling has two issues: first, to create a model of a dynamic system using knowledge and second, to discover a model and knowledge using the measured data. So there are the model-driven and the data-driven approaches, and each one has its own strengths and weaknesses. The first one gives models that could be interpreted by experts in a field of application but usually they have poor prediction quality. The second one gives models of good quality but often too complex and non-interpretable by experts. The suggested approach gathers strong sides of these two: the result the model could be explained and it relies on the measured data. It allows getting the model with fair quality and generalization ability in comparison to universal models.
