Download free GRADIENT and MEMFIS for Research Use

This is the page to download Gradient and MEMFIS. Both are very powerful regression systems, which use grammar-guided genetic programming. Gradient produces ensembles of neural networks and support vector machines, while MEMFIS uses a memetic approach to calculate precise Takagi-Sugeno neuro-fuzzy systems. More information on Gradient can be found here, and for MEMFIS can be found here.

Both systems have been produced as part of the EU-funded project INFER. In addition, I received funding (senior research fellowship) by the Marie Skłodowska-Curie Actions - European Commission.

Gradient and MEMFIS are provided as standalone Windows applications (they should run without problems to any 32-bit Win system, e.g. XP,Vista,7,8 and 10, presumably to 64-bit too, but this is not yet tested).

You may use freely Gradient and MEMFIS for your research, and freely publish your results, using the following citation(s):

What is included in the download files

Each download file contains a directory with the regression system executable (and any supporting files), and another directory where a 'Profiler' software exists, that allows to update the parameter files (e.g. it's just a one-page software menu with data entries, so you don't have to manually update - and guess - the numbers included inside the parameter files). The systems have been 'tuned' to default/preferred settings. Use any other setting at your own risk. The download file contains also several DOS batches which will execute run/search on some default public domain data/problems. I recommend you run first the batches so you get an idea. Then install the Profiler, and open one "syspar" file, so you get another idea on the tuning. At first, it is recommended that you keep the default settings for your problem and start tweaking only when you feel you may improve the results. The programs create sub-directories and files, so make sure you have admin rights on the chosen directories.
