Free Software

Over time we have written software related to data analysis, machine learning and optimization that we made free to use. Below are the links to the corresponding sourceforge sites:

A python visualization module for gain- and lift-charts with a one line visualization function:

A similar python visualization module for linear and logistic regression:

A python module to convert general (with non-numeric columns) spreadsheet tables into purely numeric tables. Often needed for data preprocessing in maschine learning applications:

A fortran-95 module to calculate the L1-norm (robust) linear regression coefficients.

A fortran-95 library for genetic algorithms:

Fortran-95 wrappers for Michael Powells global optimization routines that do not use derivatives:
