General software features
  • Supervised Classification
  • Unsupervised Classification

for quantitive and qualitative data.

To address issues of data classification, Mixmod uses mixture models, powerful and flexible tool.

Among the many features and tools available in Mixmod:

  • Processing quantitative data (with Gaussian mixture models) or qualititative (with Multinomial mixture models)
  • Parsimonious mixture models
  • Specific models for the treatment of high-dimensional data (individuals characterized by a large number of features)
  • EM, CEM, SEM Algorithms
  • Many strategies initialization
  • Criteria for selection of models and the number of classes suited to different purposes
Context in which the software is used

The Mixmod software package consists :

  • a library (C++): mixmodLib
  • a Graphical User Interface: mixmodGUI developed with QT : mixmodGUI
  • functions for R: RMixmod
  • functions for Matlab: mixmodForMatlab
