Discover the decision tree methods

In-house sessions

SPM® or Matlab® environment

1 day

Researchers, scientists and engineers


This training session on decision trees is intended for people wishing to:

  • Learn the basics of decision trees from Machine Learning
  • Analyze their own multivariate data at the end of the course
  • Be autonomous to use the data analysis software studied


During the training, the method principles are introduced by a geometric approach. Emphasis is placed on the practical use of the method and the interpretation of the results.

Application exercises are proposed for each method. The training can be held on different Chemometrics / Machine Learning software: SPM® (Salford Systems – Minitab), MATLAB® from The MathWorks.

    Metrohm involved Ondalys in many of their advanced trainings on chemometrics. As everyone knows this is not a topic of high entertainment value but here Sylvie Roussel and her team made a big difference! The interactive exchange during the training, the stories told to draw the picture behind the data and the down to earth work sessions helped everyone to get a much better understanding of the topic. In particular we are very happy that our cooperation help a lot to achieve the goals of the trainings. All participants confirmed the positive impact and like to see more in future.
