Vibrational Spectroscopy Conference (GFSV) – May 2018 – Le Ventron, France

 Ondalys participates to the 24th spectroscopic conference of the French Group of Vibrational Spectroscopy (GFSV)

This conference, which addresses the theme of vibrational spectroscopies as tools of expertise, will take place in Ventron (Vosges) in France, from May 16 to 18, 2018.

Dr. Sylvie Roussel from Ondalys will speak about : Comparison of Machine Learning methods for spectroscopic data analysis.


From some years, the terms “Machine learning” and “Artificial Intelligence (AI)” have been increasingly used. But what do these methods of Machine Learning cover compared to the methods of “Chemometrics” or Spectroscopic Data Analysis?

In this lecture, different methods of data analysis and machine learning for spectrum analysis are described and compared for a near infrared (NIR) spectroscopy application:

  • Transformation of the original variables and PLS models
  • Local model (locally located regression – LWR)
  • CART / Random Forest (Random Forest – RF)
  • Support Vector Machine (SVM)
  • Artificial Neural Networks (ANN)

Machine Learning for Vibrational Spectroscopy data analysis.


As every year, this conference aims to promote technological developments in spectroscopies. This is an opportunity for academics, manufacturers and equipment manufacturers to discuss and share their vision of the future for f infrared spectroscopy (IRTF), near-infrared spectroscopy (NIRS) and Raman spectroscopy.
