CDD Ingénieur de Recherche en Machine Learning, 18 mois, équipe SIAM IBISC/Projet SONDES


A research engineer position is opened at IBISC-lab ( starting from October 2022. for 18 months.

As part of the SONDES project, we are looking for a research engineer (Candidate Master Science, BAC+5), beginner or confirmed, for a CDD of at least 18 months with a very good background in mathematics and computer science; a strong personal interest in machine learning is also mandatory.

Keywords: deep learning, multi-modal imaging, weakly supervised learning

Research topics related to the SONDES project

  • machine learning to predict the quality of measurements and detect defects
  • data visualization
  • image and signal analysis
  • domain shift
  • data augmentation

Scientific topics

Basic AI and Data Science : high-dimensional statistical learning

Specialized ML and AI : signal, image, vision

Application domain : non-destructive control, ultrasound sensors

Scientific Description

Non-destructive testing (NDT) is one of the components of « advanced manufacturing ». Control during maintenance, to detect material defects, check the conformity of welds, etc.

This work concerns the identification by deep neural networks of possible fat defects in a critical system. The identification of these defects will be based on several ultrasonic measurements, carried out in situ by the maintenance teams of the various partner industrial sites.

The objectives of this study are

  1. (main): Be able to recognize in (at least) 95% of cases, bolts with a « corrosive stress crack » or « fatigue crack » type defect
  2. Develop explanatory algorithms to visualize the elements that had a preponderant weight in the decision taken by the model to classify a bolt as defective.
  3. Expand the training set to reduce modeling uncertainty (epistemic uncertainties) by training our model on many more measurements, but whose labeling might be less reliable or absent (semi-supervised learning).


Laboratory: IBISC (University of Evry, University of Paris-Saclay)

Team: IBISC /SIAM is a team dedicated to artificial intelligence and cybersystems. IBISC is particularly involved in precision medicine, evaluation and patient care, and personalized medicine.

Total duration of the internship: 18 months or more

Remuneration: 2600€ /month

Starting date: October 1st 2022

Ending date: Feb. 26Th, 2024


Master’s degree in one of the following fields, or a closely related domain:

– computer science

– mathematics and statistics

– engineering
