Machine Learning for aerospace engineers

Motivation, presentation and applications

OBJECTIVE :

This course aims to introduce the basics of machine learning, to put them into practice with the modern tools of data science (Python and R) and to show the benefit of these techniques for the aeronautical engineer.

COURSE DURATION AND TIMETABLE :

The course lasts 3 days and includes 11 hours of theory and 7 hours of examples and applications with a PC implementation via tutorials allowing the trainee to better integrate the methods taught. A time of implementation of the data methods provided by the trainees is planned.

Course in French, resources in English.

GENERAL APPROACH :

The deluge of data from the Web, the advent of generic computing on GPU and the incessant innovations presented by the big players of the Web led the majority of traditional industries to engage a so-called digital revolution. The aerospace sector is not excluded from this major trend. Nevertheless, to accompany this transformation towards data and machine learning, companies must train and recruit people trained in these areas so as to anticipate the benefits of these techniques but also to moderate the expectations that any industrial revolution generates. There are numerous new services that machine learning can create in the aeronautical sector: the predictive maintenance of aeronautical structures, the recommendation of contents for passengers, the automatic detection of manufacturing defects, the regression strategies of expensive digital simulation or the real-time detection of engine anomalies.

The purpose of this course is to present the basics of machine learning, its main techniques, its conventional and recent applications and potential ideas for applications in the aeronautics sector.  For many years, ONERA has been offering innovative machine learning applications in numerous aeronautical fields (pre-project design, digital simulation, image recognition, anomaly detection, etc.).

PREREQUISITE :

Course level: Basic/Advanced

Engineering training or equivalent required; basic statistical knowledge is reviewed at the beginning of the course. Knowledge of Python is not essential but would be a plus.
