Technically, the internship relates to computer vision, and more precisely to image classification for the field of tourism. In collaboration with research engineers from the CEA, the aim will be to study the feasibility of self-supervision for deep parameter-frugal models, to train such models and to evaluate their use in the PROPEOS application framework. . The internship is designed as an introduction to research and will aim to publish a scientific article if the results obtained are convincing. This initial work could be continued in a thesis, within a broader framework.
