Catégorie : Stagiaire


Enhancing disease prediction using Deep Learning

Lieu de stage: SIMOB - IBISC (EA 4526) - Univ. Paris-Sacay (UEVE)
Contact: dominique.fourer@univ-evry.fr
Salary an perspectives: According to background and experience (a minimum of 577.50 euros/month). Possibility to pursue with a 3-year-funded PhD contract with international research partners.

Abstract:
Since the last decade, interest for arti cial intelligence (AI) has grown thanks to recent advances in the eld of machine learning [1, 6]. Deep learning provides a new class of biological inspired methods (neural networks) which spectacularly outperforms most of the previously existing techniques in the field of computer vision. This internship investigates how to adapt an ecient deep learning architecture for biomedical images recognition and disease detection. The motivating application is an automatic system that can detect thrombus from brain scanner images.

Goals:

Methodology:
The study focuses on convolutional neural networks (CNN) which have proven their efficiency in the field of computer vision [5]. An e ffort will be made to find the best architecture for the proposed classi cation task of biomedical for disease prediction.
From a theoretical point of view, we expect to better understand the role of the architecture and of the optimized loss function to provide the best prediction results. Possible approaches to cope with an insufficient amount of data may use variational auto-encoder (VAE) [2], generative adversarial networks (GAN) [3] and data augmentation techniques [4].

An evaluation protocol with its corresponding testbench will be proposed to objectively compare an arbitrary number of techniques for a given annotated dataset. A comparison with a given baseline method is expected in order to validate the e ffectiveness of the new proposed enhancements measured in terms of recognition rate.
