The recruited candidate is expected to develop a mathematical model and a software prototype for the application of contrastive learning to linking cognition and neuroimaging data.

Specifically

Introduction

The link between the human brain function, anatomy, and cognition remains uncharted territory. Brain imaging techniques, such as functional magnetic resonance imaging (fMRI) and diffusion magnetic resonance imaging (dMRI), provide in vivo information about neural activity and structural connectivity. However, linking these imaging modalities to cognitive functions poses a significant challenge. Specifically, current efforts for linking multivariate cognition measurements with neuroimaging are based on Partial Least Squares and Canonical Correlation Analysis techniques with poor out-of-sample generalization.

Deep Learning and Contrastive Learning

Within the deep learning field, contrastive learning, an emerging deep learning paradigm, has demonstrated remarkable success in unsupervised representation learning, particularly in the realm of natural language processing and computer vision.

Contrastive Learning Regression: An Open Field

While contrastive learning has garnered significant attention for its impressive performance in classification tasks, its application to regression problems remains unsolved. This presents an opportunity to expand the capabilities of contrastive learning and harness its potential in domains that demand continuous prediction, such as neuroimaging analysis.

Linking Brain Imaging and Cognition with Contrastive Learning Regression

The project will explore developing and applying contrastive learning regression frameworks to link fMRI and dMRI data with cognitive measures.

Mission confiée

Assignments :
With the help of D. Wassermann the recruited person will be taken to produce a deep-learning based system for the prediction of cognitive abilities from neuroimaging data.

The primary assignemnts forthis project are:

1. To evaluate current and develop novel contrastive learning regression frameworks for linking brain imaging data to cognitive measures and characterize their limitations.

2. To evaluate the performance of these frameworks on benchmark datasets, comparing their effectiveness to traditional regression approaches.

3. To investigate the interpretability of the learned representations and identify brain regions and structural connections associated with specific cognitive functions.

4. Co-coordinate PhD students and Interns with Demian Wassermann

5. Drive collaborations with the Laribosiere Hospital and Oxford University
