Model aggregation: minimizing empirical variance outperforms minimizing empirical error

Published in Arxiv, 2024

We present a general framework to combine existing models in a robust manner. Our method is flexible, places few assumptions on the models aggregated, and performs well in our experiments Read more

Development and Assessment of an Artificial Intelligence-Based Tool for Ptosis Measurement in Adult Myasthenia Gravis Patients Using Selfie Video Clips Recorded on Smartphones

Published in Digital Biomarkers, 2023

My first paper ! This paper describes the work we did at Doc.ai for ShareCare on Myasthenia gravis (MG) with UCB. We devellopped a Deep Learning model based on ResNet50 to predict a key symptom of MG via selfie. This would allow clinical trials to accept more patients as part of a study in order to scale it, as well as follow almost in real time the evolution of a patients symptoms using an app on their phone.
