Internship - Deep learning with noisy labels in histopathology (start september-october 2023)

Primaa est une start-up medtech développant des logiciels d’aide à la prise de décision dans le diagnostic de cancer.

Les outils que Primaa développe s’adressent aux médecins anatomo-pathologistes, dans le but de les assister face à l’augmentation constante du nombre de cancers, et ainsi réduire le temps de diagnostic pour améliorer les chances de survie des patients.

Pionnière dans son domaine, Primaa bénéficie d’un soutien fort de l’écosystème médical.

Context

Most of the time, accurate diagnosis of cancer requires a histological examination. It consists of analyzing a tissue sample so as to confirm the presence of a tumor, qualify the type of lesion detected and, thus, adjust the therapy.

At primaa, we have developed deep learning based methods to classify lesions, detect biomarkers and segment regions of interests. Those models are trained on labeled data that can be noisy. We want to explore various training strategies designed to overcome this limitation [1].
