Detection of subclinical atherosclerosis by image-based deep learning on chest x-ray

no code implementations27 Mar 2024 Guglielmo Gallone, Francesco Iodice, Alberto Presta, Davide Tore, Ovidio de Filippo, Michele Visciano, Carlo Alberto Barbano, Alessandro Serafini, Paola Gorrini, Alessandro Bruno, Walter Grosso Marra, James Hughes, Mario Iannaccone, Paolo Fonio, Attilio Fiandrotti, Alessandro Depaoli, Marco Grangetto, Gaetano Maria de Ferrari, Fabrizio D'Ascenzo

A deep-learning algorithm to predict coronary artery calcium (CAC) score (the AI-CAC model) was developed on 460 chest x-ray (80% training cohort, 20% internal validation cohort) of primary prevention patients (58. 4% male, median age 63 [51-74] years) with available paired chest x-ray and chest computed tomography (CT) indicated for any clinical reason and performed within 3 months.

Contrastive learning for regression in multi-site brain age prediction

no code implementations14 Nov 2022 Carlo Alberto Barbano, Benoit Dufumier, Edouard Duchesnay, Marco Grangetto, Pietro Gori

Building accurate Deep Learning (DL) models for brain age prediction is a very relevant topic in neuroimaging, as it could help better understand neurodegenerative disorders and find new biomarkers.

Unbiased Supervised Contrastive Learning

1 code implementation10 Nov 2022 Carlo Alberto Barbano, Benoit Dufumier, Enzo Tartaglione, Marco Grangetto, Pietro Gori

In this work, we tackle the problem of learning representations that are robust to biases.

Integrating Prior Knowledge in Contrastive Learning with Kernel

1 code implementation3 Jun 2022 Benoit Dufumier, Carlo Alberto Barbano, Robin Louiset, Edouard Duchesnay, Pietro Gori

To this end, we use kernel theory to propose a novel loss, called decoupled uniformity, that i) allows the integration of prior knowledge and ii) removes the negative-positive coupling in the original InfoNCE loss.

Unsupervised Learning of Unbiased Visual Representations

no code implementations26 Apr 2022 Carlo Alberto Barbano, Enzo Tartaglione, Marco Grangetto

We propose a fully unsupervised debiasing framework, consisting of three steps: first, we exploit the natural preference for learning malignant biases, obtaining a bias-capturing model; then, we perform a pseudo-labelling step to obtain bias labels; finally we employ state-of-the-art supervised debiasing techniques to obtain an unbiased model.

EnD: Entangling and Disentangling deep representations for bias correction

2 code implementations CVPR 2021 Enzo Tartaglione, Carlo Alberto Barbano, Marco Grangetto

Artificial neural networks perform state-of-the-art in an ever-growing number of tasks, and nowadays they are used to solve an incredibly large variety of tasks.

A two-step explainable approach for COVID-19 computer-aided diagnosis from chest x-ray images

no code implementations25 Jan 2021 Carlo Alberto Barbano, Enzo Tartaglione, Claudio Berzovini, Marco Calandri, Marco Grangetto

Early screening of patients is a critical issue in order to assess immediate and fast responses against the spread of COVID-19.

Unveiling COVID-19 from Chest X-ray with deep learning: a hurdles race with small data

9 code implementations11 Apr 2020 Enzo Tartaglione, Carlo Alberto Barbano, Claudio Berzovini, Marco Calandri, Marco Grangetto

The possibility to use widespread and simple chest X-ray (CXR) imaging for early screening of COVID-19 patients is attracting much interest from both the clinical and the AI community.
