Multi-Scale Texture Loss for CT denoising with GANs

1 code implementation25 Mar 2024 Francesco Di Feola, Lorenzo Tronchin, Valerio Guarrasi, Paolo Soda

To grasp highly complex and non-linear textural relationships in the training process, this work presents a loss function that leverages the intrinsic multi-scale nature of the Gray-Level-Co-occurrence Matrix (GLCM).

A Deep Learning Approach for Virtual Contrast Enhancement in Contrast Enhanced Spectral Mammography

no code implementations1 Aug 2023 Aurora Rofena, Valerio Guarrasi, Marina Sarli, Claudia Lucia Piccolo, Matteo Sammarra, Bruno Beomonte Zobel, Paolo Soda

Contrast Enhanced Spectral Mammography (CESM) is a dual-energy mammographic imaging technique that first needs intravenously administration of an iodinated contrast medium; then, it collects both a low-energy image, comparable to standard mammography, and a high-energy image.

A Deep Learning Approach for Overall Survival Prediction in Lung Cancer with Missing Values

no code implementations21 Jul 2023 Camillo Maria Caruso, Valerio Guarrasi, Sara Ramella, Paolo Soda

We present a novel approach to survival analysis with missing values in the context of NSCLC, which exploits the strengths of the transformer architecture to account only for available features without requiring any imputation strategy.

Multimodal Explainability via Latent Shift applied to COVID-19 stratification

no code implementations28 Dec 2022 Valerio Guarrasi, Lorenzo Tronchin, Domenico Albano, Eliodoro Faiella, Deborah Fazzini, Domiziana Santucci, Paolo Soda

The explanation of the decision taken is computed by applying a latent shift that, simulates a counterfactual prediction revealing the features of each modality that contribute the most to the decision and a quantitative score indicating the modality importance.
