The Average Mixing Kernel Signature

1 code implementation ECCV 2020 Luca Cosmo, Giorgia Minello, Michael Bronstein, Luca Rossi, Andrea Torsello

We introduce the Average Mixing Kernel Signature (AMKS), a novel signature for points on non-rigid three-dimensional shapes based on the average mixing kernel and continuous-time quantum walks.

Graph Generation via Spectral Diffusion

no code implementations29 Feb 2024 Giorgia Minello, Alessandro Bicciato, Luca Rossi, Andrea Torsello, Luca Cosmo

In this paper, we present GRASP, a novel graph generative model based on 1) the spectral decomposition of the graph Laplacian matrix and 2) a diffusion process.

MUSTANG: Multi-Stain Self-Attention Graph Multiple Instance Learning Pipeline for Histopathology Whole Slide Images

1 code implementation19 Sep 2023 Amaya Gallagher-Syed, Luca Rossi, Felice Rivellese, Costantino Pitzalis, Myles Lewis, Michael Barnes, Gregory Slabaugh

Our approach is highly modular and can easily be modified to suit different clinical datasets, as it only requires a patient-level label without annotations and accepts WSI sets of different sizes, as the graphs can be of varying sizes and structures.

Graph Kernel Neural Networks

no code implementations14 Dec 2021 Luca Cosmo, Giorgia Minello, Michael Bronstein, Emanuele Rodolà, Luca Rossi, Andrea Torsello

The convolution operator at the core of many modern neural architectures can effectively be seen as performing a dot product between an input matrix and a filter.

Civil Wars: A New Lotka-Volterra Competitive System and Analysis of Winning Strategies

no code implementations30 Sep 2020 Elisa Affili, Serena Dipierro, Luca Rossi, Enrico Valdinoci

We introduce a new model in population dynamics that describes two species sharing the same environmental resources in a situation of open hostility.

GMNet: Graph Matching Network for Large Scale Part Semantic Segmentation in the Wild

no code implementations ECCV 2020 Umberto Michieli, Edoardo Borsato, Luca Rossi, Pietro Zanuttigh

To tackle part-level ambiguity and localization we propose a novel adjacency graph-based module that aims at matching the relative spatial relationships between ground truth and predicted parts.
