  1. 151. Laplacian lens on complex and signed networks and the onset of the spin glass behavior
    A. Gabrielli
    16/09/2025, 09:30

    Heterogeneous and complex networks represent the intertwined
    interactions between real-world elements or agents. Determining the
    multi-scale mesoscopic organization of clusters and intertwined
    structures is still a fundamental and open problem of complex network
    theory. By taking advantage of the recent Laplacian Renormalization
    Group [1-4] approach , we scrutinize information diffusion...

  2. 152. Topic modelling methods for the analysis of multi-omics data
    M. Caselle
    16/09/2025, 10:00

    Topic models are a set of algorithms originally developed to extract latent variables from texts corpora. The most popular of these algorithms is the so-called Latent Dirichlet Allocation (LDA) which has been successfully applied in these last years not only in texts analysis but also in bioinformatics. In fact algorithms which try to identify the ``topic'' of a given document from the word...

  3. 153. Archetypal Decomposition of Metagenomic Profiles for Cross-Study Diagnostic Classification
    M. Seppi
    16/09/2025, 10:30

    Shotgun metagenomics enables the quantitative profiling of microbial communities in biological samples, providing a rich, high-dimensional description of microbiota composition. These microbial profiles are increasingly used to investigate associations with host health. However, the high dimensionality of such data—thousands of microbial or functional features per sample—and the heterogeneity...

  4. 154. Machine-enhanced reconstruction of functional connectomes unravels discriminative brain sub- systems in health and disease
    S. Grassia
    16/09/2025, 10:50

    The human brain is a complex system of 100 billion neurons, each one connected on average to 10,000 other neurons to exchange
    electrochemical information. It is possible to coarse-grain this system by considering the average activity of large neuronal aggregates
    into Regions of Interest (ROIs), acting as fundamental areas in functional Magnetic Resonance Imaging (fMRI), and their...
