    Representation learning on knowledge graphs: embedding models and applications

    No full text
    In this work the research activities and the results obtained in the development of machine learning solutions to support inclusive digital storytelling activities based on Knowledge Graph within the European project MEMEX, founded by the European Union's Horizon 2020 research and innovation programme under grant agreement No 870743, will be presented. In particular we are going to investigate the impact of the best performing embedding state-of-the-art models in the link prediction task of MEMEX Knowledge Graphs on the ability to extract node partitions in an unsupervised context. This is motivated since an important principle for representational learning is that the representations should benefit learning algorithms to exploit commonalities between different learning tasks to share statistical strength and transfer knowledge across tasks. In our experiments we observed the limits of Knowledge Graph embedding models in learning representations that share this properties across different tasks (Link Prediction and Clustering) and promising results consideraing information beyond the participation of entities and relationships in plausibility of facts

    Gruppi di permutazione

    No full text
    Partendo dai rudimenti passando per la teoria dei gruppi questo lavoro raggiunge la teoria dei gruppi di permutazione in un percorso che permetta la comprensione e la dimostrazione che il gruppo alterno di grado maggiore o uguale a cinque sia semplice. L'intento dell'autore dando un taglio, per quanto possibile, divulgativo alla trattazione è quello di offrire tutti gli strumenti necessari al raggiungimento della tesi ricompresi in un unico testo

    Synthesis and characterization of printable bioinks: gelatin methacrylate composite hydrogels for 3d culture

    No full text
    This work is focused on the synthesis, characterization and validation of semisynthetic hydrogels with a gelatin base of animal origin, functionalized with methacrylic groups. A combination of different materials, both natural and synthetic, with gelatin methacrylate is also investigated. These composite materials will be used as biocompatible inks for printing three-dimensional structures in order to study Neuroblastoma tumor cells in a 3D environment
