starting point as it defines the characteristics and specifications of these techniques.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u201chuman- in-the-loop (HITL)\u201d, because the human plays an important role in the improvement of AI systems;<\/li>\n\n\n\n<li>distributed because data are usually generated in a distributed manner as in the case of federated learning scenarios, as a function of where the service provider and consumer are located;<\/li>\n\n\n\n<li>\u201cdynamic\u201d because data continuously evolve in time.<\/li>\n<\/ul>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>It is crucial to monitor the process by which previous data are managed and exploited for analysing the data generated during the current time slot via methods like time-aware learning. <em>Expand to read more<\/em>.<\/summary>\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By HITL, we mean techniques where there is a continual bidirectional human-machine interaction and where the human can spontaneously provide information. These would include different scenarios such as tagging a photo, reporting information about the human\u2019s current activities, or the human and the machine engaging in a discussion because the machine thinks that the human has provided wrong information, e.g. mislabeling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Contrarily, such an exchange could also occur when the human needs to fix the machine&#8217;s reasoning that leads to a wrong conclusion. The HITL approach can be adopted in all four main ML phases (i.e., data collection, data pre-processing, model training, and model execution).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The enforcement of this HITL approach motivates our choice of using Knowledge Graphs (KGs) as a more abstract and knowledge-level representation of tabular or Internet of Things (IoT) data. Indeed, KGs enforce the move from variables (or at most tabular data) to entities, from features to data properties describing entities and to object properties describing relations and actions among entities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In turn, LLMs, optionally fed by KGs, provide an even further level of abstraction. This becomes key where the end-user is not an expert such that entities, their properties and relations are explained to the user in natural language, also making explicit a huge amount of common- sense knowledge that they embed.<\/p>\n<\/details>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"has-small-font-size wp-block-paragraph\" style=\"font-style:normal;font-weight:100;text-transform:uppercase\">AMBITIONS<\/p>\n\n\n\n<details class=\"wp-block-details is-style-default has-base-2-background-color has-background is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Ambition 1.1<\/strong>. We will study how to adopt the HITL approach at different levels of abstraction, from IoT sensors and features to data and object properties as embedded in KGs, where KGs will facilitate the user in the reuse of past data as well as data generated by third parties up to the interaction.<\/summary>\n<p class=\"wp-block-paragraph\">The proper level of data abstraction will be tuned to the specific task and application scenario with the possibility of using two representation models (e.g., features and KGs), mutually reinforcing themselves in a meaningful interaction with the user. We will develop Personal KGs (PKGs) encoding the user\u2019s subjective perspective on the world, and we will integrate this into KGs to encompass a multi-user perspective.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This will require the development of Temporal KGs (TKGs) and Spatio-Temporal KGs whenever there is a need to integrate IoT data. It is worth noting that Knowledge Graphs (KG) operate on two levels: the schema KG (SKG) and the data KG (DKG). The reliability of KG-based reasoning heavily depends on the quality of the SKG. If the SKG is flawed, any reasoning or explanations derived from it\u2014whether concerning entities, time, or relationships\u2014will be inaccurate, regardless of the data&#8217;s correctness. Current literature reveals a lack of theoretical and principled approaches in this area. To address this, our project will leverage techniques from information science. This approach will not only support a multi-dimensional representation of knowledge (known as facets) but also provide the flexibility needed to incorporate and update new facts and knowledge within the KG.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-style-default has-base-2-background-color has-background is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Ambition 1.2<\/strong>. We will analyse different steps, from local to global, by which data are first generated and then used to train and use ML models.<\/summary>\n<p class=\"wp-block-paragraph\">The ultimate goal is to integrate robustness solutions and evaluate their impact on the performance and accuracy of the AI systems and hence the trade-off between their trustworthiness and accuracy. We will concentrate on two main techniques, that is, how to distribute in time and space the data generation and preparation, and federated learning for what concerns the model training and usage.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-style-default has-base-2-background-color has-background is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Ambition 1.3<\/strong>. We will develop a robust and adaptable federated continual learning framework capable of effectively addressing spatial-temporal catastrophic forgetting in resource-constrained environments.<\/summary>\n<p class=\"wp-block-paragraph\">The framework will be designed to enhance communication efficiency, handle model heterogeneity, and explore alternative sharing modes. Through rigorous validation in diverse real-world scenarios, including healthcare, IoT, and finance, we will demonstrate the practical effectiveness of our approach. One fundamental focus will be on applying federated learning across individuals, for instance, with the goal of doing cross-individual activity recognition. A second fundamental focus will be on federated learning and temporal adaptation in the design of this framework.<\/p>\n<\/details>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\" style=\"font-style:normal;font-weight:100;text-transform:uppercase\"><a href=\"#obj-overview\">Back to overview <\/a><\/p>\n<\/div>\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide wp-container-content-9cfa9a5a\" style=\"margin-top:var(--wp--preset--spacing--40);margin-bottom:var(--wp--preset--spacing--40)\"\/>\n\n\n\n<div class=\"wp-block-group alignwide has-base-2-background-color has-background has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\" id=\"obj-2\" style=\"border-top-left-radius:40px;border-top-right-radius:40px;border-bottom-left-radius:40px;border-bottom-right-radius:40px;padding-top:var(--wp--preset--spacing--40);padding-bottom:var(--wp--preset--spacing--40)\">\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"has-small-font-size wp-block-paragraph\" style=\"font-style:normal;font-weight:100;text-transform:uppercase\">Objective 2<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Trustworthiness through robustness<\/h2>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"has-small-font-size wp-block-paragraph\" style=\"font-style:normal;font-weight:100;text-transform:uppercase\">description<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The performance of AI technologies relies on access to large datasets of good quality and on the training of an accurate model. Hence, AI systems\u2019 dependence on large data makes them vulnerable to adversarial attacks that can manipulate inputs or model parameters in order to tamper with the training process. Such attacks may be hard to detect because the manipulated model is designed to exhibit adversarial behaviour on inputs which usually are only known to the attacker. The literature features various proposals to mitigate poisoning attacks. Nevertheless, these solutions usually work with neural networks and sometimes require considerable and computationally heavy modification to existing algorithms.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"has-small-font-size wp-block-paragraph\" style=\"font-style:normal;font-weight:100;text-transform:uppercase\">AMBITIONS<\/p>\n\n\n\n<details class=\"wp-block-details is-style-default has-base-2-background-color has-background is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Ambition 2.1<\/strong>.
