Title: Limitations and New Frontiers in Deep Learning and its Applications to Data Science
Date & Venue: 29/04/2024, 11h. Salón de Grados 101, Departamental II, URJC Móstoles
Abstract: The advent of deep learning (DL) models has seen neural networks being successfully applied across many classification and prediction problems with implications especially in the areas of image and video, or text and speech processing and analysis. Since its (re-)emergence in 2009 deep neural networks have consistently replaced state-of-the-art approaches to machine learning and largely overcame the problem of hand-crafted feature extraction that dominated to little avail the field precedently, for over 50 years. One of the key enablers of DL models is the availability of compute, yet, although scale has proven to be a definitive driver in building increasingly better performing models, neural nets still exhibit serious vulnerabilities and erroneous behavior in terms of brittleness, spurious correlations, lack of interpretability, or more recently, hallucinating misinformation. In this talk I will set-out by identifying a few key underlying limitations in the deep learning literature, as well as addressing shortcomings of machine learning techniques more broadly. Following, I will point towards several research directions by reflecting on contributions from my previous and ongoing research. The presentation will focus on approaches showcased across various application domains of DL to Data Science problems including computer vision, natural language processing and internet of things settings.

Title: Smart Services, Explainable AI, and smart visualizations
Date & Venue: 08/05/2024, 10:30h. Room 062, Departamental I. FCEE, URJC Vicálvaro
Abstract: Today, we have technology that must work for the people’s benefit. We must continue to learn how to intertwine science, technology, and innovation in our fast-growing service-oriented economy, where we deal with people-centric interactions. These interactions are more and more mediated by technology, can be described in complex actor networks, the service ecosystems, and develop in service systems, that integrate people, technology, and shared information. These interactions are more and more "informed" by rich data-driven processes and the citizens are experiencing them more and more through the smart service ecosystems. Therefore, we have the incentives now to better understand, describe, and innovate in complex, service-oriented systems like healthcare, business organizations, government agencies, and cities. And we have the possibility to formulate new value propositions for our society with the new tools that the human mind has created. While AI will always remain artificial because it will always be a product constructed out of the human mind, we cannot deny the potentialities of these new technologies/algorithms to help people do their jobs better or to improve people’s lives. However, there is a growing need for these new technologies to be better explained to increase the degree of acceptance at all levels of society and by all the relevant stakeholders. We want to see a better adoption of AI-type technologies, as this can bring a lot of benefits to society, companies, and individuals. But we need to increase the trust in their decision-building process and create a kind of explainability regarding law compliance, robustness and reliability in operation, and trustworthiness. In this respect, this presentation proposes a journey in the smart service design process, where AI explainability and smart visualization can bring the process of decision-making closer to the most important recipient of this endeavor, the smart citizen.

Title: Explainable Reinforcement Learning for Large-Scale Applications
Date & Venue: 27/09/2024, 11h, Salón de Grados 101, Departamental II, URJC Móstoles
Abstract: RL has seen major breakthroughs in the recent years and is extensively investigated in a range of practical applications, including those within city-scale infrastructures. However, existing algorithms still fall short of being suitable for a wider use in such complex environments. My research focuses on developing techniques that enable the use of RL for optimization in large-scale adaptive systems, for example, communication networks and intelligent mobility. These systems share properties with many other large-scale systems, i.e., are characterized by distributed control, heterogeneity, presence of multiple and often conflicting goals, reliance on diverse sources of information, and the need for continuous adaptation. In this talk I will discuss a range of techniques we have developed for enabling RL use in such environments, such as multi-agent multi-objective optimization, state space adaptation in non-stationary conditions, and online transfer learning. In particular, I will focus on explainability of RL systems (XRL), as a crucial element required for ensuring trustworthiness of RL-based systems. I will discuss differences required in explaining RL systems compared to other types of XAI, and present our approaches to generating and evaluating counterfactual and semi-factual RL explanations. I will conclude the talk by discussing further challenges in enabling RL deployments in large-scale systems, including further development of algorithms to ensure seamless lifelong adaptivity and highlighting the need for scalable explainability, interactive RL, and testing techniques for RL-based applications.

Title: Networks, networks, and more networks: applications in humanities, data science, and machine learning
Date & Venue: 17/10/2024, 9:30h, URJC Móstoles, Salón de Grados 101, Departamental II
Abstract: It is known that networks or graphs can be used in machine learning and data science to represent and analyze data that has complex relationships. Besides, networks are also relevant to the overall AI agenda in at least two aspects. First, it relates to automated data gathering and language models in the semantic web, since the actual data have to be acquired in some manner in order to form the graphs. Second, it can be used to accelerate learning tasks, as in the case of reinforcement learning. In this talk I present examples of how data is acquired and used in applications in the Humanities (history, storytelling) in order to discover patterns and/or to investigate assumptions. Then, I discuss applications on data science and machine learning, as for instance the use of networks in reinforcement learning, with examples from urban mobility and car to infrastructure communication.

Title: AI and Simulation: a composite relationship
Date & Venue: 17/10/2024, 11:15h, URJC Móstoles, Salón de Grados 101, Departamental II
Abstract: Results of AI are apparent and they triggered legitimate research questions on potential implications on many different fields. A recent Gartner hype cycle reports the topic “AI Simulation” in the "innovation trigger” phase, with a growing expectation for results in a 2 to 5 years timeframe. The relationship between simulation and AI, however, is not new: AI has already been used in different phases of a simulation project, sometimes within simulation models, but also for analysis of data describing real world dynamics, or simulation results. This talk will discuss a general framework of simulation projects, presenting concrete cases in which the paths of simulation and AI have already crossed, trying to conclude with some lessons learned and lines for future developments.

Title: Explicitness for Credibility of Agent-Based Simulations
Date & Venue: 17/10/2024, 12:30h, URJC Móstoles, Salón de Grados 101, Departamental II
Abstract: Agent-based simulation can be seen as a well-established application of multi-agent systems. Yet, one still experiences hesitation in accepting agent-based approaches in decision support or in some scientific domains. Are there still challenges for credibility of models and simulation results? In the presentation, I will discuss those and talk about a number of approaches developed to enhance the explicitness of the model, exemplified by a economic model analyzing dynamics of technology uptake in manufacturing services.
Short Bio: Franziska Klügl is Professor in Computer Science at the School of Science and Technology of örebrö University, Sweden. Her main research interests are related to languages, processes and tools for multi-agent systems, in particular when applied to simulation modeling.

Title: Value-alignment and its applications in policy-making
Date & Venue: 14/11/2024, 11:30h, URJC Móstoles, Salón de Grados 101, Departamental II
Abstract: With the advancement of AI, it has become paramount that we ensure it behaves and makes decisions in line with our moral values and priorities. This problem, called value-alignment, presents two main challenges: to formalise values mathematically, and to show how they can be used to regulate behaviour. In this seminar, we will see how we can address these challenges. First, we will define moral values in a computer-readable way based on the ethics literature. Second, we will explore the use of value-aligned norms to regulate agent behaviour. We will also show how these two contributions can easily be adapted for value-aligned decision making. Finally, we will illustrate how this theoretical research can be of practical use in policymaking, in particular for participatory budgets, processes where citizens propose and decide how to spend a government-defined budget. Value-alignment techniques can resolve issues like low participation, underrepresentation of minorities, and under-funding.
