Probabilistic Graphical Models are a set of powerful techniques to represent and reason under uncertainty in artificial intelligence. After presenting an overview of graphical models, I will focus on Bayesian networks and causal models. Bayesian networks provide a compact representation of a joint probability distribution, including efficient methods for probabilistic reasoning and learning. We will cover some inference and learning algorithms, and illustrate their applications in medicine and industry. However, Bayesian networks are limited to represent associations, to go further and reason about interventions and counterfactuals we requiere causal models. I will give an introduction to causal graphical models and how to predict the effects on interventions and imagine alternative scenarios. We will cover causal discovery, that is learning cause-effect relations from data, and some applications in medicine and robotics. Finally, we will see how to combine reinforcement learning with causal discovery, to learn at the same time an optimal policy and a causal model.<\/p>\n\n\n\n

In the landscape of Artificial Intelligence (AI), the issue of social bias embedded within language models has garnered significant attention. In this talk, we will first discuss how language models represent context in order to understand how social biases get into these systems. We will delve into different definitions of context and how they affect grounding, intention, hallucinations, and prompting. With this background, we will discuss insights into the intricate dynamics of bias assessment in AI systems. With a human rights perspective, we will explore a fundamental question: Who holds the power to determine how language models discriminate? Through the proposal of an interdisciplinary and participatory approach, we will imagine a future in which power is distributed differently in language models.<\/p>\n\n\r\n\r\n\n

Short Bio:<\/strong> Luciana Benotti received a PhD in Computing from the Universit\u00e9 de Lorraine in France for her work on Natural Language Processing (NLP) at the Institut National de Recherche en Informatique et en Automatique (INRIA). She also has an Erasmus Mundus joint Masters degree in Computational Logics from the University of Bolzano in Italy and the Universidad Polit\u00e9cnica de Madrid, and a Masters in Computer Science from the Universidad del Comahue in Argentina.\u00a0 She served as the chair of the executive board of the Association for Computational Linguistics until January 2024 and is currently a member of the board. He has been an invited professor at the University of Stanford, US; Imperial College, London; INRIA, France; and CIMEC, Italy. She is currently an Associate Professor in Computer Science at the Universidad Nacional de C\u00f3rdoba and a researcher at the National Research Council in Argentina. She works with the NGOs Fundaci\u00f3n V\u00eda Libreto investigate NLP technology from a human rights perspective. Her research focuses on the areas of conversational agents, natural language processing, error and bias analysis in language models, and the social impact of artificial intelligence.<\/p>\n\n\r\n\r\n\n
