Explainable Artificial Intelligence: Interrogating the AI systems
Invited Talk - 7 November, 11:00-12:00, Julia House
Explainable AI (XAI) refers to methods and techniques in the application of AI technology such that the results of the solution can be understood by human experts. In this talk we will first argue about the necessity of XAI in the current technologically dependent world, and then we will mainly focus on one of the trickiest-to-be-explained part of AI, namely Machine Learning (ML). We will define the notions of Transparent and Black Box Models, we will discuss what constitutes explainable or interpretable Machine Learning and will analyze the dimensions of interpretability, types of data and the ways the Black Box ML models can be opened up. We will discuss several methodologies and implementation including one developed with our own laboratory. Finally, we will start scratching on the dynamics of argumentation for explainability, including some discussion on using argumentation for explanations in ML, as well as some ongoing work on using natural language to draft explanations for a logical argumentation framework based on Gorgias. Finally, a few things about two projects AI4EU (H2020) and SoCoLa (ΕΛΛΙΔΕΚ), where this work is based on, will be presented.
