Dear All, We submitted Sparta/Safair relevant paper to Entropy journal of MDPI. Title: Can Humans Understand Machines? The Principles and Advantages of Explainable Artificial Intelligence By: Szczepanski, Choras, Pawlicki, Pawlicka. Abstract: Since its creation, Artificial Intelligence has found innumerable applications and become ubiquitous in everyday lives. Increasingly, intelligent systems are being trusted with decision making; from making unnoticeable, minor choices to determining people’s fates, e.g. as part of predictive policing. This fact raises serious concerns about the explainability of the systems, that is constructing the solutions is such a way that enables humans to comprehend their results. This paper introduces the concept of Explainable Artificial Intelligence (xAI), along with its principles and methodology. Then, it proposes the general taxonomy of the xAI solutions, followed by an overview of some of the market products that utilize it. If accepted we plan to acknowledge SPARTA. Kind Regards, Prof. Michal Choras
