The AI in dynamic action (AIDA) scientific group is dedicated to the study and application of artificial intelligence in dynamical environments, with a special focus on safety and trustworthiness. Among various machine learning approaches, we are especially interested in reinforcement learning - a methodology resembling the action of living beings in changing, uncertain environments which react by punishment and reward. Applied to human economy, AI has to fulfill requirements on safety and trustworthiness, especially regarding the personal data privacy. These requirements become particularly challenging in dynamical application of AI, such as robotic, autonomous driving, medical therapy support, chemical engineering, energy management etc. The scientific group seeks to apply an interdisciplinary approach by the fusion of machine learning with various fields, such as system and control theory, to develop novel dynamic AI methods.
