Professor ​Marco Comuzzi Description This lab focuses on the application of machine learning and computational intelligence techniques (e.g., classification/regression, deep learning, genetic algorithms and other evolutionary techniques, statistical anomaly detection) to the analysis of business process event logs. These are logs generated by the information systems that support the execution of business processes in organizations. We solve problems like predicting the outcome of the execution of business processes, predicting the activities that will be executed next in a process, or identifying anomalies in event logs, considering also the event streaming perspective.

Professor Gi-Soo Kim Description Our research interests are focused on statistical approaches to the sequential decision problem. The multi-armed bandit (MAB) problem formulates the sequential decision problem in which a learner is sequentially faced with a set of available actions, chooses an action, and receives a random reward in response. In our lab, we integrate online learning and optimization techniques to develop algorithms that efficiently learn the reward model while maximizing the rewards. We also apply the developed algorithms to real tasks such as recommendation systems and mobile health apps. We also use causal inference to evaluate the performance of multi-armed bandit algorithms in a retrospective way.

Professor Saerom Park Description Our research is focused on addressing the interconnected challenges of privacy, fairness, and security to promote the safe use of artificial intelligence (AI) algorithms in real-world systems. Our goal is to develop innovative solutions that enable privacy-preserving, fairness-aware, and security-enhanced machine learning. To achieve this goal, we are pursuing two key problem thrusts:

(i) We are developing comprehensive approaches to ensure the reliability of AI while considering security and privacy threats.

(ii) We are addressing the need for realistic threat models and evaluation for security-aware algorithms.

We are committed to advancing the field of artificial intelligence in a responsible and ethical manner. We believe that these three pillars are critical for building AI systems that are safe and beneficial for individuals, industry, and society.
