Pascal Hitzler, endowed Lloyd T. Smith Creativity in Engineering Chair at the Department of Computer Science at Kansas State University and Director of the Center for Artificial Intelligence and Data Science (CAIDS), will present "Explaining hidden neuron activations using Semantic Web methods."
Pascal Hitzler is a Professor and endowed Lloyd T. Smith Creativity in Engineering Chair and Director of the Center for Artificial Intelligence and Data Science (CAIDS) at the Department of Computer Science at Kansas State University. He is director of the Data Semantics (DaSe) Lab. In 2001 he obtained a PhD in Mathematics from the National University of Ireland, University College Cork, and in 1998 a Diplom (Master equivalent) in Mathematics from the University of Tübingen in Germany.

Deep Learning has recently caused very rapid advances in Artificial Intelligence, opening up unprecedented opportunities in machine learning. However, to date accuracy of deep learning systems can only be assessed statistically: they are essentially black boxes, meaning that their rationales for their decisions or predictions defy analysis. At the same time, they have been shown to display bias, and sometimes to hallucinate, i.e. to produce output that is not grounded in facts. In this presentation we will discuss recent results on the use of ontologies and deductive reasoning to understand the inner workings of trained deep learning systems.

We continue the CIRSS speaker series in Fall 2023 with a focus on “Knowledge Graphs and Semantic Computing”. We will meet on Fridays, 9-10am Central Time, on Zoom. To join a session, go to the current week’s session and click the “access” link, which will lead you to a calendar entry. There, click the “PARTICIPATE online” button to join a session. Recordings of past talks can be found next to "access" if available. The event is open to the public, and everyone is welcome to attend! This series is hosted by the Center for Informatics Research in Science and Scholarship (CIRSS). If you have any questions, please contact Jana Diesner and Halil Kilicoglu.
