"What is Neurosymbolic AI?"
Abstract: Neurosymbolic AI seeks to bridge the strengths of neural networks and symbolic AI to overcome fundamental limitations of each approach when used in isolation. This talk provides an accessible introduction to the field, clarifying core concepts and distinguishing modern neurosymbolic methods from earlier hybrid attempts -- or perhaps noting how they are not so different. We will critically examine why this integration is urgently needed today: deep learning’s data hunger, lack of robustness, opacity, and struggle with causal or relational reasoning contrast sharply with symbolic AI’s brittleness in uncertain, real-world environments—and neither alone suffices for trustworthy, generalizable AI. The discussion will then pivot to the current state-of-the-art gaps, highlighting key challenges such as enabling gradient-based learning of symbolic structures, scaling complex reasoning, or achieving true generalization, as well as domains well-suited the approach, such as healthcare, robotics, and scientific discovery. This will equip early researchers with both the foundational understanding and awareness of open problems in the field.
Biography
Cogan Shimizu is an assistant professor of computer science at Wright State University, in Dayton, Ohio, where he directs the Knowledge and Semantic Technologies (KASTLE) laboratory. Shimizu's research program focuses on the development of knowledge graphs (KGs) and ontologies, primarily using pattern-based and modular design, including their use in and alongside large neural systems (i.e., neurosymbolic AI). The lab also develops methods and resources for teaching knowledge engineering.
Previous to this, he was a a Postdoctoral Researcher in the Data Semantics Lab at Kansas State University. A full breakdown of his research can be found on KASTLE lab's Website.
