About Me

I am Hansol Yoon, a PhD student in Professor Sriram Sankaranarayanan’s group and the Computer Science department at the University of Colorado Boulder. Also, I am a Republic of Korea Air Force Major, and I worked at the Avionics Software Development Center in the Korean Air Force before coming to the US.

My research focuses on runtime verification with applications in autonomous systems.

Semantic Anomaly Detection through Property Templates

We investigate the problem of detecting anomalous behaviors of deployed autonomous vehicles that are not consistent with “typical” or “baseline” behaviors. Detecting anomalies requires us to process large volumes of high dimensional data from on-board sensors including GPS, camera, LiDAR and RADAR. In this project, we propose a simple methodology of runtime monitoring through “property templates” that allow us to detect meaningful anomalies of interest to stakeholders, while at the same time reducing from a very high dimensional space to a lower dimensional space through the property templates. Next, we use Pareto frontiers to define anomalous instances in the data with respect to the property.
