Sowmya Chandrasekaran gave a presentation on her PhD topic “A Novel Ranking Scheme for the Performance Analysis of Stochastic Optimization Algorithms using the Principles of Severity” at the doctoral colloquium “AI & Data Science”. The doctoral colloquium is an event of the department “Informatics and Data Science” of the doctoral college “PK NRW”.
The lecture took place on March 20, 2024 in the rooms of the Institute for Data Science, Engineering, and Analytics at the TH Köln, Campus Gummersbach.
S. Chandarasekaran is supervised by Prof. Dr. Thomas Bartz-Beielstein, Prof. Dr. Dietlind Zühlke, and Prof. Dr. Rainer Herpers. She has already published several papers on this topic on applications in the field of drinking water monitoring:
