Welcome!

In 2000, the Signal Processing and Speech Communication Laboratory (SPSC Lab) of Graz University of Technology (TU Graz) was founded as a research and education center in nonlinear signal processing and computational intelligence, algorithm engineering, as well as circuits & systems modeling and design. It covers applications in wireless communications, speech/audio communication, and telecommunications.

Learning a Behavior Model of Hybrid Systems Through Combining Model-Based Testing and Machine Learning [link]

Models play an essential role in the design process of cyber-physical systems. They form the basis for simulation and analysis and help in identifying design problems as early as possible. However, the construction of models that comprise physical and digital behavior is challenging. Consequently, there is considerable interest in learning the behavior of such systems using machine learning. However, the performance of the machine learning techniques depends crucially on sufficient and representative training data covering the behavior of the system adequately not only in standard situations, but also in edge cases that are often particularly important.
