Decision Trees for Monitoring Neural Networks
(Type: BT, Mentor: Sabine Rieder)
We want to explore the possibilities of using Decision Trees as a more understandable monitor for Neural Networks, potentially in combination with other monitors.

Yifei Xu:  A Framework for Evaluation of Runtime Monitors for Object Detection Neural Networks
(Mentor: Sabine Rieder)
While Object Detection Neural Networks are of high practical relevance, there is no standard way to evaluate them yet. In addition, not many monitors for this type of NN are known. In this thesis, we develop a framework to evaluate such monitors and present basic network monitoring methods.
