The research group "Reliable Machine Learning" studies the properties of machine learning algorithms. In view of the recent success of deep learningmethods in applications like image recognition, speech recognition, and automatic translation, the group especially focuses on properties of deep neural networks.
Although a neural network trained e.g. for an image classification task might work well on "real inputs", it has been repeatedly shown empirically that such networks are vulnerable to adversarial examples: a minimal perturbation (impercetible to a human) of the input data can cause the network to misclassify the input. Thus, an important research area of the group is to mathematically understand the reasons for the existence of such adversarial examples (i.e., the instability of trained neural networks), and - building on that understanding - to develop improved methods that yield provably robust neural networks.
Last week, Prof. Nadja Ray, in her role as Deputy Women's Representative of the MGF, invited female Data Science students to tea time at the Georgianum. The event, which takes place once a semester, is intended to promote exchange among female DS students, establish contacts across the year groups and also offer a safer space in which problems etc. can be addressed.
