Learning from unlabeled data

Interactive Labeling

The Machine Learning approaches, which are currently perceived as successful, are in many cases based on supervised learning.
To train such models, large amounts of labeled data are required. The provision of the labels is a major challenge which often prevents the application of ML in productive environments where labels are not necessarily available. While proposing different approaches, the following underlying research question is addressed:

How can we efficiently label training data with an interactive interplay of ML model and expert knowledge ?
