AI-based improvement of the evaluation of side view sonar images using deep learning methods

The dissertation by Dr Yannik Steiniger deals with how deep learning models for the evaluation of side view sonar images can be successfully trained even with little training data. Among other things, a method for generating synthetic sonar images is presented and it is shown that enriching the training data set with these images can significantly increase the classification performance of neural networks.

Bottom-up Knowledge Graph-based Data Management, André Pomp, 2020

In this paper, a novel approach called Bottom-up Knowledge Graph is introduced, aiming to enhance semantic data management in enterprises by addressing the challenges posed by traditional ontology engineering in handling (semi-)structured data sources. Additionally, a semantic data platform (ESKAPE) is developed to demonstrate the benefits of the proposed approach.
