Abstract:
Deep Learning has recently caused very rapid advances in Artificial Intelligence, opening up unprecedented opportunities in machine learning. However, to date accuracy of deep learning systems can only be assessed statistically: they are essentially black boxes, meaning that their rationales for their decisions or predictions defy analysis. At the same time, they have been shown to display bias, and sometimes to hallucinate, i.e. to produce output that is not grounded in facts. In this presentation we will discuss recent results on the use of ontologies and deductive reasoning to understand the inner workings of trained deep learning systems.
