Title: Hybrid AI Systems for Transfer Learning using Knowledge Graphs

Transfer Learning (TL) is an area that has been core to machine learning research since before the deep learning hype. It is about generalizing a machine learning system to domains or tasks it has not been specifically trained for. With the rise of deep learning and embeddings considerable progress could be achieved in this area. In this talk I will focus on how knowledge graphs can be utilized to improve deep learning models. The primary application domain of hybrid AI systems proposed in this talk is visual object recognition. The talk will be concluded with the open research question on how foundation models and in-context learning contribute to transfer learning in general and what the role of knowledge-based hybrid deep learning systems might be in particular.

BIO: Prof. Rettinger’s interests lie in developing and applying deep learning language models for the extraction of information for building large knowledge graphs in different fields, where the latter in turn can be used as a basis for inference (both statistical and symbolic) of new knowledge (i.e. predicting new relations between graph entities, clustering nodes or categorizing entire networks). Currently, Prof. Rettinger collaborates strongly with LIRMM and the UM in building a Horizon EU project on AI for fighting disinformation.

Title: The Tortuous Road to Detecting and Countering Deception

Deception, or the intent to deceive is at the root of many of the grand challenges we are faced with as a society nowadays. From misinformation and disinformation to online manipulation and radicalization, deception always plays a central role. The question is, how can we identify deception and counter it? In this talk I will go through several approaches ranging from evidence-based fact checking to understanding the nuances of deceptive language and their application to different scenarios. Given the complexity of the challenge, we will touch upon different techniques involving symbolic, neural, and hybrid AI, language understanding, and knowledge graphs.

BIO: Dr. Peréz, a former Marie-Curie fellow, has a strong academic record in the field of AI and Semantic Web. Before, he worked as Director R&D at iSOCO, one of the first European companies to deliver semantic and natural language processing solutions on the Web. His current interests lie in bringing common sense knowledge (coming from structured knowledge resources) to statistical language models like BERT and GPT-3, explaining AI models and understanding and monitoring bias in data and algorithms.

Registration is free, but we would ask you to register in advance so that we can plan for breaks and lunch:…-ckxmpndi

We look forward to seeing you there!
