Title: Multilinguality

Tanja Bäumel, DFKI

Tanja Bäumel is a researcher in the Multilinguality and Language Technology Lab at the German Research Center for Artificial Intelligence. She has a background in computational linguistics, computer science and cognitive science, and is currently pursuing her PhD. Her research is in the field of explainable artificial intelligence (XAI), where she works on understanding and interpreting the inner workings of large-scale pre-trained language models, as well as their limitations.

Title: Hands-on Lab on XAI

Simon Ostermann, DFKI

Simon Ostermann is lab manager, senior researcher and team lead at the Multilinguality and Language Technology lab at the German Research Center for Artificial Intelligence (DFKI). He holds a PhD in natural language processing from Saarland University (2020), on the role of general knowledge in the form of scripts in question answering. His research interests are in transparent and robust natural language processing; with the goal to (1) make the parameters and behaviour of language models more explainable and understandable and (2) to improve especially language models in terms of data consumption and size. He is coordinating and participating in diverse projects on the European and national level and a co-lead of the competence center on generative AI, established at DFKI in 2023.

Title: Hands-on Lab on XAI

Abstract: In this hands-on lab, participants will get hands-on experience in methods of Explainable Artificial Intelligence (XAI), which aims to enhance the transparency and interpretability of AI models. In the lab, participants will be introduced to selected methods and practical approaches of XAI, that help users to understand and trust their models’ decisions. Participants will engage in interactive sessions utilizing common XAI tools on real-world datasets and scenarios. We will specifically focus on explainable AI methods for natural language processing. By the end of the lab, participants will have a robust understanding of XAI principles and be equipped with practical skills to apply XAI techniques in their own AI projects.

Symeon Papadopoulos, CERTH

Dr. Symeon Papadopoulos is a Principal Researcher at the Information Technologies Institute, Centre for Research and Technology Hellas, Thessaloniki, Greece. He holds a PhD degree in Computer Science from the Aristotle University of Thessaloniki (2012) on the topic of Knowledge discovery from large-scale mining of social media content. His research interests lie at the intersection of multimedia understanding, social network analysis, information retrieval, big data management and artificial intelligence, where he has co-authored numerous journal articles, conference and workshop papers and book chapters. He has been participating in and coordinating a number of relevant EC FP7, H2020 and Horizon Europe projects in the areas of media convergence, social media and artificial intelligence. He is leading the Media Analysis, Verification and Retrieval Group (MeVer), and is a co-founder of the Infalia Private Company, a spin-out of CERTH-ITI.

Title of the talk: Introduction to Multimodal AI

Abstract: The talk will start by providing basic definitions of the main data modalities used in modern AI systems and will review a number of approaches for integrating different modalities in the design of an AI system. The talk will also present a number of relevant applications where multimodal AI is a key component. 

Stefanos-Ioardanis Papadopoulos, CERTH

Stefanos-Iordanis Papadopoulos is a Research Associate at the Information Technologies Institute (ITI) of the Centre for Research & Technology Hellas (CERTH). As a member of Media Analysis, Verification and Retrieval Group (MeVer), he has been involved in several EU-funded projects. His main research interests lie in the areas of multimodal deep learning, focusing on multimedia verification and retrieval, such as automated multimodal misinformation detection and fact-checking, where he has co-authored several conference and journal articles. 

Title: Hands-on Lab on Multimodal AI

Abstract: In this hands-on lab, we will delve into the fundamental concepts of multimodal deep learning. We will explore data preprocessing techniques, custom data loaders, neural network design and model training using Python and PyTorch. Participants will be called to implement and train deep learning models capable of detecting multimodal types of misinformation, namely out-of-context images and texts.

Ahmet Iscen, Google

Ahmet Iscen is a senior research scientist at Google. His area of expertise is developing methods for accurate and scalable image recognition in fine-grained, low-data and noisy-data settings, more recently using external tools and knowledge bases. His work has appeared in top-tier conferences, such as CVPR, ECCV, NeurIPS and ICLR . Previously, Ahmet worked as a postdoctoral researcher at Czech Technical University in Prague. He completed his Ph.D. degree at Université de Rennes I and Inria Rennes, and his PhD thesis received the Fondation Rennes 1 Best Thesis Award 2017 in the field of Mathematics, Sciences and Information and Communication Technologies..

Title of the talk: Fine-grained image recognition

Abstract: In this talk, I will present two of our recent works on fine-grained image recognition. In the first half of the talk, I will discuss how to equip existing vision-text models with the ability to refine their embedding with retrieved information from a knowledge memory at inference time, which greatly improves their zero-shot predictions. This is an alternative approach to encoding fine-grained knowledge directly into the model’s parameters; instead, we train the model to retrieve this knowledge from an external memory. In the second half of the talk, I will address web-scale visual entity recognition, specifically the task of mapping a given query image to one of the 6 million existing entities in Wikipedia. I will discuss our recent work “Generative Entity Recognition (GER)”, which, given an input image, learns to auto-regressively decode a semantic and discriminative “code” identifying the target entity.

Jakub Šimko, KInIT

Jakub focuses on the intersection of human computation, machine learning, and data synthesis. He has recently been working on data augmentation techniques, social media algorithm auditing, and misinformation modeling. He promotes interdisciplinary approaches to computer science research. Recently, he has been dedicating considerable effort to preparation of Horizon Europe grant projects. Jakub works on multiple national and international research projects and participated in several industry projects. He co-authored more than 40 publications, received more than 500 citations. Jakub is enthusiastic about creating online educational materials and has authored over 50 educational videos with lectures or tutorials.

Title of the workshop: Scientific Writing and Presentation

Abstract: In this tutorial, we will address the most severe pain points pertaining to the fine craft of scientific paper writing and presentation preparation. Many researchers (not only young ones), struggle with these latter academic disciplines, undercutting the impact of good research work they do. The tutorial will cover audience considerations, writing of effective outlines (of both papers and presentations), decomposition of thoughts, writing of efficient front matter, covering up for reader/audience sloppiness, preventing writer’s block, and more. The content will draw from two excellent books by Michael Alley: The Craft of Scientific Presentations and The Craft of Scientific Writing. Reading of these books before the tutorial will maximize the knowledge gain.
