The 3rd CAIML Symposium, held on May 6, 2024, brought together leading experts and enthusiasts in the field of Artificial Intelligence and Machine Learning. The symposium aimed to discuss the latest advancements, challenges, and opportunities in these domains. Attendees enjoyed a day filled with insightful talks, engaging discussions, and networking opportunities.

The symposium commenced with welcome addresses from Jasmin Gründling-Riener, Vice Rector Academic Affairs, and Georg Sedlbauer from the Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation, and Technology - BMK. Following the opening remarks, the iCAIML Doctoral College and Cluster of Excellence for Bilateral AI (BILAI) were presented, which aim to study the innovative combinations and applications of AI and ML.

Participants engaged in a series of scientific talks and a panel discussion, which provided insights into current trends and future directions of AI research and stimulated discussion regarding these trends and developments. The event also included opportunities for networking, allowing attendees to connect and exchange ideas.

AI, Fast and Slow

By Martina Seidl


In general awareness, the field of artificial intelligence is closely associated with sub-symbolic AI, especially with machine learning. In almost every aspect of daily life, we currently experience fundamental changes that are triggered by ML technology. This kind of AI is good in processing huge amounts of (statistical) data and, if trained accordingly, make decisions fast and with astonishing adequacy.

In a more silent manner, the symbolic branch of AI also has a strong influence on the modern world. Symbolic techniques play an important role in building correct hardware and software systems whose complexity would not be manageable without them and they are applied to solve complex planning, scheduling, and configuration problems.

In this talk, we show some prominent applications of symbolic AI and explain the underlying solving approaches with focus on SAT solving. We also argue that building broader AI systems as possible today is only possible by combining the best of symbolic and sub-symbolic AI.

Learning and Reasoning for Trustworthy AI

By Luc De Raedt

The abilities to learn and to reason are central to (artificial) intelligence. The focus in AI today is very much on learning, but one should not learn what one already knows. The challenge therefore is to use the avaible knowledge to guide and constrain the learning, and to reason with the resulting models in a trustworthy manner. This requires the integration of different paradigms for AI (such as logic, probability and neural networks), which is the focus of neurosymbolic AI, often viewed as the next wave in AI.

The talk will contrast traditional AI techniques (such as search and rule-based AI) with those of deep learning and large language models. I will argue that we need to combine the best of both worlds to arrive at trustworthy AI, especially AI that exploits knowledge, provides genuine explanations and guarantees with regard to safety and robustness.

The view of Neurosymbolic AI as Logic + Probability + Neural Networks, will allow me to specify a high-level recipe for developing neurosymbolic AI approaches: start from a logic, add a probabilistic interpretation, and then turn neural networks into ‘neural predicates’. Probability is interpreted broadly here, and is necessary to provide a quantitative and differentiable component to the logic. At the semantic and the computation level, one can then combine logical circuits (aka proof structures) labeled with probability, and neural networks in computation graphs.
