Inauguration of Paderborn University’s new high-performance computing centre
On Friday, 29 April, Paderborn University celebrated the official opening of its new high-performance computing centre which houses the “Noctua 2” supercomputer.
The roughly 340-square-metre computer hall, home to the HPC (High Performance Computing) system and its possible expansion,
is at the heart of the research building.
"With more than 140,000 latest generation AMD Milan CPU processor cores and particularly powerful Nvidia A100 graphics card accelerators,
we are increasing our existing computing power tenfold. This takes us into a completely new order of magnitude,
enabling even the most demanding computer simulations in the natural, material and engineering sciences.
In computer systems research, too, we are setting a focus on research and infrastructure that is unique in Europe by further expanding the computer partition with particularly energy-efficient, programmable FPGA-based hardware accelerators," explained Professor Christian Plessl, Chairman of the Board of PC2.
Hybrid Lecture by Humboldt Professor Yaochu Jin on April 27, 16:15-17:45 CET, "Towards Evolutionary Developmental Artificial Intelligence"
Together with the Faculty of Technology of Bielefeld University, the JAII will co-host the inauguration lecture by Prof. Yaochu Jin. The lecture will be a hybrid event, taking place in the CITEC lecture hall (located on the ground floor of the CITEC) and online via Zoom.
Prof Jin is an Alexander von Humboldt Professor for Artificial Intelligence (endowed by the German Federal Ministery of Education and Research) at the Faculty of Technology, Bielefeld University. His main research interests include data-driven evolutionary optimization, multi-objective optimization, evolutionary learning, secure and privacy-preserving machine learning, and evolutionary developmental systems. Prof Jin is presently the Editor-in-Chief of the IEEE TRANSACTIONS ON COGNITIVE AND DEVELOPMENTAL SYSTEMS and the Editor-in-Chief of Complex & Intelligent Systems. He was named by the Web of Science as “a Highly Cited Researcher” in 2019 and 2020.
Considering the limitations of the deep learning approach to artificial intelligence, this talk proposes to understand and emulate human intelligence from an evolutionary developmental perspective.
We first provide a brief introduction to the biological findings about evolution and development of human brain and nervous systems.
Then preliminary computational models of neural and morphological evolution and development are presented.
Experimental results reveal that energy minimization is a main principle behind the organization of nervous systems and there is a close coupling between body and brain in evolution and development.
Finally, we describe some recent advances in computational modeling of neural plasticity embedded in the reservoir computing and discuss their influences on the learning performance of echo state networks and spiking neural networks.
The talks is concluded by an outline of future research.

Strengthening the regional network for AI research: project SAIL is being funded!
North Rhine-Westfalia funds five research networks with a total of 81 Million Euros. One of those networks is SAIL,
"Sustainable Life-cycle of Intelligent Socio-Technical Systems".
SAIL builds on existing collaborations between Bielefeld and Paderborn University, the University of Applied Sciences Bielefeld, and the OWL University of Applied Sciences and Arts.
The aim of SAIL is to strengthen interdisciplinary research ties in core AI, engineering, and the social sciences and humanities, as well as establishing a strong transfer chain from basic research to industry applications.
As a central node of the research network, the JAII will play an important role in SAIL, and we are looking very much forward to the begin of the project in Summer.

JAII Lecture by Prof. Michael Beetz on the 10th of March, 16:00-17:30 CET, "Knowledge representation & reasoning in CRAM"
We continue the JAII Lecture Series with a talk by Prof. Dr. Michael Beetz (University of Bremen, head of the Institute for Artificial Intelligence).
He will talk about "Knowledge representation & reasoning in CRAM - a cognitive architecture for robot agents accomplishing everyday manipulation tasks."
Robotic agents that can accomplish manipulation tasks with the competence of humans have been one of the grand research challenges for artificial intelligence (AI)
and robotics research for more than 50 years. However, while the fields made huge progress, this ultimate goal is still out of reach. I believe that this is the case
because the knowledge representation and reasoning methods that have been proposed in AI so far are necessary but too abstract. I propose to address this problem by
endowing robots with the capability to internally emulate and simulate theirperception-action loops based on realistic images and faithful physics simulations,
which are made machine-understandable by casting them as virtual symbolic knowledge bases. These capabilities allow robots to generate huge collections of
machine-understandable manipulation experiences, which robotic agents can generalize into commonsense and intuitive physics knowledge applicable to open varieties
of manipulation tasks. This will equip robots with an understanding of the relation between their motions and the physical effects they cause at an unprecedented
level of realism, depth, and breadth, and enable them to master human-scale manipulation tasks.

JAII Lecture by Prof. Max Welling on the 10th of February, 16:00-17:30 CET, "The Impact of Deep Learning on the Natural Sciences"
We continue the JAII Lecture Series with a talk by Prof. Dr. Max Welling. He will talk about "The Impact of Deep Learning on the Natural Sciences".
Abstract: Deep learning has significantly changed the fields of speech recognition, computer vision and natural language processing, to name a few. What’s next? We are currently witnessing fast progress in the application of deep learning to scientific computation, such as protein folding, weather prediction, and molecular simulation. In this talk I will discuss a number of important tools and concepts that are pushing the frontier of this new disruption. In particular I will discuss graph neural networks for the prediction of molecular properties and the numerical integration of PDEs, and flows for molecular synthesis. We also discuss the important concept of incorporating symmetries in these models through equivariant layers. We will end with some thoughts on the impact on sustainability and health that these new breakthroughs might enable.
Max Welling is a research chair in Machine Learning at the University of Amsterdam and has various other positions, such as serving on the founding board of ELLIS.

Update: JAII Lecture Series with Kristian Kersting, "Making Deep Machines Right for the Right Reasons" postponed
The Lecture by Prof. Kristian Kersting (AIML lab @ TU Darmstadt) in January had to be postponed. We will try to reschedule the lecture.
Abstract: Deep neural networks have shown excellent performances in many real-world applications. Unfortunately, they may show “Clever Hans”-like behavior—making use of confounding factors within datasets—to achieve high performance. In this talk, I shall touch upon explanatory interactive learning (XIL). XIL adds the expert into the training loop such that she interactively revises the original model via providing feedback on its explanations. Since “visual” explanations may not be sufficient to grapple with the model’s true concept, I shall also touch upon revising a model on the semantic level, e.g. “never focus on the color to make your decision”. Our experimental results demonstrate that XIL can help avoiding Clever Hans moments in machine learning. Overall, this all illustrates the benefits of a Hybrid AI, the combination of neural and symbolic AI.
The talk will be a virtual event. Please register here to receive the Zoom link:
Inauguration lecture by Yaochu Jin postponed

Colloquium with Marius Lindauer on Efficient and Explainable AutoML on November 11! (virtual and in person)
First talk in JAII colloquium series: We are looking forward to a talk by Prof. Dr. Marius Lindauer, professor of machine learning at the Leibniz University of Hannover, on November 11, 16.15-17.45h.
Abstract: Automated machine learning (AutoML) supports developers by determining appropriate machine learning pipelines (incl. feature pre-processing, predictive model selection and hyperparameter optimization) and thus contributes towards achieving peak performance on a given machine learning task. However, we cannot ignore that humans are involved in the development of new machine learning applications. So, we have to strive for both, efficient AutoML and explainable AutoML.
This talk will first cover state-of-the-art techniques for AutoML, proposing a new technique for local Bayesian optimization, and how AutoML leads to new state-of-the-art performance on tabular datasets by using well regularized deep neural networks. In the second part of the talk, I will argue that full automation of machine learning design without any humans in the loop is not what developers are looking for, and propose ideas along the lines of explainable AutoML. Both together will not only lower the entrance barrier and increase performance of machine learning, but also of AutoML.
The talk will be a hybrid event, either join us in person in lecture hall H4, Bielefeld University main building or online via Zoom. Registration is necessary to either receive the Zoom link or to attend in person; the "3G" rule applies for the in-person event.

Chatbot developed at Paderborn University assists in data analysis
The “Intelligent Data Science Chatbot” project has developed a chatbot to simplify data analysis for users. The aim of the intelligent chatbot, developed within the scope of a research project by Prof. Dr. Axel Ngonga’s DICE group at Paderborn University, is to allow users to evaluate large data volumes quickly and easily. As a rule, more expensive tools, programming skills, and experts are required for this purpose, which is a cost factor that should not be underestimated, particularly for small and medium-sized enterprises. Created as a web-based platform, the chatbot helps users perform independent analysis of their data.
Successful virtual kick-off of the JAII with over 100 participants
September 15th 2021 marked the kickoff of the Joint Artificial Intelligence Institute of the Bielefeld and Paderborn universities. Participants included the president of Paderborn and the rector of Bielefeld University, the founding members of the institute, as well as national and international guests.
Prof. Dr. Gerhard Sagerer, rector of Bielefeld University, and Prof. Dr. Birgitt Riegraf, president of Paderborn University, both stressed the importance of AI research for their university and the complementary expertise of both universities, as evidenced by several existing collaborations, also including the universities of applied sciences FH Bielefeld and TH OWL. Prof. Dr. Philipp Cimiano, co-director of the institute, sketched the core mission of JAII: He argued that the goal to pursue human-centered AI is about more than designing AI systems for humans, it is about establishing long-term partnerships where humans can dynamically shape the interface, process and outcomes of AI systems. The invited speaker, Prof. Dr. Frank van Harmelen from the VU Amsterdam, presented strengths and weaknesses of the traditions of symbolic and statistical AI, as well as new approaches to integrate both traditions, which was followed by a lively discussion of the potential of such approaches.
Kick off for the JAII with a talk by Frank van Harmelen on September 15
We are happy to announce the kick off event for the JAII, which will feature a greeting by the president of Paderborn University and rector of Bielefeld University, the director of the JAII and a talk by Prof. Frank van Harmelen, Vrije Universiteit Amsterdam.
Title: "How to build AI systems that both learn and reason?".
Abstract: Truly intelligent systems will have to both learn from experience and reason with acquired knowledge. Progress in the two fields of knowledge representation and machine learning has lead to an explosion of publications on how to build hybrid, "neuro-symbolic" systems that combine the techniques from this hitherto separate fields, with hundreds of new proposals appearing in the literature in recent years. In this talk I will describe a modular approach to such neuro-symbolic systems that allows us to re-interpret and systematize this rapidly growing literature on "3rd wave AI" system.
A strong network for sustainable AI: Participation in "Netzwerke 2021" call
Bielefeld University and Paderborn University, together with the Bielefeld University of Applied Sciences and OWL University of Applied Sciences and Arts have participated in the "Netzwerke 2021" call of the MKW NRW. With their application, the universities plan to further strengthen their exisiting research ties by developing machine learning techniques for the entire life cycle of intelligent technical systems. This shifts attention from technological requirements, which are particularly prominent in the introduction phase, to societal and human needs, which are impacted by the long-term operation of intelligent technical systems. Insofar as the application is successful, the JAII would become the organizational hub of the project, facilitating the dissemination of best practices across all four collaborating universities.
