We have limited seats available only. No limits to sign up remotely! This event will be in English. ---- Talk #1 How to Hack an Agent – or Not Thomas Fraunholz Senior Researcher AI @ Smart Labs AI Large language models (LLMs) are not as secure as they seem. Beyond their tendency to “hallucinate,” they can be manipulated using jailbreaks and adversarial prompts, bypassing safeguards designed to keep them in check. But the real challenge arises when LLMs are connected to agents with real-world capabilities—like sending emails. This talk explores the security risks of AI agents and the ongoing research into making them more resilient. Using the "Adaptive Prompt Injection: LLMail Inject" challenge from the IEEE Conference on Secure and Trustworthy Machine Learning as a case study, we’ll examine how Microsoft’s Phi3 and OpenAI’s GPT-4o-mini handle adversarial attacks. We’ll break down security techniques like LLM judges, task drift detection, and prompt shields—critical concepts as the EU AI Act's security mandates take effect in August 2025. Attendees will gain insights into the strengths and weaknesses of current AI security mechanisms and learn practical strategies for assessing the safety of AI agents in production environments. About the Speaker Thomas is an MLOps and NLP expert with a background in applied mathematics and embedded programming. He has led two publicly funded AI research programs with the German Aerospace Center and is currently focused on AI-driven cybersecurity at Smart Labs AI GmbH. In his spare time, he’s developing a low-budget drone system for detecting bark beetle infestations, blending his passion for AI and embedded systems. Talk #2 AI & Data Strategy After NVIDIA GTC 2025: What You Need to Know Alexander C. S. Hendorf AI & Data Strategy and Implementation @ opotoc GmbH NVIDIA GTC is one of the most influential conferences in AI, showcasing advancements in accelerated computing, robotics, healthcare, and finance. In this talk, Alexander Hendorf will share his key takeaways from the conference, focusing on what’s most relevant for the community. From cutting-edge AI hardware and model optimization to real-world applications in robotics, healthcare, and financial modeling, we’ll explore how these technologies impact data workflows. Expect insights on practical AI adoption, the latest breakthroughs in GPU acceleration, and what’s actually useful (vs. just hype) for data scientists and engineers. About the Speaker Alexander is a data intelligence and AI expert with over 20 years of experience in digitalization and data-driven decision-making. As an independent consultant, he's specialized in AI & data strategy and implementation. A frequent speaker and chair at international conferences like PyCon DE, PyData Berlin, and EuroPython, he is also a Python Software Foundation Fellow and EuroPython Fellow. He serves on the board of the Python Software Verband and, since 2024, has also been leading Pioneers Hub, a non-profit dedicated to supporting tech communities. ---- Acknowledgements Also a big thank you to our partners: Hessian.AI, for hosting the meetup.

PyData Berlin 2024 August Meetup 2024-08-14 · 16:00 Welcome to the PyData Berlin August meetup! Please provide your first and last name, current role and organization name for the registration because this is required for the venue's entry policy. If you cannot attend, please cancel your spot so others are able to join as the space is limited. Host: Google Cloud is excited to welcome you for this month's version of PyData. Agenda: 6pm - 7pm: Arrival, networking and food & drinks (BBQ) 7pm - 9pm: Talks (and lightning talks) 9pm - 10pm: Drinks and networking ************************************************************************ The Lineup for the evening Talk 1: Multi-agent Systems with Mistral AI, Milvus and Llama-agents Abstract: Agentic systems are on the rise, helping developers create intelligent, autonomous systems. LLMs are becoming more and more capable of following diverse sets of instructions, making them ideal for managing these agents. This advancement opens up numerous possibilities for handling complex tasks with minimal human intervention in so many areas. In this talk, we will see how to build agents using llama-agents. We’ll also explore how combining different LLMs can enable various actions. For simpler tasks, we'll use Mistral Nemo, a smaller and more cost-effective model, and Mistral Large for orchestrating different agents. Speaker: Stephen Batifol Stephen is a Developer Advocate at Zilliz. He previously worked as a Machine Learning Engineer at Wolt, where he created and worked on the ML Platform, and previously as a Data Scientist at Brevo. Stephen studied Computer Science and Artificial Intelligence. He is a founding member of the MLOps.community Berlin group, where he organizes Meetups and hackathons. He enjoys boxing and surfing. Talk 2: Bayes by Hand Abstract: Discover how powerful Bayesian modelling can be with a pen and paper, or even in your head! Or - Bayes, the good bits! The focus is on Bayes as a thinking tool, rather than on code and algorithms. Think eliciting and updating priors, updating estimates rigorously with incoming data, etc. This approach reacts to the need for more disciplined estimation in business contexts, while wanting to include non-stats and non-dev stakeholders in the process. Bayes By Hand can be used for sketching out baselines, cross-disciplinary collaborations, improved decision making, and more. Let's get back to the blackboard my friends, and do some modelling by hand! Speaker: Laura Summers Laura is a very technical designer™️. She's the founder of Debias AI, (debias.ai) and the human behind Sweet Summer Child Score (summerchild.dev), Ethics Litmus Tests (ethical-litmus.site), fairXiv (fairxiv.org), the Melbourne Fair ML reading group (groups.io/g/fair-ml). Laura is passionate about feminism, digital rights and designing for privacy. She speaks, writes and runs workshops at the intersection of design and technology. Lightning talks There will be slots for 2-3 Lightning Talks (3-5 Minutes for each). Kindly let us know if you would like to present something at the start of the meetup :) * NumFOCUS Code of Conduct THE SHORT VERSION Be kind to others. Do not insult or put down others. Behave professionally. Remember that harassment and sexist, racist, or exclusionary jokes are not appropriate for NumFOCUS. All communication should be appropriate for a professional audience including people of many different backgrounds. Sexual language and imagery are not appropriate. NumFOCUS is dedicated to providing a harassment-free community for everyone, regardless of gender, sexual orientation, gender identity, and expression, disability, physical appearance, body size, race, or religion. We do not tolerate harassment of community members in any form. Thank you for helping make this a welcoming, friendly community for all.
