In diesem Kurs beschäftigen wir uns mit verschiedenen Texten aus unterschiedlichen Bereichen. Das können u.a. kurze Geschichten, Gedichte, Zeitungsartikel, Kolumnen oder Videos sein. Immer sind es Themen, die uns gefallen, die wir besonders interessant, wichtig oder manchmal auch richtig schlecht finden. Gemeinsam versuchen wir die Position der Autor*in, den Stil und die Argumentationsstruktur zu verstehen. Dazu diskutieren wir über das, was wir verstehen, welche Meinung wir zu dem Thema haben oder welche Fragen offen bleiben.
Gerne könnt ihr uns auch Themenvorschläge mitbringen oder zuschicken.
Der Kurs richtet sich an interessierte Menschen mit einem B2-Niveau (oder so ähnlich), die Lust haben sich weiter mit der deutschen Sprache zu beschäftigen und ihren Wortschatz zu erweitern.
Die Termine sind sporadisch.

**Join the FINALE of the free BLISS AI Speaker Series Winter 2025/26!** We are excited to feature **Ahmed Salem**, who is currently a Researcher at **Microsoft Security Response Center (MSRC)** and will discuss **"The Price of Intelligence: Three Risks Inherent in LLMs**", lasting approximately 45 minutes. After the talk, seize the opportunity to connect with fellow AI enthusiasts to share ideas and questions while enjoying free drinks and pizza. **Door close by 7.15pm, so please come early! Also, "attend"ing (RSVP) here on Meetup is strictly necessary to be guaranteed entry.** Please note that Meetup has recently been quite keen on promoting its Plus program. However, you are not obligated to purchase it, as both our events and the platform remain free. **Who is this event for?** This event is open to everyone interested in state-of-the-art AI research. We especially design it for students, PhD candidates, academic researchers, and industry professionals with a research focus in machine learning. **Abstract**: As LLMs move from passive assistants to action taking agents, the price of intelligence is increasingly paid in control failures: what the model treats as instruction, how behavior shifts across time and context, and how fragile safety properties can become under downstream adaptation. In this talk, we begin with indirect prompt injection as an end‑to‑end problem, where untrusted content can steer downstream actions in realistic pipelines. We then discuss a defense direction that secures agent planning through deterministic policy enforcement and principled control over what information is exposed during planning. Finally, we turn to a practical question that underlies all of these results: how do we know when an agent/LLM is actually safe, rather than merely scoring well on an evaluation? We highlight two factors that can systematically distort safety measurement in agent settings. First, reasoning models can change compliance when they infer they are being evaluated (“test awareness”), which can bias apparent robustness and complicate safety audits. Second, we discuss implicit memory as a hidden channel that challenges the “stateless” assumption and enables temporal behaviors that standard evaluation setups may fail to surface. **Bio**: [Ahmed](https://ahmedsalem2.github.io/) is a Researcher at the Microsoft Security Response Center (MSRC), focusing on machine learning privacy, biomedical data privacy, and applied cryptography. He was previously a Postdoctoral Researcher at Microsoft Research Cambridge (2022–2024). He received his PhD in Computer Science from CISPA Helmholtz Center for Information Security, Saarland University, under the supervision of Michael Backes and Yang Zhang, graduating *summa cum laude*. Before that, he earned his MSc in Computer Science from Saarland University with high honors and his BSc in Digital Media Engineering from the German University in Cairo. His work has appeared at ICML, USENIX Security, CCS, NDSS, and Oakland. We are [BLISS](https://bliss.berlin/) e.V., the **AI** **organization** in Berlin that **connects like-minded individuals** who share great interest and passion for the field of machine learning. This winter 2025/26, we will, again, host an exciting speaker series on site in Berlin, featuring excellent researchers from Tübingen AI Center, DeepMind, Microsoft, King's College London, cohere, and ETH Zürich.

Welcome to the PyData Berlin February meetup! We would like to welcome you all starting from 18:00. There will be food and drinks. The talks begin around 18.30 and the doors will close at 18:45. **Make sure to arrive on time!** Please provide your first and last 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**: **GetYourGuide** is excited to welcome you to this month's version of PyData. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* The Lineup for the evening **Talk 1: How Data (Science) is Transforming Professional Sports** **Abstract**: From Moneyball's linear regression revolution to AlphaGo's Move 37, data science has fundamentally reshaped how we understand and play sports. This talk explores three key dimensions of this transformation: first, how analytics revolutionized scouting and training—from the Oakland Athletics' 20-game winning streak to Liverpool FC ending their 30-year championship drought through data-driven player selection. Second, how machine learning and real-time tracking systems have changed gameplay itself, making the mid-range jump shot obsolete in basketball and revealing chess strategies that had eluded grandmasters for thousands of years. Finally, we'll examine the darker consequences, including how ML-powered microbetting has transformed sports gambling into a $149 billion industry that resembles slot machines more than traditional wagering. This talk offers insights spanning baseball, soccer, basketball, chess, and Go - demonstrating how data science doesn't just optimize existing strategies, it fundamentally questions the assumptions entire sports were built upon. **Speaker**: Kaan Isik **Bio**: Kaan Isik is a Data Scientist at GetYourGuide where he works on the Activity Ranking team. As a member of this team, he focuses on developing and optimizing the learn-to-rank deep learning model that powers real-time activity recommendations for millions of travelers worldwide. His work directly impacts how users discover activities across GetYourGuide's platform, making their travel planning more personalized and efficient. **Talk 2: Can Foundation Models outperform classic ML on structured data? Hands-on experience with TabPFN** **Abstract**: LLMs excel at generalising over text data, but cannot reliably predict outcomes from spreadsheets and databases, which drive most critical decisions across medicine, finance, science and virtually all industries. In this talk, we will showcase how TabPFN, Tabular Foundation Model developed by Berlin-based Prior Labs, successfully generalises over structured data problems, beating classic ML with win rates ranging from 100% to 87%. **Speaker**: Diana Kriuchkova **Bio**: Diana is leading Product at Prior Labs. She is a part of the team developing TabPFN, a foundational model for tasks on structured data. TabPFN was published in the 2025 issue of Nature journal, and has shown to beat classic ML methods like XGBoost in >80% of cases. Diana's former background is in machine learning, and she spent last years leading product at developer-focused startups in Berlin. **Lightning talks** There will be slots for 2-3 Lightning Talks (3-5 Minutes for each) between the two main talks. Kindly let us know if you would like to present something :) \*\*\* NumFOCUS **Code of Conduct** THE SHORT VERSION Be kind to others. Do not insult or put down others. Behave professionally.
