Tolle Berlinerinnen und Berliner, als ich schreibe, sitze ich im Wald zwischen Buchen und Eichen auf meinem Campingstuhl und genieße die Ruhe des Sonnenlichts. Suchst du nach Freiheit von dem Lärm der Szene, Lärm der Stadt? Möchtest du Brücken mit interkulturellen, diversen Leuten aufbauen? Dieses Jahr möchte ich unbedingt neue Leute, die Tiefe und Empathie haben kennenlernen. Diesen Leuten meine Zeit geben, und gegenseitige Freundschaften hoffentlich aufbauen. Selbst glaube ich, dass Mädels und Jungs einander nicht verstehen können, wenn der Sinn von einer Person 100% einer Geschlecht ist und die Person keines der Geschlecht gegenüber kennt. Idealerweise sollte der Sinn 50/50 weiblich/männlich sein, dass wir uns gegenseitig ideal verstehen können. Selbst bin ich Künstler, der sich für Farbphysik (Colour Phenomena) interessiert. Zum Beispiel ein roses Kirschbaum in der blauen morgen Stunde. Oder blaue Bäume im Licht eines bedeckten Sommer Tag, auch wenn jeder glaubt, dass man sachlich weiß, ‚Bäumen sind grün!‘ Colour sind, glaube ich, hauptsächlich weibliche Phänomene. Und als Künstler empfand ich seit langem eine Affinität für Colour. Das Bild oben ist ein Kunstwerk von mir. Ich möchte die ruhigen Leuten erreichen, also der Treff ist entweder Online, per Signal Messenger (Link zur Gruppe im Kommentar; nur für Teilnehmer der Veranstaltung sichtbar) um neue Verbindungen leicht zu machen, oder auch sogar besser persönlich, wenn du dich spontan unterwegs sein will und persönlich treffen will. Wenn du mich persönlich triffst setzen wir uns auf eine Wiese, eventuell in der Wuhlheide, oder auf dem Tempelhofer Feld. Schick mir eine Nachricht vorher per Signal Gruppe und wir können uns vereinbaren. Dieses merken: Bitte rauchen Sie bei dieser Veranstaltung nicht. Ich freue mich neue Leute kennenzulernen! Mit geschmackvollen Grüßen, Duncan

**After Work Pilgrims: Walk with intention.** Berlin is demanding, and the day was long. And somewhere between finishing work and the night, there's a moment where we just need to breathe. That's what After Work Pilgrims is for. We walk together through the city – through parks in the middle of all the concrete – with intention. Just a few kilometres on foot: with silence, a short reflection, and good company. It's more than a walk. But it doesn't feel like it. Duration: approx\. 2 hours \| Distance: 4–7 km \| Free No experience needed. Comfortable shoes recommended. Come as you are. *** 📅 Wed, May 27, 6:00 PM 📍 Mauerpark & Humboldthain (Meeting point: at Gedenkstätte Bernauer Straße, [https://maps.app.goo.gl/mfuaiQRrPDFjtMpBA](https://maps.app.goo.gl/mfuaiQRrPDFjtMpBA)) 📩 You’re welcome to join our [WhatsApp group](https://www.alexander-steinfeldt.de/hikes/berlin-pilgrims/) for updates and connection before the hike. 🧭 Pilgrim Guide Alex (Mail alexander.steinfeldt@outlook.com or WhatsApp +49 157 57652601)

"No half-thruths, just naked minds” Welcome to the comedy show where you can see unfiltered comedians speak their thruth since almolst 5 years! Their topics can range from their last sexual encounter to why they hate chickens and how to win a fight with a chesse sandwich. So expect any kind of material from clean to the very dark. Each comedian will have between 5-10 minutes to make you laugh. The show is located in the cozy Agata Bar on Weichselstraße 55 in Neukölln - open for all of those who appreciate cozy nights and a fine selection of drinks and good mood. The space is limited, so the early bird catches the worm - get a reservation for your own good! Doors: 19:30 Show: 20:00 Get your free reservation now & pay what you want for the show! *Reservations are only kept until 20:15, so please arrive before that for assured seating.

You must complete the registration process on lu.ma to receive the full event location details and confirmation of your attendance. **Please note: Without approved registration on Luma, you will NOT be able to access the event location or attend.** We are excited to host a **BLISS x dida workshop** featuring **Lazar Obradović (Lead Data Scientist @ cognee.ai)**, who will guide us through an interactive session on Agentic AI. ​Title: Explainable Scientific Discovery with AI Memory: Hypothesis Generation and Validation with Cognee and Bayer 📅 Date: 27.05.2026 🕕 Time: 18:00 📍 Location: TU Berlin Marchstrasse 23 [Room 0.011] ​The session will last around 2 hours, followed by a networking session with dida and fellow AI enthusiasts (and free pizza!🍕). Bring your laptop! **​Abstract: Building "AI scientist"** systems that can reliably generate and evaluate research ideas remains effectively an open problem. While LLMs make hypothesis generation cheap, current systems still struggle to connect evidence across papers, domains, and mechanisms in a structured and reusable way. Evaluation is equally difficult, often relying on opaque “LLM-as-a-judge” methods that are hard to interpret or reproduce. We use Cognee to ingest scientific literature and construct a graph-based representation of papers, claims, and entities with associated vector embeddings. We then use this structure to select and organize the context used for hypothesis generation. Candidate hypotheses are evaluated using explicit graph- and vector-based metrics grounded in the underlying corpus. Initial evaluations by Bayer across targeted biomedical domains demonstrated that graph-based AI memory can reliably support scientific hypothesis generation and validation. **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend. The event location will only be visible after your registration is confirmed by the host.

Welcome to the PyData Berlin May 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: Text2SQL in the Wild — Agentic Workflows & Semantic Models on Customer Data** **Abstract**: Translating a business user's natural language question into a reliable SQL query has huge value for business analysts, but doing it accurately at scale, on messy enterprise data, for complex queries, is incredibly difficult. This talk walks through a production Text2SQL system built on four pillars: semantic models built on customer data, RAG-based semantic search, an agentic verification and correction loop for building the SQL, and an evaluation framework for the entire process. Raw schema information is not enough for text2sql to work. Rather, thorough documentation including business metrics, synonyms, and qualified example queries, are required. We'll cover how to automate this documentation pipeline by mining query logs, generating descriptions with LLMs, and organizing everything into a knowledge graph and vector search index. From there, we'll dive into the agentic flow that takes a user question and iteratively generates, validates, and fixes SQL against a live database. The agentic framework analyses syntax errors and execution results to help it fix the SQL. Participants will leave with practical takeaways on RAG architecture for structured data, agentic retry patterns, and how to think about evaluation for Text2SQL systems in production. **Speaker**: Oren Matar **Bio**: Oren Matar is a principal data scientist and algorithms developer, with a background in social sciences and Bayesian methods. He specializes in NLP and time series forecasting, as well as agentic methods for data retrieval and processing. **Talk 2: Interpreting and Communicating Statistical Models** **Abstract**: Extracting actionable insights from complex statistical models remains a challenge, as raw coefficients are often uninterpretable due to nonlinearity, interactions, or hierarchical structures. This talk introduces a unified framework for model interpretation based on the principles of the Marginal Effects project ([https://marginaleffects.com/](https://marginaleffects.com/)). We move away from internal model parameters toward quantities of interest, such as marginal effects and adjusted predictions that translate statistical output into the "natural language" of the data. We will demonstrate these concepts in Python using the Bambi interpret module, showcasing a seamless workflow for interpreting Bayesian models built on PyMC. The audience will learn how to use the four primary interpretative pillars: Predictions, Comparisons, Slopes, and Marginal Means to compute average marginal effects and visualize conditional relationships. By the end of this session, you will be equipped to turn sophisticated GLMs and multi-level models into clear, rigorous narratives that are easily communicated to stakeholders. **Speaker**: Juan Orduz **Bio**: Juan is a Mathematician (Ph.D. Humboldt Universität zu Berlin) and Principal Data Scientist at PyMC Labs. He is interested in interdisciplinary applications of mathematical methods. In particular, time series analysis, Bayesian methods, and causal inference. **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.

The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|
