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.

Freestyle vocal workout at and play session. €8-20 😌 Flow is a state of being… an experience when you allow yourself to be 100% fully engaged in the present moment in a feedback loop between clarity and satisfaction. It is an undeniable sensation where things seem to be more effortless, pleasurable, in sync, and you can easily sense a connection with something greater than yourself; this is what we will create…: • a connected and mindful meditation where it is possible to blissfully surf the cutting edge of the present moment together… • a game where it’s possible to feel excited and calm in the same moment, and everyone can win as much as they like… Scott Bolden, founder of Das Baumhaus Berlin will share some very easy, practical and effective methods developed during the last 12 years of facilitating the “Improvisational Groove Orchestra” (I.G.O.) improv vocal jam sessions. Within 20 minutes participants learn to use the common sound space to create resonance in the form of improvisational music where it is quite common to experience some real flow moments… It is very easy to participate, no musical talent or training is required so anyone is welcome to join. All of the session is done with eyes closed to avoid visual distractions and keep focus on the co-created sound space. During these sessions we will also have short breaks for feedback and refreshment. Important – Please be on time. It is very important to understand the methodology and warm up in the group before joining in! 🎤 @21:00 - Freestyle vocal workshop and practice session. €8-15 Have you ever wanted to learn how to do freestyle vocalizations?

This time we meet in the Monbijou park. 💡 How it works The event is split into two parts: 1. **Communication (10 minute rounds)** – One participant answers a round of design and behavioral questions. Each other participant gets to ask him one question. 2. **Feedback Round** – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged. 💡You will be asked: * **Light design problems** (high-level reasoning, not code) * **Behavioral questions** (“Tell me about yourself”, “Describe a challenge you faced...”) No need to prepare anything in advance — just bring curiosity and an open mind. 💡Note: location is the entrance to Monbijou park

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.

English is below In kurz & authentisch & unseriöser Künstler:) inneres und dann äußeres Fotoauge trainieren und Spaß dran haben. Wahrnehmung, Fotografie, Streetfood, Walk & beste U-Bahn :) Dazwischen Berlin in urban, lebendig, divers, dreckig, wunderschön, direkt im Kiezleben, mind. 1 Späti-Getränk, viele Reize und immer wieder ein Fokus. Dein Fokus. Wirst ihn immer wieder neu, anders, vertiefend für dich kennen lernen. Zwischen Ostkreuz bis Markthalle 9 wird unser Spielplatz sein. Ich freu mich darauf :) ausführlich, seriös: Dieser Street Walk verbindet urbane Erfahrung, Wahrnehmung und Fotografie in Berlin. Wir bewegen uns bewusst abseits klassischer Touristenrouten durch Friedrichshain, Kreuzberg und die Übergänge dazwischen. Straßenleben, Menschen, Bewegung und Streetfood gehören dabei genauso dazu wie das Fotografieren selbst. Dieses Format versteht sich weniger als klassische Fototour und mehr als urbane Erfahrung zwischen Wahrnehmung, Stadtgefühl und Fotografie. Die Kamera dient dabei nicht nur zum Festhalten von Motiven, sondern als Werkzeug, um bewusster zu sehen und Momente anders wahrzunehmen. Wer Lust hat auf schnelle Touristenbilder oder reine Technikvermittlung, wird hier wahrscheinlich nicht ganz glücklich. Wer dagegen neugierig darauf ist, wie stark Wahrnehmung, Aufmerksamkeit und Atmosphäre beeinflussen, welche Bilder entstehen und welche Erinnerungen bleiben, dürfte hier genau richtig sein. Das Format richtet sich an fotointeressierte Menschen, an Menschen ausm Kiez genauso wie auch Touris, die Berlin mal anders erleben wollen. Nicht als klassische Tour, sondern näher dran. Manche kommen fürs Fotoauge, manche für die Atmosphäre, manche einfach, um die Stadt (wieder) bewusster wahrzunehmen. Ich komme aus der Wahrnehmungspsychologie mit meiner Leidenschaft für Fotografie und verbinde diesen Blick mit urbanem Erleben. Und klar, auch der Gang zum Späti darf dabei nicht fehlen. Die ersten Walks sind Teil einer Beta Phase, in der ich gemeinsame Street Experiences auch ausserhalb von Teamevents ausprobieren möchte. Damit dieses Format in dieser Form möglich bleibt und sich entwickeln kann, liegt die Spendenempfehlung ab 20€. Bring Neugier, Kamera und/oder Smartphone für deine Wahrnehmung mit. Der Rest passiert unterwegs. Ich freue mich auf euch und auf die ersten gemeinsamen Walks diesen Sommer. This street walk combines urban exploration, perception and photography in Berlin. We make a conscious effort to stay away from the usual tourist routes, exploring Friedrichshain, Kreuzberg and the areas in between. Street life, people, movement and street food are just as much a part of the experience as the photography itself. This format is less of a traditional photography tour and more of an urban experience that blends perception, a sense of the city and photography. The camera serves not only to capture subjects, but as a tool to see more consciously and perceive moments differently. Those looking for quick tourist snaps or purely technical instruction are unlikely to be entirely satisfied here. On the other hand, anyone curious about how strongly perception, attention and atmosphere influence which images are created and which memories remain is likely to be in exactly the right place here. The format is aimed at people interested in photography, at Berliners from the neighbourhood as well as those who want to experience Berlin in a different way. Not as a traditional tour, but something more intimate. Some come for the photographic eye, some for the atmosphere, and some simply to perceive the city more consciously again. I come from a background in perceptual psychology with a passion for photography, and I combine this perspective with urban experiences. The first walks are part of a beta phase, during which I’d like to try out shared street experiences outside of team events as well. To ensure this format can continue in its current form, the suggested donation is from €20. Bring along your curiosity, a camera or a smartphone to capture your experiences. The rest will happen as we go. I look forward to seeing you all and to our first walks together this summer. Pierre

NOTICE CHANGE OF LOCATION. WE WILL BE MEETING AT THE SHARON WOODS METRO PARK - THIS MONTH ONLY. Sharon Woods Metro Park, 6911 Cleveland Ave, Westerville, OH 43081 Enter the park from Cleveland Avenue and stay on the main park drive until it dead-ends into a turn around parking lot. We will meet at the Schrock Lake Shelter just off this parking area to the right. We will be taking a Guided Walk with access very near the shelter, on the Edward S Thomas trail, an ADA flat, hard-packed gravel surface trail. This walk will be led by Carrie Keller, Outdoor Naturalist at the park, and Megan Richley, Inclusion Coordinator for the Metro Parks. Wear sneakers or other shoes covering the entire foot. Sandals or flip-flops are ill advised. Sighted guides will be available. Target audience for this group is persons who are visually impaired, especially those who have experienced recent loss, however, all are welcome, including family members and supports. Light refreshments will be served. There will not be a Conference Call option for this meeting.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Ranked the #1 Ice Cream Shop in Columbus in 2024, this is the perfect place to kick off our Summer of Ice Cream and grab a sweet treat after the show! Their menu features an array of traditional, specialty and vegan shakes, hot cocoa, and more! You can check out their full menu here: [https://www.shakeno8.com/menu.php](https://www.shakeno8.com/menu.php) PLAN: We’ll plan for a 7pm-ish showing and will meet in the lobby area about 20 minutes before the show. Once showtime is announced, advance ticket purchase is advised! Once you have yours, please list your seat number in the Comments section of this event. We'll head to nearby Shake No. 8 immediately following the show! Should be a fun one, Dan
