Kommt am 2. Montagabend im Monat ins Offene Wohnzimmer zum Open Draw! Raucht Euch auch manchmal der Kopf von zu viel PC-Arbeit? Der Asphalt der Stadt ist heute wieder viel zu grau?

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.

# **Band: Old Possum's Menagerie; Caller: Richard Ades** Beginner lesson at 1:30, regular dancing begins at 2:00 pm NOTE THAT WE ARE TEMPORARILY DANCING IN THE AFTERNOON INSTEAD OF EVENING. Dance with us in the afternoon then you can still go out in the evening! **Sponsor: All Soles Contra and Square Dancing, First Unitarian Universalist Church, 93 W. Weisheimer Rd., Columbus OH 43214** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 1:30 - 2:00, followed by dancing 2:00 - 430. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. Please bring your own refillable water bottle.

Thursdays just got smarter (and sassier). 🧠🍻 Join us at TownHall Short North for Trivia Night with Marquis—where the questions are fun, the competition is friendly, and the vibes are immaculate. Grab your crew, sip something good, and prove you know random facts you absolutely shouldn’t.

Join us at **Unity of Columbus** for *Spa for Your Soul*, a restorative and inspiring workshop designed to nourish your spirit, awaken your inner wisdom, and reconnect you with the sacred rhythm of life. Drawing from the rich spiritual insights of **Matthew Fox** and the timeless theological wisdom of **Thomas Aquinas**, this workshop invites participants into a deeper experience of spirituality rooted in compassion, creativity, and divine presence. Together, we will explore spirituality not as something distant or abstract, but as a lived, embodied experience—one that honors joy, justice, beauty, and the inherent goodness of creation. Through guided reflection, gentle spiritual practices, discussion, and contemplative moments, *Spa for Your Soul* offers a sacred space to release stress, renew clarity, and remember the divine spark within. This is an opportunity to pause, breathe, and tend lovingly to your soul—much like a spa experience, but for your inner life. Whether you are seeking spiritual refreshment, deeper understanding, or simply a peaceful space to be present, this workshop welcomes you exactly as you are. **Come, rest, reflect, and renew—your soul deserves it.**

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics. His work focuses on helping organizations like the Ohio Supreme Court design, analyze, and communicate compensation systems that are data-informed, defensible, and aligned with organizational goals. Alex lives in Granville, Ohio and has three little kiddos. More info at [cbusdaw.com](https://cbusdaw.com)
