PyData Berlin 2026 August Meetup

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: From Discovery To Transaction: Personalizing Marketplaces with Intent-Aware Ranking** **Abstract**: In the world of online marketplaces, growth can be a double-edged sword: with a larger supply and user base, making the “perfect match” becomes harder to achieve. For GetYourGuide—a global online marketplace for travel experiences—this meant a single, static experience no longer worked equally well for a diverse global audience. To move past this “one-size-fits-all” limit, we shifted from treating users as one monolithic group to predicting intent in real time. By analyzing user behavior, we found two common planning modes. Discovery users are exploring what’s possible in a destination. Transaction users return with a clearer goal and are closer to booking. In this talk, we’ll explain how we built a segmentation framework and a production service that updates these segments in real time using machine learning. We’ll show how these user segments feed into our activity ranking models to personalize results and improve relevance across the search journey. We’ll close with measured impact on engagement and conversion, and what this approach can unlock for other marketplaces moving beyond static user experiences **Speaker**: Kaan Isik and Mihail Douhaniaris **Bio**: * Kaan Isik is a Senior 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. * Mihail Douhaniaris is a Senior Data Scientist at GetYourGuide, where he specializes in marketplace search & ranking algorithms to improve search relevance. His work helps travelers find experiences that match their preferences more effectively. Beyond his role, Mihail is interested in responsible AI, ML observability, and the challenges of deploying machine learning at scale. **Talk 2: Speeding up PyFixest's fixed effects demeaning with new algorithms and Rust** **Abstract**: Fixed effects regressions are ubiquitous in applied data science: they are employed for difference in difference models, switchback designs, variance reduction... Based on the structure of fixed effects, the standard approach to fit fixed effects models at scale can become very inefficient. Therefore, we have developed a new strategy that works extremely well when the default solver struggles. In the talk, I will introduce fixed effects modeling, how it is usually implemented computationally, explain intuitively when/why the default solution can be slow, and introduce our new strategy that is implemented in the rust crate "within" and can be called from Python and R and is already available via the pyfixest regression library. **Speaker**: Alexander Fischer **Bio**: During the day, Alexander works as a data science lead on auction and experimentation topics at trivago. During the night and weekend, he works on open source. Most of his time goes into a package for linear regression - pyfixest - for which, around 4 years ago, we had the stated goal to “make fixed effects regression in Python as nice as in R” before the agents would start writing all of the code. Looking back, we almost succeeded! =) **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.

Offener Deutschunterricht - Text & Konversation - Niveau B2+ (Fortgeschritten)
Tue, Aug 25, 5:00 PMIn 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. Falls Sie an der Bar etwas kaufen möchten, beachten Sie bitte, dass ausschließlich Barzahlung akzeptiert wird.
