Our next **DataTalks TLV meetup** will explore one of the most exciting emerging directions in machine learning: **Tabular Foundation Models**. For decades, structured data problems have been dominated by tree-based models like XGBoost and Random Forest. While deep learning transformed NLP and vision, it consistently struggled to outperform classical methods in tabular settings. Over the past year, a new paradigm has begun reshaping the field — bringing foundation model thinking into structured data. *** ## The Talk 🌐 **From Trees to Transformers: The Rise of Tabular Foundation Models** Speaker: Alan Arazi In this session, Alan will: * Provide a clear overview of the tabular learning landscape * Explain why deep learning historically underperformed on tabular tasks * Introduce TabPFN — a breakthrough model trained to perform Bayesian inference over tabular datasets * Dive into how it is trained, how it works, and what makes it fundamentally different * Discuss what this shift means for the future of data science This talk is designed for ML practitioners, researchers, and data professionals who want to understand what comes after gradient boosting and how foundation models may finally unlock deep learning’s potential for structured data. *** ## ‍‍About the Speaker 👨🏻‍🏫 Alan Arazi is a PhD candidate at the Technion under Prof. Roi Reichart, researching Tabular Foundation Models. After five years working with large language models at AI21, he joined Prior Labs — the company behind TabPFN — where he works at the frontier of structured data modeling. *** ## Location📍 * April Offices * 7 Totseret HaAretz St., Tel Aviv-Yafo * Networking and Q&A included. We hope to see you there!

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer. Thanks to our 2026 sponsors: [Clarivoy](https://www.clarivoy.com), [What Box Consulting Group](https://www.whatboxconsultinggroup.com), [Conductrics](https://www.conductrics.com), and [Piwik PRO](https://piwik.pro) More info at [cbusdaw.com](https://cbusdaw.com)
