Join us in the search for the true, the good and the beautiful. Each meet is in one of two formats: a shared reading and open discussion of philosophical texts, or a continuing series of lectures based on the reading of a fascinating book of philosophy. Both formats are in Hebrew, with some reading of English texts, assisted whenever needed. We meet weekly Friday on 80 Rokach Boulevard, Tel Aviv, at the gardens of the Council for a Beautiful Israel. Welcome anyone interested in understanding life more deeply, regardless of age or prior knowledge. The love of wisdom is enough.

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!

Join us for some focused writing time. All writers and all experience levels are welcome and don’t worry, no one will see what you've written. This session is about getting your writing done and meeting other writers in your area. When you show up, say hello to everyone, grab a drink, and get your writing tools ready. Once you’re all settled, take some time to chat with your fellow writers. Once everyone’s arrived, I will lead quick introductions and then set the timer for our quiet and focused writing session. Afterward, we’ll have time to chat and get to know each other. We often talk about our successes and challenges as writers. If you don’t have time to stick around, no worries! **A note about the format** We don’t host critiques or readings. These events are a safe space for writers of all skill levels and genres to work on their craft, so no one will read or critique your writing.

**\*\*\* We've Moved! Bold Penguin - 6555 Longshore St, Dublin, OH 43017 \*\*\*** Jonathan Stevens **Polymorphic Association - The Good, the Bad and the Ugly** When Active Record works, it’s great. Polymorphic associations in Active Record promise elegant flexibility: one interface, many possible models. When they work, they feel almost magical. But when your application grows and real‑world complexity sets in, that magic can quickly turn into confusion, broken queries, and performance headaches. We’ll explore where polymorphic associations shine, where they silently introduce technical debt, and why even experienced Rails developers can end up wrestling with unscoped queries, tricky joins, and hard‑to‑optimize relationships. We’ll walk through real examples of tangled polymorphic logic—and more importantly, show practical strategies to refactor, untangle, or even avoid these pitfalls entirely. By the end, you’ll know when to reach for polymorphism, when to run away from it, and what to do when your complex query simply refuses to cooperate. **AGENDA:** * See updates to parking below * Doors open at 5:30, feel free to come and hang out before! * Official start of the meeting is at 6:30pm * After the meeting is done, we will go hang out at a nearby space in Bridge Park!
