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. For our full event schedule, visit [https://shutupwrite.com](https://shutupwrite.com). **Other Important Details:** WiFi name/password: TBD Venue Guidelines: Please thank our hosts by purchasing something.

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. Please join our WhatsApp group: https://chat.whatsapp.com/JeAa2uRNTlF0rdrVTLzUC0?mode=wwt Note: there's always enough sitting room, but some of it is on the grass or a mat on the floor. If you want to guarantee yourself a chair, please bring one with you. Sapere Aude! (Kant's Motto: Dare to Think!)

Come join us at Nova Labs for our monthly lockpicking meeting! We meet every third Wednesday at the Nova Labs Fairfax location at 3850 Jermantown Road. Learn about locks, lockpicking, lock modifications, and even lock smithing in our classroom environment. No tools, skills, or knowledge required, but feel free to bring any of those things with you! Our meetings are overseen by one or more locksmiths.

**Agenda:** * 6-6:30 pm: Networking and food/drinks * 6:30-7:15 pm: Announcements and presentation * 7:15 pm-7:30 pm: Q&A and close-out **Hacking the Stack: Using OpenSearch Dashboards as an Application Framework** Most developers treat OpenSearch Dashboards (OSD) strictly as a visualization layer—a place for charts and graphs. They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of **an enterprise-grade risk, compliance, and security platform built entirely *on top of* OSD**. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience. Join us for a deep dive into the engineering reality of the OpenSearch stack, including: * **The Analysis:** Why the OpenSearch stack beat out the competition. * **The Build,** **Beyond Visualization:** How to implement custom React components to build complex workflows and interactive UIs within OSD. * **The Integrations:** Integrating Wazuh for agent management and ingesting data at scale. * **The “Gotchas”:** Honest, real-world lessons on data handling, state management, and what to look out for. **If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!**

Monthly meeting: Second Saturday of the month International House of Pancakes (IHOP) 775 Rockville Pike, Rockville, MD 20852 7:00 PM – 10 PM. Late arrivals always welcome.

Other things people would like to talk about. This will be a joint meeting with: DC 9/11 Truth [https://dc911truth.org/](https://dc911truth.org/) dc911truth Facebook page [https://www.facebook.com/groups/dc911truth/](https://www.facebook.com/groups/dc911truth/) 911 Meetup Group [https://www.meetup.com/meetup-group-kyegaoqu/](https://www.meetup.com/meetup-group-kyegaoqu/) Central Bank Digital Currencies CBDC Meetup Group [https://www.meetup.com/central-bank-digital-currencies-cbdc/](https://www.meetup.com/central-bank-digital-currencies-cbdc/) Freedom of Speech Meetup Group [https://www.meetup.com/silver-spring-freedom-of-speech-meetup-group/](https://www.meetup.com/silver-spring-freedom-of-speech-meetup-group/) One way to make it more difficult for them them to impose a digital currency on us is to use cash. Central Bank Digital Currency (CBDC) With Digital Currency they can: Have a complete government dossier on every detail of your life. Use your purchase history to maintain a detailed social credit score for every person. Provide tax breaks to corporations who hire people with admirable social credit scores. Only grant government contracts to corporations with employees with admirable social credit scores. Adjust health insurance premiums to incentivize people to develop admirable social credit scores. Connect your social credit score with a digital ID to encourage you to look at only approved web sites when surfing the internet. Viewing conspiracy web sites could lower your Social Credit Score and make it difficult to get a job. With their electronic chain around your neck, they can control where, when, how you travel, what food you are allowed to buy etc. They will love the power to only allow you to use your digital money only where they want you to shop and allow you to buy only what they prefer you to buy. Require you to have to have a license to use your money. They will call it a Digital Currency License. Require you to take any vaccine they want you to take to maintain your digital currency license. Tax you in ways we have not even imagined. Adjust your income tax rate based on your social credit score. Use AI to increase your income tax rate if you eat too many hamburgers because they will tell you eating too many hamburgers will increase global warming. This is just one example of many behaviors they might not approve of. Adjust individual prices for different individuals. They will be able to make you pay more per pound for hamburger if you purchased too much red meat during the past 30 days. Require you to buy so many pounds of soy burger for every pound of hamburger to save the planet and increase the profits for the soy burger manufacturers. Turn off the digital money of people they consider to be spreading misinformation. Turn off the digital money of people they consider to be dangerous conspiracy theorists. Turn off your money at 8 PM if they want a curfew at 8 PM Turn off your money in another state if they do not want you to drive to another state without permission. Turn off your money when buying guns or ammo if they do not want you to buy guns or ammo. Turn off your digital money more than three miles away from your home if they want you to stay within three miles of your home during the next epidemic. Etc. etc. etc. From the standpoint of the government, one beauty of digital money is that your money is one “state emergency” away from being the government’s money. All they have to do is to take your digital money out of your Central Bank Digital Account for the “good of all”. It is not as easy for them to do this with physical cash, gold, stocks, or silver etc. Anything they **can** do, they will do. The essence of slavery is control. Digital Currency will enable them to make you, their slave. (in a global digital concentration camp). .
