DataTalks x april: The Rise of Tabular ML
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 โ bringing foundation model thinking into structured data.
***
## The Talk ๐
**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 โ 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 learningโs potential for structured data.
***
## โโAbout the Speaker ๐จ๐ปโ๐ซ
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 โ the company behind TabPFN โ where he works at the frontier of structured data modeling.

Shut Up & Write!ยฎ at Beit Ariela
Join us for some focused writing time. All writers and all experience levels are welcome and donโt 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 youโre all settled, take some time to chat with your fellow writers. Once everyoneโs arrived, I will lead quick introductions and then set the timer for our quiet and focused writing session.
Afterward, weโll have time to chat and get to know each other. We often talk about our successes and challenges as writers. If you donโt have time to stick around, no worries!

**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 youโve seen in period films such as โPride and Prejudiceโ, where the dancers are lined up in long lines, across from each other. Thatโs English Country Dancing, the predecessor of contra dancing. Now, add moves like โswing your partnerโ and โdo-si-do,โ like youโve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alรก โRiverdance.โ 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. THATโs 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.

Pranic Healing Level I - PH I--- DAY 2 of 2
MCKS PRANIC HEALINGยฎ Level I
In PRANIC HEALINGยฎ Level 1, you learn the basics of working with your energy aura, including learning to "scan," or feel the energy, to "sweep," or clean away congested energy, and to "energize," or supplement areas in your aura that have a pranic deficiency.
PRANIC HEALINGยฎ has been taught to doctors, nurses, massage
therapists, acupuncturists, chiropractors, shiatsu practitioners, and many others in the healing field. It has allowed them to heal confidently and consistently in the shortest learning time possible. These professionals find PRANIC HEALINGยฎ very effective and easy to apply.
Other topics covered in PRANIC HEALINGยฎ Level 1:
Energetic anatomy: You will learn to work with the network of chakras, meridians and auras to accelerate the healing processes of your body.
Preventive healing: You will learn to remove the negative energetic patterns of a disease to prevent it from fully manifesting as a physical ailment.
Self-Pranic healing: You will learn to apply these healing techniques to accelerate your own healing.
Step-by-step techniques for ailments related to your:
respiratory system, e.g., asthma,; circulatory system, e.g., heart ailments; gastrointestinal system, e.g., irritable bowel syndrome; musculoskeletal system, e.g., arthritis and back pain; reproductive system, e.g., menstrual problems. You'll also learn how to address common problems as migraines and sinusitis.
Additionally, you'll learn to apply distant healing to loved ones who are not present in the room with you.
All PRANIC HEALINGยฎ courses are "experiential," which means that you learn by actually performing the techniques and exercises in class - on yourself and those around you. During class, all the principles will be explained thoroughly and you will practice the techniques exhaustively so you will be confident in your ability to produce positive results when you finish the course.
This is Day 2 of 2 Attendance at day one is required to attend day 2.
The Course text book is Choa Kok Sui, "Miracles through Pranic Healing" Please bring this with you to class.
PRANIC HEALINGยฎ Level 1 is a prerequisite to all other GMCKS courses.
For those interested to review the class...Review fee is only $75!!
LOOK AT THIS!! Review for FREE when you bring a new student to class with you.
Celebrate National Chip and Dip Day!
***Okay, call me crazy but you have got to try their chip n dip!*** Club 185 is a true hidden gem in German Village! Seriously, old school, good comfort food and drink. We will try to gather in spaces near the windows. While we'll share Chip n Dip, you'll want to order a sandwich, too.
**Where the Chip Began (1817)**
Potato chips can be traced back to an English chef, William Kitchiner, who includes โcrispsโ in his bestselling cookbook, โThe Cookโs Oracle.โ
**Chip and Dip Popularity**
The popularity of chip and dip skyrockets at the end of World War II with new entertainment fads and the introduction of Liptonโs new advertising campaign for their famous French Onion Dip. (Club 185 doesn't openly admit it, but I'm pretty sure that's their dip recipe!)
**[Club 185](http://club185.com/)**โa true neighborhood bar serving since 1954, when it was known as a local 'speak-easy'. Located in German Village, Club 185 features a menu of quality casual comfort food and full bar. From politicians to lawyers, hardhats to hipstersโall find Club 185 the perfect place to tame their hunger and quench their thirst!
**PARKING**: I know, brick street parallel parking can be a pain. Two other choices, metered parking along Livingston heading towards Children's Hospital or across the street in the large church lot (park in spaces farthest away from the church entrance doors, closer to the street).
**PRE-EVENT**: **HAPPY HOUR (3-5pm)**: Italian drinks and bites at [Cento's happy hour](https://centogermanvillage.com/menus/), nearby.
Let's try a Friday Night Fish Fry!
We thought of one of the interesting things that can be enjoyed at this time of the year. We will be meeting at Immaculate Conception Catholic Church for a "Fish Fry" in Marian Hall on Friday, March 27th at 5:00 PM.
It might be fun for you to experience what has become a tradition on the Fridays before Easter. They will have fried fish or baked fish, French fries and Cole slaw, as well as beverages, all for $16.00 for adults. They will have other beverages and desserts available for sale, as well. We have never tried this, and sometimes there are quite a few people at these events so we hope that we will be able to find each other easily. I'll try to have signs outside Marian Hall that Identify our group. We hope to have you join us!
