**Join Us for PyData Meetup @ Melio!** Get ready for insightful sessions, networking with the PyData community, and, of course, pizza and beer! A big thanks to **Melio** for hosting us and supporting the community. **📅 Details** Date: Sunday, June 14th, 2026 Time: 18:00 - 21:00 Location: Melio Office, Hagag Towers, North Tower, Floor 32, HaArba’a St 28, Tel Aviv Language: This meetup will be held in Hebrew **🕒 Agenda** 18:00: Gathering, snacks, and drinks 🍕🍻 18:30: Welcome words 18:45: **A Match Made in Heaven: LLM Judgment at Vector-Search Speed,** Shon Mendelson, Staff AI Scientist @ Intuit 19:15: **Dr. Data: How We Learned to Stop Worrying and Love the AI Bomb**, Dr. Adi Sarid, CEO @ Sarid Research 19:45: **Cost-Efficient AI Systems in Practice,** Michael Levinger, Senior AI Engineer @ Melio **🎤 Featured Sessions** **A Match Made in Heaven: LLM Judgment at Vector-Search Speed** **Speaker: Shon Mendelson, Staff AI Scientist @ Intuit** Last year, I spent far too long chasing a stubborn data quirk: why our system couldn't see that “The Law Offices of John Miller” and “Miller, John S. PLLC” were the same entity. It led to a bigger question: can you achieve LLM-level judgment at vector-search speeds? Traditional vector search is fast, but often misses subtle context like this, while relying entirely on LLMs is too slow and costly for production at scale. In this talk, I’ll share how we bridged that gap at Intuit with a hybrid system that combines fast vector search, efficient small transformer-based models, and fine-tuned SLMs. The result is a system capable of handling millions of weekly entity comparisons, significantly boosting recall while maintaining precision levels comparable to traditional methods. **Dr. Data: How We Learned to Stop Worrying and Love the AI Bomb** **Speaker: Dr. Adi Sarid, CEO @ Sarid Research** When GenAI dropped, our quant market research agency had a beautifully naive thought: "We can finally replace all our human labelers with a simple API call!" Spoiler alert: Scaling AI without hallucinations isn't quite that simple. Join us for a brutally honest, technical look at our data science team's journey from prompt-panic to AI-powered productivity. We’ll share our biggest wins and hardest lessons regarding evaluation frameworks, the rapid obsolescence of custom packages, and the newfound "full-stack audacity" of modern data scientists. **Cost-Efficient AI Systems in Practice** **Speaker: Michael Levinger, Senior AI Engineer @ Melio** Deploying large language models and AI agents in real-world systems requires a constant trade-off between cost, latency, and performance. This talk explores how to optimize LLM- and agent-based systems using techniques such as caching, model routing/cascades, tuning, RAG, and distillation—significantly reducing costs without sacrificing quality. Through a case study of an ATO-agent system, we’ll also cover practical approaches to cost estimation, monitoring, and budgeting. In addition, we’ll compare leading industry models—such as Gemini, Claude, and GPT—focusing on differences in response speed, cost efficiency, and real-world performance, and how to choose the right model for each use case within broader agentic workflows. **🚀 RSVP** Space is limited – RSVP now to secure your spot!

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Can Artificial Intelligence ‘See’?”** A look at how humans and artificial intelligence systems interpret the visual world in fundamentally different ways, with Arryn Robbins, assistant professor of psychology at the University of Richmond and cognitive scientist who researches visual attention, perception, and category learning. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-can-AI-see](https://events.ticketleap.com/tickets/profsandpints/nv-can-AI-see) .] Artificial intelligence can now identify faces, categorize objects, describe scenes, and outperform humans on certain visual tasks. But does AI actually “see” the world the way that people do? Or does it arrive at correct answers using representations that differ markedly from human perception? Join Arryn Robbins of the University of Richmond for a fascinating exploration of how humans and AI construct meaning from visual information and a look at comparisons between human perception and AI that reveal just how dynamic and context-dependent our own visual systems really are. Dr. Robbins, who previously has given excellent Profs and Pints talks on flaws and biases in human visual perception, will draw from research in cognitive science, visual perception, and AI vision systems. She’ll explain how human perception is not merely a simple recording of the world, but an active process shaped by expectations, context, goals, and recent experience. You’ll learn how humans form flexible mental representations that allow us to recognize objects across changing environments and conditions, and why those representations continuously adapt as we interact with the world. Many AI systems, by contrast, learn visual categories through statistical patterns in data. They can produce impressive results, but sometimes they also produce strange and unexpected failures, and sometimes they classify images in ways that seem strange to us. Dr. Robbins will discuss what these differences reveal about the nature of perception itself, and why the mismatch between human and AI representations matters for technologies like self-driving cars, medical imaging, facial recognition, and automated surveillance. Important for anyone trying to understand the rapidly growing role of AI in daily life, this talk will explore one of the biggest questions in cognitive science and artificial intelligence: What does it actually mean to “see” and understand the world?

How strong are you—really? Most of us underestimate our own resilience, courage, and capacity to overcome challenges. Yet within each of us is a wellspring of strength waiting to be expressed. Join us this Sunday at **Unity of Fairfax** as we explore the spiritual faculty of **Strength**—one of the divine qualities that empowers us to move forward with confidence, perseverance, and purpose. Through a Unity perspective, we'll discover how strength is more than physical power or willpower. It's an inner resource that helps us face uncertainty, navigate change, and live more fully as our authentic selves. Whether you're facing a challenge, seeking encouragement, or simply looking to grow spiritually, you'll leave inspired to recognize the strength that already lives within you.

We will be hiking the loop trail, (counter clockwise) around the BeaverDam Reservoir starting at the brand new Reservoir Park VisitorsCenter. Beautiful views of the water and varied woodland areas. This is an 7.5 MILE loop hike around one of Northern Virginia's largest bodies of water. The loop is mainly flat with a tiny hill or two. I've rated the loop moderate because the distance is 7.5 miles and we will be hiking about 22 minutes per mile - just under 3 miles per hour. After the hike we'll head over to Lark Brewing. 24205 James Monroe Hwy, Aldie, VA 20105 for food and beverages. I will make every effort for your safety. You are hiking at your own risk. Dogs are welcome on the hike as long as they are good with groups, friendly and you follow all leash laws. I like kids but this is an adult event so please no kids or any one under 21. We do start on time so please plan accordingly. Meet in front of the bathrooms by the parking lot.
