Big Data

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)

**ProductTank NoVA is back!** After a brief hiatus, we are relaunching the chapter with a format that cuts out the fluff and gets straight to the reality of building. Every product feed is flooded with AI hype right now, but what does it actually look like on the ground? Instead of a polished keynote, we are hosting **0 to 1 with AI: Real Product Talks**—a "Show & Tell" featuring 3–4 lightning talks focused on the intersection of AI and product. The framing for the talks is simple: *"Here is what I'm building, and here is what I'm stuck on."* We want to look at the messy, 0-to-1 reality of integrating AI into your workflows and products. *(Want to share what you are working on? Reach out! The bar is low-pressure, just 10–12 minutes to talk about a real AI problem you are trying to solve.)* **Agenda:** * **5:30 PM - 6:00 PM:** Doors open, networking, & name tags * **6:00 PM - 6:10 PM:** Welcome + Chapter Relaunch Intro * **6:10 PM - 7:30 PM:** Lightning Talks (Three 12-min talks + 5 mins Q&A each, with a 5-min stretch break) * **7:30 PM - 8:00 PM:** Open networking * **8:00 PM:** Soft close **Location & Logistics:** Herndon Fortnightly Library (Extended Hours Meeting Room) 768 Center St, Herndon, VA 20170 * **Parking:** We'll meet at the library, located just behind the Herndon Municipal Center. There is plenty of free public parking available around the municipal center. * **Metro & Bus:** Take the Silver Line to Herndon Metro Station, then connect via Fairfax Connector Route 921 or 950 to Historic Downtown Herndon. * **Driving (via VA-267/Dulles Toll Rd):** Take Exit 10 North (Centreville Rd, which becomes Elden St). Turn left onto Station St or Lynn St. * **Driving (via VA-286/Fairfax Co Pkwy):** Take the Elden St West exit. Turn right onto Lynn St. Looking forward to seeing everyone again and getting back to building!

Most AI meetups end up as just networking. **We’re different.** At **AI Tool Explorers Night \| Connect & Make New Friends**, you’ll: ✨ Walk away with a *real learning nugget* (a tool, workflow, or strategy you can use immediately) ✨ Connect with people who share your curiosity for AI, productivity, and automation ✨ Enjoy a fun, casual setting where new ideas and friendships spark naturally 👉 **Our promise:** every session delivers structure, substance, and takeaways you can use when you get home. ### 📅 Event Flow * **6:00–6:15 PM** → Arrivals & intros * **6:15–6:45 PM** → AI demo / learning nugget * **6:45–7:00 PM** → Q&A and group discussion * **7:00–8:00 PM** → Networking & contact sharing ⚡ Please hold networking until after the presentation so we can all learn together. Plenty of time at the end to connect and exchange cards! **Let's explore AI Tools that actually *work* in our day-to-day life!** *** #ChatGPT #Claude #Grok #Gemini #Perplexity #DeepSeek #NotebookLM #Cursor #GitHubCopilot #Replit #Windsurf #v0dev #Lovable #Zapier #Makecom #n8n #Descript #OpusClip #Synthesia #Runway #Sora #Kling #Veo #PikaLabs #LTXStudio #AdobeFirefly #Vidu #Hailuo #LumaDreamMachine #Wisecut #Elaiio #Capsule #Filmora #Gling #Magisto #AdobePremierePro #ElevenLabs #Suno #Udio #Soundraw #Riffusion #Mubert #BeatovenAI #AIVA #Loudly #SplashPro #Soundful #MagentaStudio #WavTool #MakeBestMusic #BandLabSongStarter #TadAI #EcrettMusic #Midjourney #DALLE3 #CanvaMagicStudio #NotionAI #Gamma #Fathom #FirefliesAI #MLX

**REGISTER AT THE LUMA EVENT PAGE!!!** https://luma.com/27ja5gwl Join us for an exciting talk by Mary Gibbs, Senior Applied Scientist at Relativity. ​ ​**​Agenda:** ​​6:00 - 6:30 PM - Welcome and mingle 6:30- 6:45 PM - Introductions 6:45 - 7:30 PM - Talk 7:30 - 8:00 PM - Wrap up **​​Description:** ​If you have ever shipped a model, watched your metrics improve, and later learned from your users that something was wrong, the metrics were always wrong. You just didn’t know it yet. An evaluation consists of three components, a benchmark, a scorer, and a claim about what a score represents. Each component has its own weaknesses. Benchmarks can suffer from narrow coverage, contamination, or saturation. Scorers are often chosen for ease of automation or computation rather than for their alignment with user outcomes. And the claim connecting a score to reality is rarely made explicit. These gaps compound across the model development lifecycle. When metrics improve, teams treat that as a signal and optimize directly against it, which is how a measurement problem becomes a model problem. This talk maps where evaluations can go wrong, considers counterarguments, and ends with practical advice for building better ones. **​Speaker Bio:** ​Mary is a Senior Applied Scientist at Relativity, tackling data science challenges in the e-discovery and legal tech space. She is also an organizer for Women and Gender eXpansive Coders DC (formerly Women Who Code DC), fostering a community dedicated to empowering women and nonbinary individuals to excel in their careers. Mary's experience spans various domains. She has developed data science solutions related to job search and career progression at Teal, cybersecurity challenges at LiveAction Software, and commercial and government consulting at Mosaic Data Science. Before venturing into the field of data science, Mary conducted and published research pertaining to the cellular and molecular mechanisms underlying neurodevelopment at the National Institutes of Health. In other words, she has dissected and imaged a lot of fruit fly brains. She holds a M.S. in Data Science from The George Washington University and a B.A. in Biological Sciences from Cornell University

**Saturday • May 16 • 2–5 PM • Ashburn, VA** Many people say they want to write a book someday — **this session helps you start.** Your life experiences already contain stories, lessons, and insights that could become books. The real challenge is **how to organize those experiences and actually turn them into writing.** In this interactive session, I’ll share the approach I’m using to build a **multi-book journey based on lived experience.** So far I have: 📚 **3 books published on Amazon** 📖 **1 more books releasing this year** (end of the year) 📝 **16 additional books planned** — and likely many more. This session is not about writing **just one book**. We’ll explore how your experiences can evolve into **multiple books over time**, and how to **use AI the right way to speed up your writing while keeping your voice authentic.** *** ### What We’ll Explore • Turning life experience into book ideas • How one journey can become multiple books • Simple ways to structure stories and lessons • Using **AI to organize ideas and speed up writing** • Practical strategies to actually finish a book **Everyone will leave with the outline of their first book idea.** **You don’t need writing experience — just curiosity about how your life experiences might turn into ideas worth sharing.** *** ### Event Details 💵 **$25 RSVP — includes coffee + snacks** 📍 **Ashburn, VA** (exact address shared after RSVP) 🕑 **2:00 PM – 5:00 PM** 👥 **Max 10 people** for a small, interactive conversation. Most attendees are professionals, entrepreneurs, and people navigating reinvention or new chapters in life. *** # Background — Writing & Reinvention Journey Writing has been one of the most powerful tools in my own reinvention journey. What began as reflections during a difficult life transition gradually evolved into published books and a growing body of work focused on reinvention, personal growth, and life transitions. My goal is not just to write books — but to help others realize that their experiences may also hold stories worth sharing. *** # 🔗 Midlife Reinvention Ecosystem 🌐 Website [https://midlifereinvention.co](https://midlifereinvention.co) ▶ YouTube (400K+ views) [https://www.youtube.com/@midlife_mindfulness](https://www.youtube.com/@midlife_mindfulness) 💼 LinkedIn (4K+ followers) [https://www.linkedin.com/in/anju-debnath-0061524/](https://www.linkedin.com/in/anju-debnath-0061524/) 🤝 Meetup Community (300+ Members) [https://www.meetup.com/ashburn-transition-meetup-group/](https://www.meetup.com/ashburn-transition-meetup-group/) 📚 Amazon Author Page [https://www.amazon.com/stores/Anju-Debnath/author/B0FFNBVZLQ](https://www.amazon.com/stores/Anju-Debnath/author/B0FFNBVZLQ)
