Join the Columbus AI community for our quarterly gathering — a casual, community-focused evening where everyone has a chance to share, learn, and connect. These open mic–style events give anyone in the community up to **5 minutes** to present a project, share a tool, pose a question, or offer a perspective on the evolving AI space. No slides required — just a welcoming space to exchange ideas and keep the local AI conversation moving. If you’d like to take the stage, message \*\*Chris (the organizer)\*\*with a **title and short description** of what you’d like to share. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

Come assist Van Buren Shelter (https://ymcacolumbus.org/locations/vanburen) staff in serving dinners and cleaning up on the 3rd Tuesday of each month. Dinner for the women is 5-6 pm and for the families is 6:15-7:15 pm. There is ample free parking available in the shelter's lot. The recommended area to park is in green in the image above. There will be a new entrance for the time being. We are asking all volunteers to enter through the Donation Dock door, the orange mark on the image above. This door is located between the Single Adults and Family Shelter. You will see 2 large garage doors with a large green trash compactor in the center. Please head to the closest garage door to the building wall, with a ramp leading up. There, you will see a door with a sign stating instructions on how to enter the building. Please ring the doorbell, and a staff member will come and escort you into the building. If a staff member takes longer than 5 minutes, please call the front desk at 614-689-2020. This is a new process for us, and we do not want to keep you waiting! We appreciate your patience as we navigate this temporary change. The shelter needs a volunteer count the day before the event so sign-up ends Monday at 4:50 PM. Afterwards some of us go to the Omnipresent Atheists Weekly Meetup in progress to have a bit to eat or drink (http://www.meetup.com/omnipresentatheists/). Volunteers must be 14 or older. Since we will be working around families, the YMCA does not permit volunteering by individuals with convictions for violent or sexual crimes. The YMCA reserves the right to run background checks on volunteers. For questions, comment on this page or contact: Andrew, awhit12@yahoo.com, (614)937-5802 (cell). Please let Andrew know if you volunteer anytime other than our COUNT events so that he can count your hours toward our service record.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.

**🪷 Speed Dating Live on Zoom for Singles near Surrey** You get to cycle through rapid one-on-one Zoom dates with Surrey singles matched by age and personality, while the host manages transitions so you can focus on the person in front of you. As part of the process, a two-minute quiz captures your personality — those details are used to identify compatible Surrey singles for your rounds, so the format works harder than any dating app. Once it is wrapped up, we send mutual match results — with nothing shared unless both parties agreed — and you are in control of what happens next. **Your age group, your link:** - **Ages 18-32** → [REGISTER HERE](https://tempodating.com/product?productId=537.0&productType=onlineSpeedDating&city=Surrey&groupurlname=the-collective-for-intentional-social-growth&ar=18-32&face_v=4.0) - **Ages 30-46** → [REGISTER HERE](https://tempodating.com/product?productId=537.0&productType=onlineSpeedDating&city=Surrey&groupurlname=the-collective-for-intentional-social-growth&ar=30-46&face_v=4.0) - **Ages 40-58** → [REGISTER HERE](https://tempodating.com/product?productId=537.0&productType=onlineSpeedDating&city=Surrey&groupurlname=the-collective-for-intentional-social-growth&ar=40-58&face_v=4.0) - **Ages 55+** → [REGISTER HERE](https://tempodating.com/product?productId=537.0&productType=onlineSpeedDating&city=Surrey&groupurlname=the-collective-for-intentional-social-growth&ar=55+&face_v=4.0) **⚠️ Required step:** This rsvp does not equal a reserved seat, so select your age range link above, fill in the registration, and answer the personality quiz — capacity is intentionally small so get in early, and your place is confirmed only once you have done both. --- **Your evening, step by step** 1. **Claim your spot** – by tapping the link for your age group, then finish the compatibility quiz, as the quiz plus registration is what counts. 2. **Jump on Zoom** – by clicking the Zoom link at the event start time, zero setup is required — just open the link, and once you are in the host handles the rest entirely. 3. **Have your dates** – short one-on-one rounds with personality-matched Surrey locals in your group, as the host signals each transition calmly and clearly, and the people in your rounds were sorted specifically for you. 4. **Find your matches** – mutual matches are sent to you privately after the event ends, since non-mutual choices are never shared with either party, and once you have it you decide how and when to connect. **Who shows up:** - Members from Surrey bored of dating apps that go nowhere and want to meet real locals without the faff. - First-timers from around Surrey looking beyond the app treadmill that goes in circles and are serious about meeting someone. - Individuals across Surrey getting away from apps that waste evenings for no return and want to meet real locals without the faff. - Residents from around Surrey looking beyond swiping with nothing to show for it and prefer meeting people in person first. - Locals calling Surrey home getting away from dating apps that go nowhere and are ready for a genuine first impression. **About the Event** - **Format:** Dedicated and hosted via Zoom with back-to-back private rounds per pair, sorted by personality quiz and age for every round. - **Where:** At-home — on any internet-connected device, no special equipment — just a device with a camera and internet, and couch desk or spare room are all equally valid spots. - **Host:** A supportive host guides every round from start to finish, so the evening runs without a hitch — not a single logistical thing is left for you to manage. - **Vibe:** Comfortable video rounds with Surrey singles who are here for the same reason you are, and the host keeps everything comfortable throughout. - **Duration:** Usually sixty to ninety minutes from round one onwards, though times can vary slightly. ⭐ *"Better than expected — way better than anything I have tried before"* – Surrey local, first event 💡 **Worth knowing:** put your phone on silent before joining, and the host takes care of everything else from there, since small prep leads to a noticeably better experience. --- ✨ Done with apps — start here — grab your place above before it goes and we sort the rest this time. See you in the first round. 💕 ✨

**💫 Speed Dating from Home for Vancouver People Done with Apps** Joining means you'll cycle through short private video dates with Vancouver singles age-grouped and personality-curated, while everything stays on track thanks to a live host. When you sign up, a personality questionnaire is built into the sign-up — that information feeds the matching to organise compatible Vancouver locals for your session, which makes every round worth having. After all the rounds, mutual connections are confirmed and shared — with privacy guaranteed for all non-mutual picks — and you take over from there entirely. **Click your age bracket to register:** - **Ages 18-32** → [REGISTER HERE](https://tempodating.com/product?productId=537.0&productType=onlineSpeedDating&city=Vancouver&groupurlname=the-collective-for-intentional-social-growth&ar=18-32&face_v=4.0) - **Ages 30-46** → [REGISTER HERE](https://tempodating.com/product?productId=537.0&productType=onlineSpeedDating&city=Vancouver&groupurlname=the-collective-for-intentional-social-growth&ar=30-46&face_v=4.0) - **Ages 40-58** → [REGISTER HERE](https://tempodating.com/product?productId=537.0&productType=onlineSpeedDating&city=Vancouver&groupurlname=the-collective-for-intentional-social-growth&ar=40-58&face_v=4.0) - **Ages 55+** → [REGISTER HERE](https://tempodating.com/product?productId=537.0&productType=onlineSpeedDating&city=Vancouver&groupurlname=the-collective-for-intentional-social-growth&ar=55+&face_v=4.0) **⚠️ RSVP is not enough:** This rsvp alone will not confirm your attendance, so use your age group link above to register and complete the short personality quiz — spots are kept small by design so register promptly, and your seat is only secure once registration is complete. --- **How the night runs** 1. **Find your age group** – by selecting your age group and following the link, then fill in the personality questions as part of registration, as both are needed to secure your spot. 2. **Join the video call** – by clicking the Zoom invite at the event time, works anywhere with a camera and internet, and everything from that point is handled by the host. 3. **Connect** – live one-on-one video rounds with Vancouver people matched to you by age and quiz, as the host keeps everything smooth and well-timed, as each round is with a Vancouver local matched to your profile. 4. **Check your results** – after the event you will receive any mutual match details, with unmatched selections never disclosed to anyone, and you are in control of everything that happens next. **Who shows up:** - Professionals around Vancouver bored of profiles that never convert to actual dates and want to try something that actually works. - Those living in Vancouver looking beyond unread messages and dead-end conversations and want actual face-to-face conversation. - Someone within Vancouver ready to move past the app treadmill that goes in circles and want to meet real locals without the faff. - Locals based in Vancouver looking beyond digital dating that never converts to anything real and value real conversation over curated profiles. - Members across Vancouver who have had enough of conversations that fizzle before a first date and need a better way to meet people. **Event Overview** - **Format:** Dedicated and hosted over Zoom with back-to-back private rounds per pair, paired by age bracket and quiz results throughout. - **Where:** All online — from your laptop or mobile device, the only requirement is a device with a camera and internet, and you can join from wherever feels comfortable. - **Host:** An engaging host runs the session from the opening to the final round, which makes the whole thing feel effortless — the host owns the evening so you can simply enjoy it. - **Vibe:** Refreshingly easy individual rounds with Vancouver area people who prefer real conversation, and the conversation always feels more real than an app date. - **Duration:** Roughly an hour and a half including the welcome, and the format keeps things moving. 💡 **Useful tip:** close unnecessary browser tabs before the event, because background and lighting matter more than you would think, since small prep leads to a noticeably better experience. --- ✨ Vancouver singles worth meeting are in this event — book your spot above and we will set the rest up for you while places last. See you in the first round. 🥰 ✨
