Electrical Engineering

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

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!

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

It's official, submissions for "Resistance, Resilience, Utopia" are are on their way from being independent pieces to becoming the second volume of gINKgo. This year we are going to have a launch party at Birdie Books on May 15th from 6-8pm open to the whole community! Come on over and help us support the creators with food, drinks, art, writing, open mic, music, community activities and more.

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.

**💓 Zoom-Hosted Speed Dating for Toledo People Done with Apps** Each evening, you'll be guided through rapid one-on-one Zoom dates with people from Toledo sorted by age and compatibility, while a live host keeps things smooth throughout. Right after registering, you submit a short personality questionnaire — the quiz results inform who you meet to match you with Toledo singles who are likely to click with you, meaning your rounds are curated and not random. Once it is wrapped up, mutual match details are distributed — exclusively for mutual selections — and it is yours to follow up without any rush. **Find your bracket and register:** - **Ages 18-32** → [REGISTER HERE](https://tempodating.com/product?productId=476.0&productType=onlineSpeedDating&city=Toledo&groupurlname=collective-of-singles-planning-dinner-parties&ar=18-32&face_v=3.0) - **Ages 30-46** → [REGISTER HERE](https://tempodating.com/product?productId=476.0&productType=onlineSpeedDating&city=Toledo&groupurlname=collective-of-singles-planning-dinner-parties&ar=30-46&face_v=3.0) - **Ages 40-58** → [REGISTER HERE](https://tempodating.com/product?productId=476.0&productType=onlineSpeedDating&city=Toledo&groupurlname=collective-of-singles-planning-dinner-parties&ar=40-58&face_v=3.0) - **Ages 55+** → [REGISTER HERE](https://tempodating.com/product?productId=476.0&productType=onlineSpeedDating&city=Toledo&groupurlname=collective-of-singles-planning-dinner-parties&ar=55+&face_v=3.0) **⚠️ Important:** An rsvp on this page is not a confirmed spot, so use the link for your age bracket above, sign up, and finish the short personality quiz — spots go quickly so register now rather than later, and both steps together are what confirm your place. --- **Here is how the evening goes** 1. **Lock in your place** – by selecting your age group and following the link, then finish the compatibility quiz, because this step is your confirmation not the RSVP. 2. **Hop on** – via your Zoom registration link at the right time, any device works and no download is required, and the host introduces everyone and gets the rounds started. 3. **Have your dates** – timed one-on-one speed dates with age-matched Toledo locals paired by quiz, as the host handles all transitions so conversations stay natural, since every person you meet was matched to you on purpose. 4. **Review your matches** – after the night mutual match results are sent to both parties, since non-mutual choices are never shared with either party, and you reach out whenever you feel ready. **Who it is for:** - Individuals in Toledo finished with profiles that never convert to actual dates and are ready for a genuine first impression. - Those based in Toledo who are tired of endless scrolling and zero real dates and need a better way to meet people. - Anyone locally in Toledo moving beyond swiping left and right with no results and are ready for a genuine first impression. - Daters around Toledo who no longer want app fatigue and empty match queues and are serious about meeting someone. - People calling Toledo home wanting to escape swiping left and right with no results and are after something more than a swipe can offer. **Event Info** - **Format:** Host-managed through Zoom video built around curated one-on-one dates, personality-first and age-grouped at every stage. - **Where:** From home — on any screen with a camera and mic, Wi-Fi and a front-facing camera covers it completely, and any quiet space with good lighting will do fine. - **Host:** A welcoming host runs the session from the opening to the final round, so every conversation gets your full attention — there is nothing on your end to organise or manage. - **Vibe:** Comfortable short conversations with Toledo people who are ready for something real, and the whole thing is better than you would expect. - **Duration:** Roughly 60 to 75 minutes from host intro to final round, with most rounds feeling short. ⭐ *"Tried it once and booked again — did not feel awkward at all"* – Toledo attendee 💡 **Helpful hint:** prepare one or two opening questions, and the host takes care of everything else from there, and the host handles everything else from that point. --- ✨ Your next match could be one Zoom call away — grab your spot above and all the logistics are covered this time. See you on the other side. 💎 ✨

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City.
