The MLAI Meetup is a community for AI researchers and professionals which hosts monthly talks on exciting research. Our format is: * 6:00 - 6:20: Socializing * 6:20 - 6:40: Announcements and AI news * 6:40 - 7:40: Talk(s) and Q&A * 7:40 - 8:00 Networking * 8:00: Head to the nearest pub for dinner Joint event with the Statistical Society of Australia! **Felicia Bongiovanni: "Inferring Time of Infection Based on Antibody Data Through a Hierarchical Bayesian Framework"** **Abstract:** Time-since-event prediction is a powerful tool to reconstruct histories of an event. It is commonly used in biomedicine to predict the beginning of tumor growth, to predict how long ago someone was infected with a disease, and even to predict the time since death for criminal investigations. Inference through Bayesian statistics and mathematical modelling can allow for time-since-event prediction and provide insight into the mechanisms driving an event. Machine learning is also used for time-since-event prediction but lacks the mechanistic insight Bayesian inference can provide. However, Bayesian inference, especially through Markov Chain Monte Carlo methods, can be computationally expensive and time-consuming. In this talk, I describe a method for combining Bayesian inference with machine learning to improve computational efficiency while also maintaining mechanistic insight. This is demonstrated through the case study of estimating time-since-infection using antibody data. **Speaker bio:** Felicia is a PhD candidate at The Walter and Eliza Hall Institute of Medical Research where she is conducting mathematical modelling of the immune response to understand more about infectious disease dynamics. In another life, she was a data analyst for the National Health Funding Body in Canberra through the Australia Bureau of Statistics Data Graduate Program.

**Topic: Engineering AI Agentic Systems: Decisions, Tradeoffs, and Production Reality** Agenda: 6:00 PM – Networking and refreshments 6:30 PM – Presentation commences 7:15 PM – Q&A 7:30 PM – Networking and refreshments 8:00 PM – Event concludes **Abstract:** Everyone can get an agent working in a weekend. Shipping one to production is a different problem. This talk is a systems engineering lens on agentic AI, starting from the moment a single LLM call becomes a decision loop through the architectural tradeoffs that determine whether it survives contact with reality. We'll cover the control spectrum between deterministic workflows and autonomous agent loops, multi-agent coordination, state management, and what a real control plane looks like beyond rate limiting and logging.We'll also cover the failure modes that don't appear in demos: runaway costs, missing stopping conditions, and observability gaps. You'll leave with a framework that treats human-in-the-loop design, model selection, and control plane engineering as first-class architectural decisions, because agentic systems are not prompt engineering problems. They are systems engineering problems.

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

We will cover metadata-driven approach to building and operating data pipelines at scale on AWS. Discuss architecture, design trade-offs, and lessons learned from running a unified pipeline across multiple customers using configuration-driven workflows. **Presenter: Dilshad Nasirov** Seasoned Software Architect and cloud practitioner with 20+ years of experience building scalable systems and data platforms.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

Dear Illinois Prairie PUG members, Our next meetup will take place in a **new location**. Please read **the whole announcement** carefully to note all the changes. Our new meeting place is **Chicago Innovations at 1 W. Monroe**. *Talk Title*: pg_lake: Unifying transactional and analytical data with Postgres *Speaker*: Elizabeth Christensen, Snowflake *Talk Description* The data world used to be defined by “transactional" (OLTP) and “analytical” (OLAP) workloads, but we’ve asked ourselves, “Why not both?” A new series of extensions called pg_lake has just been released to connect Postgres to object storage and open table formats - like csv, Parquet, and Iceberg. pg_lake bridges the two worlds of transactional and analytical data for a vendor neutral, open source, unified data stack. This talk will explore the pg_lake extension, including how to build it, and demos of using it with modern data workloads in object storage like Amazon S3. We’ll create simple data pipelines with no ETL and high performance analytics. pg_lake is more than just an extension. It is the foundation to a fully unified data path with 100% open source tools backed by PostgreSQL, DuckDB, Iceberg, and Polaris. *Agenda* 5:20 - doors open 5:30 - pizza arrives 6:00 - 6:10 - Hettie D. Opening remarks 6:10- 6:20 - Hettie D. Data warehouse history overview 6:20 - 6:50 Elizabeth C. pg_lake: Unifying transactional and analytical data with Postgres 6:50 - 7:00 Q&A 7:00 - 7:50 - Open discussion and networking 7:50 - 8:00 - Cleanup time and closing *Notes about our new venue*. I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities. You will notice the change in the RSVP form. We are thankful to our hosts and promise to be responsible. We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/). We do not want to waste food, so please indicate your dietary preferences. We will not close the RSVP in the morning of the meetup, but please do your best to RSVP in advance so that we can order the appropriate amount of food and drinks. Also, all meetups will be hybrid - please don't forget to indicate whether you are attending in-person or virtually. Thank you, and I look forward to seeing you all at our new location!

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
