**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.

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.

The optimum computing machine is a subject many of us have studied. If you were building one how would you design it? First the computer should be able to compute with perfect accuracy on any problem in the universe and produce answers which were always and invariably right. Second the computer would have to be swift, working much more quickly than the problem and process could be vocally articulated. Third the computer would have to be able to handle large numbers of variables and large numbers of problems simultaneously. Forth, the computer would have to be able to evaluate its own data and there would have to remain available within it not only a record of its former conclusions but the evaluations leading to those conclusions. Fifth, the computer would have to be served by a memory bank of nearly infinite capacity and would have to be available to the analytical portion of the computer in the smallest fractions of a second. Sixth, the computer would have to be able to rearrange former conclusions or alter them in the light of new experience. Seventh, the computer would need no exterior director, but would be entirely self determined about its programing guided only by the necessity –value of the solution which it itself would determine. Eight the computer should be self servicing and self arming against present and future damage and would be able to estimate future damage. Ninth the computer should be served by perception by which it could determine necessity –value. Tenth ,the memory bank should store perceptions as perceived ,consecutive with time received with the smallest possible time divisions between perception .It would then store in color-Visio (moving),tone audio (flowing),odor ,tactile and self sensation ,all of them cross –coordinated . Eleventh, for the purposes of solutions, it would have to be able to create new situations and imagine new perceptions hitherto not perceived and should be able to conceive these to itself in terms of tone –audio ,color-visio ,odor, tactile, and self sensation –and should be able to file anything so conceived as imagined ,labeled “memories” Twelfth, the entire machine should be portable. It might be somewhat astonishing at first to conceive such a computer .But the fact is, the machine is in existence .There are billions of them in use today and many ,many more billions have been made and used in the past . In fact you’ve got one .for we are dealing with the human mind. L.RON .HUBBARD Do you want to learn how the mind works?Then do not miss this meetup. RSVP now !!

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
