Quantitative Analysis

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. 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.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences.

Come join us to discuss our July pick "Tusk Love" by Thea Guanzon! Book description: A merchant’s daughter who yearns for adventure gets more than she bargained for when she falls for a broodingly handsome stranger in this saucy romantasy from the New York Times bestselling author of The Hurricane Wars. “A true delight of a book! Spicy and heartfelt—this one is a winner all around.”—Katee Robert, author of Neon Gods As the daughter of an ambitious merchant, Guinevere’s path has been predetermined: marry into a noble house of the Dwendalian Empire, raise her family’s station, and live quietly as a lordling’s obedient wife. But Guinevere longs for a life unbounded by expectations, for freedom and passion and adventure. Those distant dreams become a sudden reality when her caravan is beset by bandits, leaving her guards slain and Guinevere stranded alone on the dangerous Amber Road. Her only chance of survival is to travel alongside Oskar, the aloof half-orc who saved her during the attack. Unlike Guinevere, Oskar’s path is not so set in stone. With his mother dead and his apprenticeship abandoned, all that’s left is a long, lonely walk to a land he’s never seen to find family he’s never met. The last thing he needs is a spoiled waif like Guinevere slowing him down—even if the spark between them sizzles with promise. Despite his cold exterior, Oskar is brave and thoughtful and unlike anyone Guinevere has ever met. And while Guinevere may be sheltered, she brings out a softness in him that he has never dared to feel before. As the flames of their passion grow, they realize that soon they’ll need to choose between their expected destinations or their blossoming romance. Written by New York Times bestselling author Thea Guanzon at the behest of Critical Role’s Jester Lavorre, Tusk Love brings the most romantic story on Exandrian bookshelves to life.
