Data Science

Struggling with motivation and focus as you hammer away on your manuscript at home? Want to join a community of writers as we embrace the joys and pains (mostly pains) of writing together? Bring your laptop, pen & paper, old-school typewriter, or futuristic writing gadget, and join an enthusiastic community of science fiction and fantasy writers as we work on our current projects in the same space. The format will be similar to our online writing sprints: 30-minute blocks of focused, quiet writing time (the sprints), interspersed with breaks where we can chat, ask questions, and share our writing experiences.

🌳🍦 ST. CLAIR WEST VILLAGE WALK, WYCHWOOD PARK, ICE CREAM & MORE! 🍦🌳 Hidden Streets, Storybook Homes & Some of Toronto’s Best Ice Cream Some parts of Toronto feel like you've accidentally wandered into a completely different city. Join us for a relaxed social walk through St. Clair West and the hidden enclave of Wychwood Park — one of Toronto's most unique and exclusive residential communities. Wychwood Park is private, residential, and unlike anywhere else in the city. The homes are all architecturally distinct — no cookie-cutter subdivisions here. Living in Wychwood Park involves a waiting list, board approval, and community guidelines designed to preserve the character of the neighbourhood. It feels almost village-like... peaceful, artistic, and slightly secret. This is not a formal historical tour. It's a social walk with beautiful surroundings, interesting neighbourhoods, and good conversation. 📲 **Join Our WhatsApp Group:**[ Click here to join](https://chat.whatsapp.com/DRFTkxRlHS4B3IL1lMleUd) *** 🚶‍♂️ What We'll Do We'll begin by walking west along St. Clair, taking in the neighbourhood and exploring some of the area's hidden gems. Along the way we'll stop at Dutch Dreams for ice cream — one of Toronto's most famous ice cream destinations. 🍦 From there we'll wander through the winding streets of Wychwood Park before making a stop at Artscape Wychwood Barns to browse the market and community space. Afterward, we'll make our way back toward St. Clair and finish at Grandma Loves You, a local favourite known for some of the best sandwiches in Toronto. 🥪 You are welcome to join us for food or continue back to the subway station. Sometimes the best part of these walks is simply discovering places you never knew existed. *** 🌦️ Weather & Expectations This event happens rain or shine. Please come prepared for outdoor walking and typical Toronto weather conditions. This is an easy social walk suitable for most people. *** 🧢 Meetup Details 📍 Meetup Location: Outside St. Clair West Station by McDonald's 🫎 I'll be wearing my Moose Hat ⏰ Meetup Time: 11:00 AM I will only wait 5 minutes.

5K every week till the snows come down! Or try to! We'll meet by the track. I'll be there early to warm up. We will start the 5K exactly at 9:30am. As mentioned in the About Us, * Using the park track we can all go at our own pace and never really be left behind unless we all finish way ahead of you. :D I think an hour is enough time to dedicate to the run. I'm pretty slow, so you will likely have me around for most of the hour. * Members are free to leave the run whenever they want. * Bring your kids, your pets, your partners, etc. * All encouraged to stick around afterwards and enjoy the park or neighbourhood on your own. * Let's get stronger, healthier and foster a great community at the same time. We also welcome runners who are not in our neighbourhood and want to join us spiritually and run from their own neighbourhoods. :-) Imagine how much healthier and communal the world would be if we all stopped for an hour once in a while to run together; re-centring and re-charging together?

**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. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

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.

**Title**: PySteak: Simulation, Calibration, and Optimization for a High-Steaks Culinary Problem **Details:** Cooking an expensive cut of steak can be a daunting, high-stakes task for a home cook. From traditional pan-searing to reverse searing, cold searing, sous vide, cryofrying, and grill sous vide, many steak-cooking methods can be viewed as attempts to manage the same fundamental tradeoff: * *Exterior flavor and texture:* The surface typically needs to reach roughly 300–330°F to promote rapid Maillard reaction, producing a crisp texture and complex, aromatic flavors. It is often pushed beyond 350°F to induce pyrolysis and develop deeper browning, smoky notes, and char. * *Interior juiciness and texture:* To retain moisture and maintain a tender texture, the internal temperature should stay near the target temperature for the desired doneness, often around 129–135°F for medium-rare. The laws of physics are unforgiving. The heat equation tells us how the high surface temperatures needed to develop the exterior crust create steep temperature gradients that drive heat inward, often resulting in the dreaded gray band of overcooked meat beneath the surface. In this talk, I will share my journey toward engineering a steak recipe designed to develop a deeply browned crust while minimizing the gray band and preserving as much of the juicy, tender interior as possible. No advanced background in mathematics, physics, or programming is required. I’ll start with a brief and accessible introduction to the principles of heat diffusion and how to simulate it on a computer. Then, I’ll explore the role of data (i.e., measurement) in calibrating the simulation model and optimizing the recipe. **Audience Takeaway:** After this talk, the audience will have a basic understanding of how thermodynamics shapes the tradeoff between crust development and an evenly cooked interior, and how heat transfer can be simulated on a computer. They will leave with computational tools they can use to experiment with measurements, calibration, and optimization, giving them a practical starting point for engineering steak-cooking protocols tailored to their own preferences and equipment. **Zoom: This is a *hybrid* event.
