Machine Learning

The **Digitec Galaxus Product Development Meet-Up** is back — this time diving into **recommender systems** with two talks bridging data science and engineering practice. **Talk 1: Insights from Building and Operating a Recommender System for Migros Supermarkets** *Max Nolte – Data Scientist & Team Lead at Supermarkt IT, Migros-Genossenschafts-Bund* When you think of a Migros supermarket, you don't usually think about recommender systems. Over the past four years, my team and I have built and operated the engine behind personalized Cumulus coupons and a few other digital touchpoints. I'll share how it works, why we invest in it at a brick‑and‑mortar retailer, and what we've learned, covering data, models, measurement, and the practical realities of running it day to day. **Talk 2: Recommendations at Digitec Galaxus — From Data Science to Engineering Practice** *Michael Weiss, Senior Software Engineer & Robert Rosenbach, Senior Data Scientist – Digitec Galaxus* How do you go from a promising model to a recommender system that is fast, scalable, and maintainable in production? We will walk through the Digitec Galaxus recommendation stack end to end: the engineering architecture that keeps recommendations snappy and reliable, and the data-science side of model training — what to optimize for, which input signals matter, and the trade-offs involved in both. The two presentations will take roughly a combined hour, leaving plenty of time for discussions, questions, and exchange afterwards over drinks and snacks. Whether you come from a software engineering, data science, product, or any other background — we'd love to have you join us!

PLEASE PURCHASE **CHF 59 (early bird)** TICKET VIA [LUMA](https://luma.com/rii1rycb). Most AI workshops show you slides. This one gives you something to take home. ​In 2-3 hours you'll build a personal AI assistant that actually knows how you work: what drains you, how you prioritise, what you keep forgetting. No coding. No fluff. Just your laptop and one problem you wish would solve itself. ​You leave with something working. Tonight. ​**What to expect:** You'll learn how to build your own AI assistant using Claude and taking advantage of Claude skills and MCP connectors. All whilst you get to sip on your Aperol (or San Bitter as an alcohol-free alternative). **What to bring** A Claude account (free plan works). Claude Pro recommended if you want to go further on the night. ​**Works even better if you use one of these:** Notion, Asana, Linear, Jira, Google Drive, Gmail, Slack, ClickUp, [Monday.com](https://monday.com/). Claude connects directly to all of them, so your assistant can see your actual tasks without you pasting anything. **In Hottingen, Zurich, detailed location will be revealed after ticket purchase via [luma](https://luma.com/rii1rycb).** ​Don't use any of these? No problem, you'll still build something that works.

It all sounded straight forward. Then the project started... Join us for an informal evening with fellow Agile practitioners, Scrum Masters, project managers, coaches, and anyone working with change, delivery, or transformation. We’ll meet at a local pizzeria, have some good food, and talk about the things that usually come up once the theory meets reality — challenges, lessons learned, different approaches, and questions we’re still figuring out. Nothing formal, just a chance to exchange ideas, meet people from the community, and have interesting conversations. Because some of the best discussions don’t happen in meeting rooms. They happen in the second floor private room of a pizzeria. 🍕 **The venue:** Da Raffaele brings a slice of Naples to the heart of Zürich's Altstadt. Think 48-hour dough, a 500°C wood-fired oven, and an amazing pizza. Two minutes from Central, close to HB — easy for everyone coming from across the city or the S-Bahn.

Together with my colleagues at Digitec Galaxus' recommendations team, we’ve recently taken over the **Zurich Recommendation Systems** meet-up group and consider reviving it as a regular series. To kick things off, we're joining forces with the **Digitec Galaxus Product Development Meet-Up** for an evening on recommender systems in practice. We will present two talks: * **Max Nolte (Migros Genossenschaftsbund)**, amongst other things, on four years of building and operating the engine behind personalized Cumulus coupons — covering data, models, measurement, and the practical realities of running it day to day at a brick-and-mortar retailer. * **Michael Weiss and Robert Rosenbach (Digitec Galaxus)** on the full recommendation stack in Switzerlands leading e-commerce platform — from the engineering architecture that keeps things fast, scalable, and maintainable, to insights from model training: what to optimize for and which inputs matter the most. Each presentation will take roughly 30 minutes, including questions, leaving plenty of time for discussion and exchange afterwards. To participate, please sign up for the events in both groups: * **Digitec Galaxus Product Development Meet-Up** — Primary organizer: This is the sign-up that counts, and you’ll also find a more comprehensive announcement of the talks there ;-) [https://www.meetup.com/digitec-galaxus-zuerich/events/313707996](https://www.meetup.com/digitec-galaxus-zuerich/events/313707996) * **Zurich Recommendation Systems** (i.e., this event) — to help us gauge interest in running this as a continuous series going forward Looking forward to seeing you there!

Hello everyone, Since there will be sun, I changed the location to Zürich Buchlern. Therefore, we will also get 2 fields :) During this event, you’ll have the chance to meet new people, play friendly matches and learn the basic techniques, if you wish. This event is aimed at everyone that has never played before or a long time ago and is not sure to be able to pass the ball properly over the net or to someone. If you think you're comfortable playing, I invite you to join the advanced events of Marius: https://www.meetup.com/meetup-group-avsypajv/. Let's meet on Court 1 and 2 at the Buchlern sports centre in Zurich. **Tips:** \- Bring a water bottle \(there’s a drinking fountain next to the courts\) \- Bring sunscreen/sunglasses/a cap \- The court can usually be watered\, except in rare cases — so it’s good to bring suitable socks if it’s hot **A few practical details and participation conditions:** \- A small contribution is required for court rental and other organisational expenses\, please pay before the event via TWINT at \+41784053495 by **writing your name and date of the event** or cash the day of the event. \- Please only sign up through Meetup for an easier organisation \- Please cancel at least 24 hours in advance if you can’t make it\, so others can sign up or I can reschedule the session \- If you don't cancel and do not show\, please cover your share to keep it fair for everyone\. **Price per person:** CHF 6.5 **!No shows!** Lately, there has been quite some no-shows. Therefore, I remind you to please sign out 24 hours before the event if you're not sure to come. So that people in the waiting list can join instead. The court is not free, any no-show means wasted cost. In case of two no-shows, I have no choice but to impeach you from signing up again by excluding you from the group 😣 If you want to join the Whatsapp group for any updates, events and other activities, let me know after the event 😊

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.

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

If you enjoy knitting, crocheting, working with yarn, this is the group for you. Meet new friends, bring your projects, learn from others.
We normally meet a few times a month during the week from 6-8pm. We will occasionally meet on weekends during daytime hours.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.
