📅 **Week 4 Focus: Calling LLM via API** Each 7-week cycle focuses on a small, well-defined part of a larger system—and over time, these cycles build toward a complete, real-world project Feel free to join at any week and we will catch you up. There is no need to be at the beginning of the cohort to build. Complete beginners welcomed! 📌 By the End of a Full Cycle, You should Have 🎯 A working project in your own GitHub repo 🎯 A small but real portfolio piece you can demo or write about 🧠 **Current Project** This cycle’s shared project is an **image-based knowledge extraction system**. In Week 3, we trained a deep learning object detection model (YOLO) and learned how modern computer vision models are built. **In Week 4** we will try **LLM-based image understanding via APIs** to extract structured information from images and comparing this approach with traditional computer vision and building your own deep learning methods. * \*\*\* **👋 Who Is This For?** 🔹 Beginners who learn best by doing — no prior experience needed 🔹 Career switchers from product, engineering, design, marketing, or other fields who want to break into data 🔹 Analysts, engineers, and PMs looking to sharpen their skills or build real-world projects 🔹 Data professionals who want a creative playground outside of work 🔹 Anyone with big questions and a love for learning through experimentation \*\*\* **BUILD.

Für Mitglieder von Text Collective Berlin ist die Teilnahme an dieser Veranstaltung kostenlos. Nicht-Mitglieder werden um eine Spende von zehn Euro gebeten. [https://textcollective.de/ticket](https://textcollective.de/ticket) Es handelt sich um einen moderierten Workshop. Kreative Schreibübung mit anschließender Diskussion zum Erfahrungsaustausch, Inspiration und Motivation zu sammeln. Ein Raum für alle, die kreativ schreiben möchten – egal ob du gerade erst anfängst oder schon länger schreibst. **Jeden zweiten Samstag des Monats von 14:30 Uhr bis 16:30 Uhr in Charlottenburg (Haus am Mierendorffplatz).** **Was dich erwartet:** In unseren Treffen arbeiten wir mit abwechslungsreichen Schreibimpulsen, die neue Perspektiven eröffnen und spielerisches Experimentieren ermöglichen. Du schreibst direkt vor Ort, teilst deine Texte mit der Gruppe (freiwillig!) und erhältst konstruktives Feedback. Die Atmosphäre ist offen und unterstützend. Hier darf ein Text noch unfertig sein, eine Idee noch roh, ein Gedanke noch unausgereift. In dieser Atmosphäre gegenseitiger Wertschätzung entsteht der Mut, sich auszuprobieren und die eigene Stimme zu entdecken. Wir lesen einander vor, geben Rückmeldung, ermutigen uns gegenseitig und praktizieren das Zuhören. **Über Text Collective Berlin:** Wir sind eine kreative Schreibcommunity, die regelmäßige Workshops und Lesungen organisiert. 2025 erschien unsere erste Anthologie "Begegnung zwischen Welten" mit Texten aus der Schreibwerkstatt.

We've turned the entire learning experience into ***Comprehensible Input* through both simplified and traditional manga** with support for **Zhuyin**, **Pinyin**, **flashcards**, **audio**, **direct translation**, an integrated dictionary. We also specifically design region-specific language to reflect real-life usage in both **mainland Chinese Mandarin** and **Taiwanese Mandarin**, allowing you to naturally compare and explore the differences between the two, so you don’t end up saying something that makes perfect sense in Beijing, but gets you funny looks in Taipei 😏. Now, together with our good friend Matthias from **[Gemeinsam Chinesisch & Deutsch lernen](https://www.meetup.com/gemeinsam-mandarin-chinesisch-und-deutsch-lernen/events/308204343/?eventOrigin=group_upcoming_events),** we’re inviting you to our very first **in-person Mandarin Learner Meetup in Berlin** together!

**Step right up for a fortune-telling experience that's barely accurate, but definitely unforgettable.** Magdalena, the "fortune teller", combines a crystal ball, questionable predictions and a healthy dose of dark humour in a show that's as absurd as it is entertaining. Described by the 'Scotsman' (top newspaper in the UK) as 'unexpected, clever, ridiculous but great stuff, crystal ball and all', this interactive comedy has left audiences worldwide laughing and wondering what just happened. Some say it's life-changing, others call it pure nonsense-but no one escapes without a few laughs, some spirit summoning and answers you probably didn't want. **Sold out run in Edinburgh Fringe Festival 2025** Reserve your seat for just €2, and at the end of the show, you decide what it was worth (suggested contribution: €10-15). Reservations are held until 10 minutes before the show starts. This is a paid show—you just get to choose how much to pay. **Make sure to reserve your ticket [HERE](https://www.eventbrite.co.uk/e/01-accurate-english-comedy-night-tickets-1975608368813?aff=meetup)**

Join us for chill **indoor** beach volley! 🏐 🏐 🏐 This event is for everyone who enjoys chill games and is not a *complete* beginner (A1.5+). We play 3v3 (or 4v4) with beach rules. There are no trainers at this event. Register via [the simultaneous event](https://www.meetup.com/berlin-volley/events/) for higher-level 2v2 matches (F1+). After playing, you can join us for socials with drinks and snacks at the bar area. We often play a social deduction game, which you're also welcome to join. We play in domes that are heated up to at least 15C. It's recommended that you come 10 minutes early so you have time to change and find the fields. If it is your first time, 15 minutes might be even better. You can join whatever court you like and move between courts during the event. We self-organize, so once you finish a game, you can start a rematch, mix with another court, or take a break as you see fit. Upon arrival, join the warmup happening on one of the courts.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
