Crowdsourcing

Join us for a relaxed evening focused on hanging out and having a good time. We’re getting together to enjoy some ping pong, kicker, darts, and board games in a very casual setting. It doesn't matter if you’re a regular player or have never tried these games before; the night is really just about the social vibe, not how well anyone plays. You’re welcome to jump into a game whenever you like or just grab a seat and chat with others. It's a nice chance to meet some new people and enjoy the evening in a way that’s easygoing and friendly. See you!

Join our in-person meetup on April 24th to hear talks from experts on cutting-edge topics across AI, ML, and computer vision. **[Register to reserve your seat.](https://voxel51.com/events/berlin-ai-ml-and-computer-vision-meetup-april-24-2026)** Space is limited! **Date, Time and Location** Apr 24, 2026 5:30 PM - 8:30 PM [MotionLab](https://motionlab.berlin/) Bouchéstraße 12/Halle 20 12435 Berlin **Kaputt: A Large-Scale Dataset for Visual Defect Detection** We present a novel large-scale dataset for defect detection in a logistics setting. Recent work on industrial anomaly detection has primarily focused on manufacturing scenarios with highly controlled poses and a limited number of object categories. Existing benchmarks like MVTec-AD (Bergmann et al., 2021) and VisA (Zou et al., 2022) have reached saturation, with state-of-the-art methods achieving up to 99.9% AUROC scores. In contrast to manufacturing, anomaly detection in retail logistics faces new challenges, particularly in the diversity and variability of object pose and appearance. Leading anomaly detection methods fall short when applied to this new setting. To bridge this gap, we introduce a new benchmark that overcomes the current limitations of existing datasets. With over 230,000 images (and more than 29,000 defective instances), it is 40 times larger than MVTec and contains more than 48,000 distinct objects. To validate the difficulty of the problem, we conduct an extensive evaluation of multiple state-of-the-art anomaly detection methods, demonstrating that they do not surpass 56.96% AUROC on our dataset. Further qualitative analysis confirms that existing methods struggle to leverage normal samples under heavy pose and appearance variation. With our large-scale dataset, we set a new benchmark and encourage future research towards solving this challenging problem in retail logistics anomaly detection. The dataset is available for download under [https://www.kaputt-dataset.com](https://www.kaputt-dataset.com). *About the Speaker* [Sebastian Höfer](https://www.linkedin.com/in/sebastian-h%C3%B6fer-891178121/) is an Applied Science Manager at Amazon Fulfillment Technologies & Robotics, leading machine learning and computer vision research for large-scale robotics and warehouse automation. He received his PhD from the Robotics & Biology Lab at TU Berlin, focusing on Sim2Real transfer and robotic perception. His recent work, “Kaputt: A Large-Scale Dataset for Visual Defect Detection” (ICCV 2025) [37], established a major benchmark for industrial anomaly detection, reflecting his expertise at the intersection of academic research and real-world deployment. **Data Foundations for Vision-Language-Action Models** Model architectures get the papers, but data decides whether robots actually work. This talk introduces VLAs from a data-centric perspective: what makes robot datasets fundamentally different from image classification or video understanding, how the field is organizing its data (Open X-Embodiment, LeRobot, RLDS), and what evaluation benchmarks actually measure. We'll examine the unique challenges such as temporal structure, proprioceptive signals, and heterogeneity in embodiment, and discuss why addressing them matters more than the next architectural innovation. *About the Speaker* [Harpreet Sahota](https://www.linkedin.com/in/harpreetsahota204/) is a hacker-in-residence and machine learning engineer with a passion for deep learning and generative AI. He’s got a deep interest in VLMs, Visual Agents, Document AI, and Physical AI. **Most AI Agents Are Broken. Let’s Fix That** AI agents are having a moment, but most of them are little more than fragile prototypes that break under pressure. Together, we’ll explore why so many agentic systems fail in practice, and how to fix that with real engineering principles. In this talk, you’ll learn how to build agents that are modular, observable, and ready for production. If you’re tired of shiny agent demos that don't deliver, this talk is your blueprint for building agents that actually work. *About the Speaker* [Bilge Yücel](https://www.linkedin.com/in/bilge-yucel/) is a Senior Developer Relations Engineer at deepset, helping developers build agentic AI apps with Haystack. Passionate about AI, she makes complex concepts approachable through hands-on tutorials, both online and at real-life events. **Operationalizing Computer Vision for Overhead Lines: Beyond the Demo** At first glance, visual inspection of high-voltage power lines seems straightforward: collect imagery, run one or two AI models, and report the findings. In practice, moving beyond a proof of concept reveals a range of issues that can make or break a campaign. Common concerns include data quality and coverage, scarcity of the most relevant cases and abundance everywhere else, variations in pylon geometry and asset types across regions, calibration and GIS alignment challenges, and a long tail of edge cases that emerge in real-world operations. This talk introduces Siemens Energy’s end-to-end overhead line inspection solution and shares key learnings from inspecting more than 10,000 km of power lines for real customers across several continents. We will show how raw 2D/3D data is transformed into structured information, delivering insights into asset inventory as well as defects, and supporting maintenance and planning decisions for critical infrastructure. The focus is on the combination of algorithmic building blocks and scalable processing, designed for robustness and consistency at scale, where even low error rates can become operationally significant. *About the Speaker* [Stefan Wakolbinger](https://www.linkedin.com/in/stefan-wakolbinger-aa0ba874/) is the Development Team Lead for AI & Analytics at SIEAERO, Siemens Energy's digital powerline inspection service. He leads the development of cutting-edge AI and analytics solutions that transform aerial powerline inspection through multi-sensor technology. His team creates digital twins of powerline infrastructure, automates fault detection, and monitors vegetation management—making powerline inspection safer, more precise, and more efficient. Stefan has been driving innovation in this role since September 2022. **Search your video library like a database** Drop in YouTube URLs or upload files and query content four ways: exact keyword matching, semantic search across transcripts, visual scene search via SigLIP2, and LLM-generated answers that synthesise across segments.

The human habit of indulging or investing devotion, time and attention to something external is as old as civilisation. We may think that its slowly disappearing, but when observed carefully, its just changing forms. The discussion this time would be about how humanity's investment of time and attention rapidly shifted from gods to screens, from creation and contemplation to mindless consumption. Technology didn't replace religion, it become one. Instead of sacrificing a lamb, goat, horse or whatever, you sacrifice your time and sanity. We'll start with short introductions from everyone attending. The focus will be on historical, scientific and philosophical discussion rather than contemporary political debate (*you'll recognise me by my black coat)*

Hey Balkaneros! I’m so excited to announce that we’ll be dancing the night away once again at **Robert Šoko’s Balkan Beats DJ set**! Before the party, we’ll meet up for a relaxed chat and a drink to get into the vibe together at Eingang Zwei Bar - Mehringdamm 57. 🎟 Grab your tickets here: [https://www.tixforgigs.com/Event/71969](https://www.tixforgigs.com/Event/71969) See you on the dance floor! Ellenit P.S. Don't miss *Balkan Beats — An Oral History,* a must-read for every Balkan music lover! [https://balkanbeats-book.com/](https://balkanbeats-book.com/)

The "classical" bookswap is simple: * We meet in a café and put the book(s) we brought down on the tables. * We browse and discuss the books with one another while sipping coffee or hot chocolate, or eating cake. * We write our names down on any books we’d like to take home (post-its and pens provided). * At the end of the evening, negotiate any books that are contended and take a new-to-you book home! Books/happiness shared are books/happiness multiplied! A Bookswap is 10 times better than a Book Club because you can talk about ALL the books instead of just one! This is a great way to give your books a new home and make room for new books: that book you feel guilty for not having read even though it's been sitting on your bedside table for the last 5 years, the book you liked but didn't love, the book you loved so much you want everyone to read it, the book you somehow own three copies of, that book you absolutely hated even though everyone else loves it, and so on. Moreover, you will meet fellow readers, get a new book or two, and several book recommendations. We’ve often had readers experience books they wouldn't normally buy and enjoy it. GROUP EXPECTATIONS for PLEASANT SWAPPING * Please bring a book! It's not that you bring one you take one, but do try your best to bring something. * Books stay on the tables, open for sharing, until you are ready to leave so that everyone can have a look. We are notably not first come first serve. Please wait until you are leaving to bag the book. * If two or more people want the only copy of a book, negotiate. Maybe one of you reads it first and then gives it to the others. Or perhaps they have found another book instead. Or leave it to fate and toss a coin. The best part: now you have found somebody whose taste you can really admire. In any case, please don't walk away with a book with several names on it without letting the others know. These negotiations are fun and easy, so don't shy away from a book because there's already a name on it, and feel free to put your name on as many books as you find interesting. It's not that you bring one you take one; you may take as many as you can negotiate. * Political discussions with consent: make sure the people you are talking to would like to have a political discussion with you. * Please respect this space as first and foremost a community for connecting readers over their love of books and reading, stories, and narratives of all sorts. Please be respectful of tastes and opinions. * If something is bothering you, please reach out to the organizers, and we'll do our best to resolve it. * Lastly, don't expect your book back. It will find a new home. If you love it, let it go. Major LANGUAGES (and genres) of this meetup: English, German, French, Spanish, Italian; Fiction, Non-Fiction, Serious Reading, Light Fun, “classics", Krimis, Booker winners, Sci-Fi, Fantasy, Self-Help and more. You never know who can read what languages, and there's no accounting for taste. We are a delightful and international group of readers. We look forward to swapping with you!

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 Sunday Worship at the American Church in Berlin!** The American Church in Berlin (ACB) is an **ecumenical Protestant congregation** where people from *many* Christian traditions worship together—Lutheran, Reformed/Presbyterian, Anglican/Episcopal, Methodist, Baptist, non-denominational, Roman Catholic, and even a few Eastern Orthodox members. Wherever you come from, you’ll find a place where you can feel at home. Our worship is **traditional and liturgical**, rooted in the rich patterns of the Christian church and easy for both Protestants and Roman Catholics to enjoy. We celebrate **Holy Communion every Sunday and every festival day**, and all baptized Christians are welcome at the Lord’s Table. ACB is an **extraordinarily diverse congregation**, with members from around the world. On any given Sunday you’ll find long-time Berlin residents, young adults, teenagers who attend on their own, families with children, seniors, and many visitors and tourists passing through the city. Our community is known for its **warm and friendly fellowship**—it’s one of the things people talk about most after visiting. Some folks dress formally and others show up in jeans and sneakers; we sit side by side without judgment. **Come exactly as you are.** Most importantly: **our welcome is for everybody—EVERYBODY.** If you’re looking for a church home, a place to pray, just looking to connect, or simply a peaceful hour of worship during your travels, you’re invited. We’d love to welcome you this Sunday! [ACB website](www.americanchurchberlin.de)

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics & Scientology life improvement center.
