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 "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!

**Cuddling as Collective Care – all genders** for **LGBTQIA+** **[Book a Ticket](https://wearevillage.org/en/shop/regenerative-touch/w11-2026)** **Member: 15 €** **Regular: 30 €** This Cuddle Puddle offers a safe, consent-based space for people of all genders within the LGBTQIA+ community to experience non-sexual touch, communal connection and rest. Guided exercises support emotional wellbeing, boundaries, and self-awareness. **Cuddle Puddles** are structured, guided spaces where people can experience the benefits of non-sexual touch — such as reduced stress, nervous system regulation, and a deeper sense of belonging. Touch, when consensual and caring, can support emotional resilience and mental health. This **Cuddle Puddle** is open to all genders within the LGBTQIA+ community, creating a space where diverse identities can meet beyond gendered expectations. A non-gender-restricted setting allows for broader empathy, mutual understanding, and connection, while honoring individual boundaries, choice, and safety at all times. **General Information** • This format is for all queer people (LGBTQIA+) interested in experiencing touch in a safe(r) setting. • This is a clothes-on format. • Bring a sheet and towel to cover cushions, mats, or massage tables. • This event will be in English • This event is also available at a reduced member price – but not part of the three-free-monthly-events benefit. • Concession tickets upon written request to **[events@wearevillage.org](mailto:events@wearevillage.org)** **Kuscheln als kollektive Fürsorge – Alle Geschlechter** für **LGBTQIA+** **[Anmeldung](https://wearevillage.org/shop/regenerative-touch/w11-2026)** **Mitglied: 15 €** **Regulärer Preis: 30 €** Dieser Cuddle Puddle bietet einen sicheren, einvernehmlichen Raum für Menschen aller Geschlechter aus der LGBTQIA+ Community, um nicht-sexuelle Nähe, gemeinschaftliche Verbindung und Entspannung zu erleben. Die angeleitete Erfahrung stärkt emotionales Wohlbefinden, Körperwahrnehmung und klare Grenzen. **Cuddle Puddles** sind angeleitete Räume für bewusste, nicht-sexuelle Berührung, die Stress reduzieren, das Nervensystem regulieren und das Gefühl von Zugehörigkeit stärken können. Konsensuelle Nähe unterstützt emotionale Stabilität und psychische Gesundheit. Diese Cuddle Puddle ist für alle Geschlechter innerhalb der LGBTQIA+ Community geöffnet. Ein nicht-geschlechtergetrennter Raum ermöglicht vielfältige Begegnungen jenseits von Rollenbildern und Erwartungen. So entsteht ein Feld für mehr Empathie, gegenseitiges Verständnis und authentische Verbindung, immer auf Basis von Wahlfreiheit, klaren Grenzen und gegenseitigem Respekt **Was ist Regenerative Berührung?** Regenerative Touch ist ein monatlicher Workshop für Queer People, bei dem wir uns gegenseitig helfen, langsamer zu werden, in unseren Körper zu kommen und in einer unterstützenden und nährenden Umgebung die wohltuende Wirkung von regenerativer Berührung erkunden. Berührung, die im täglichen Leben oft übersehen wird, ist ein grundlegendes menschliches Bedürfnis. In diesen Workshops schaffen wir einen Raum, der ausschließlich ihrer regenerativen und heilenden Kraft gewidmet ist, frei von romantischen oder sexuellen Konnotationen. Berührung kommuniziert direkt und erreicht Orte, die Worte nicht erreichen können. Hast du jemals die beruhigende Wirkung einer warmen Umarmung oder einer tröstenden Hand auf deiner Schulter erlebt? Selbst ein kurzes 15-minütiges Handhalten kann zu einer signifikanten Senkung der Herzfrequenz und des Blutdrucks führen und eine starke Entspannungsreaktion signalisieren. Eine einfache 20-sekündige Umarmung kann zu höheren Oxytocinspiegeln führen, dem Hormon, das mit Bindung und Vertrauen verbunden ist. Jeden Monat wird unser trauma-sensitiver Moderator den Abend um Themen wie Präsenz, Regulierung des Nervensystems und emotionale Sicherheit gestalten und sich auf praktisches Erleben anstatt auf zu viele Worte oder Techniken konzentrieren. Es sind keine Vorkenntnisse in Körperarbeit erforderlich – bring einfach deine Neugier mit. **Vorteile** – Erfahre eine Verringerung von Angstzuständen und Depressionen sowie eine erhöhte emotionale Widerstandsfähigkeit durch beruhigende, achtsame Berührung. – Kultiviere wertschätzende Anwesenheit und tiefere Verbindungen zu dir selbst und anderen. – Unterstütze die Heilung von Traumata und setze in einer sicheren, nährenden Umgebung Emotionen frei. – Verbessere deine Stimmung und deine Immunfunktion, indem du Stress reduzierst und Endorphine freisetzt. – Fördere ein Gefühl von Gemeinschaft und Zugehörigkeit durch gemeinsame, nonverbale Erfahrungen. – Ermutige tieferes Mitgefühl und Akzeptanz durch sanften, unterstützenden Kontakt.

Silent Book Club is a group of book lovers who enjoy reading together in public. All books and all readers are welcome. (Kindly RSVP 'yes' only if you can make it, so we can save a seat for you and our fellow readers on the waitlist!) This page-turning party will unfold in the Café (1st floor) at the Bode Museum. There's no entrance fee, but please order at least one item from the cafe and don't bring any outside drinks :) No quizzes, no pressure, no assigned books - just a group of book-loving souls basking in the beauty of silent reading. **Our thrilling agenda:** 10:30 am - 11:00 am - Arrivals, ordering drinks/food (social time) 11:00 am - 12:00 pm - The Great Quiet Reading Hour (where silence is the star) 12:00 pm - 13:00 pm - Optional socializing, share your reading adventures or just keep exploring the pages Stay for lunch, and who knows? You might just find your next favorite book over a pizza. NB: If you plan to go for lunch, please consider bringing cash, as some restaurants only accept card payments after a certain amount.

This is a 3 phase meetup. You can come at any time. 1.) 6:45 -7:00 p.m.: Gathering at the meeting spot (see gmaps link!) 2.) 7:00 - 7:30 p.m.: Walk & Talk to the Kerb food court. 3.) 7:30 - 10:00 p.m.: Immerse conversations in the Kerb food court. 🪑: Reserved tables for the meetup. **1.) How to the find Quartier 205 Stadtmitte:** [https://goo.gl/maps/6Fhft3LbPhcEsQrdA](https://goo.gl/maps/6Fhft3LbPhcEsQrdA) The exact meeting spot can be seen in the photo below! We meet on the 1st floor where the trash sculpture can be seen. Look for a meetup sign or organizer wearing a black or red lanyard with "staff" written on it. **2.) Walk & Talk to the Kerb food court** The best part. In order to extend the walk we'll stroll all the way to Brandenburger gate and from there to the former Sony Center where we are going to enter the Kerb foodcourt. **3\. How to find the Kerb food court** [https://maps.app.goo.gl/xJTQg9oBoGL67syz7](https://maps.app.goo.gl/xJTQg9oBoGL67syz7) Kerb is located at the former Sony Center. The new flagship food court of Potsdamer Platz. Most likely we will be sitting upstairs on the first floor next to the bar (take the stairs to the left). ***Best ways to get there:*** 1\. U2 \(subway\): Get off at Potsdamer Platz and walk around 7 min to Kerb. 2\. Bus M41 or M85 Get off at Potsdamer Platz and walk 5 min to Kerb. *Who is this meetup for:* 1\. Internationals who want to practice German or any other language\. 2\. Germans who want to improve their language skills\. 3\. Anyone who is interested in cultural exchange and wants to socialize\. *What you can expect:* 1\. A professionally organized meetup that can adapt to any changes given the current situation\. 2\. A Walk & Talk to break the ice\. 3\. A collaborating venue where you can further socialize with other members\. *important:* This event is at the same time and meeting location like the "Asian Languages & Culture Exchange 🍜日本語, 한국어, 汉语🍥" one. So I'm basically organizing 2 events at the same time which means that you can expect way more people than on the list. *** Whenever you attend a meetup, the most common as well as first question you get is: "Where are you from?" You probably heard this question a million times. Well, at least I did. From my own experience of attending over 200 international meetups in various countries such as Germany, Japan, Australia and Thailand, I can tell you that asking for the name is a better approach. “A person’s name is to that person, the sweetest, most important sound in any language.” - Dale Carnegie If you really want to connect with like-minded people you should remember their name, but you don't have to remember every persons name you've talked you. Be picky about that, don't be me who can somehow remember everyones name easily. Don't tell yourself sth. like "I'm bad at remembering names." It's all about developing the habit of asking for a name and keep the conversation going on. Furthermore, you want to learn German or any other language. Learning the local language is crucial to connect with the locals and developing a true friendship. This can be accomplished with immersion. My goal is to inspire you to go out of your comfort zone and improve yourself each time you join this meetup.

RSVP on Luma: [https://luma.com/ou3ks02q?utm_source=Meetup](https://luma.com/ymc3ttfx?utm_source=Meetup) Silent Reading / Creating Club is a gathering for people who enjoy focusing together in public. Bring a book, a notebook, a sketchpad, knitting needles, whatever you’d like to spend a quiet hour doing. All projects and all participants are welcome. We’re building a community of readers and creators who value depth, presence, and shared silence. The reading and creating isn't the real highlight, though, it’s in the people who return and make it feel like a familiar room. (Please RSVP “yes” only if you can make it, so we can save a seat for you and others on the waitlist.) Our Meeting Point is the **W66 Café**. There’s no entrance fee, but please order at least one item from the café and don’t bring outside food or drinks 🙂 No assignments, expectations, or pressure. Just a shared hour of intentional silence, followed by the opportunity for good conversation. 🕰 Our Agenda **10:30 – 11:00** Arrivals, ordering drinks/food, light social time **11:00 – 12:00** The Great Quiet Hour (Read. Write. Sketch. Code. Think. Sit.) **12:00 – 12:30** Optional socializing: share what you were reading or creating, or simply continue in quiet focus. ## 🏡 House Guidelines To keep this space calm and welcoming for everyone: • Silence during the focus hour (no calls or conversations) • Put cellphones on silent mode • If using technology, please avoid meetings or audio (headphones please!) • Arrive before 11:00 if possible to minimize disruptions

Bengali New Year Celebration Step into a new year, Bengali style 🌿✨ Pohela Boishakh marks the Bengali New Year—a celebration of renewal, simplicity, community, and food that is deeply rooted in tradition. This evening is an invitation to experience that spirit in an intimate, thoughtfully curated supper club setting. If you’re new to Bengali cuisine, this is a beautiful place to begin. The menu will center around bhorta—a traditional style of preparing food where vegetables, seeds, and herbs are gently mashed together with mustard oil, spices, and care. It’s humble, soulful, and incredibly expressive of Bengali home cooking. This edition will be fully vegetarian, highlighting the diversity and depth of plant-based dishes in Bengali culture. Each preparation carries a story- of seasonality, resourcefulness, and the art of making something extraordinary from simple ingredients. The full menu will be shared a few days before the event. If you have any dietary restrictions or food allergies, please let us know in advance so we can accommodate you thoughtfully. ✨ What to expect: – A curated cultural dining experience – A chance to learn about Bengali New Year traditions – Warm, communal seating and storytelling through food – A slower, more intentional way to connect over a meal 💳 Contribution: 29.90€ per person Come as you are, bring your curiosity,and celebrate new beginnings with us.

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

Dear Illinois Prairie PUG members, Our next meetup will take place in a **new location**. Please read **the whole announcement** carefully to note all the changes. Our new meeting place is **Chicago Innovations at 1 W. Monroe**. *Talk Title*: pg_lake: Unifying transactional and analytical data with Postgres *Speaker*: Elizabeth Christensen, Snowflake *Talk Description* The data world used to be defined by “transactional" (OLTP) and “analytical” (OLAP) workloads, but we’ve asked ourselves, “Why not both?” A new series of extensions called pg_lake has just been released to connect Postgres to object storage and open table formats - like csv, Parquet, and Iceberg. pg_lake bridges the two worlds of transactional and analytical data for a vendor neutral, open source, unified data stack. This talk will explore the pg_lake extension, including how to build it, and demos of using it with modern data workloads in object storage like Amazon S3. We’ll create simple data pipelines with no ETL and high performance analytics. pg_lake is more than just an extension. It is the foundation to a fully unified data path with 100% open source tools backed by PostgreSQL, DuckDB, Iceberg, and Polaris. *Agenda* 5:20 - doors open 5:30 - pizza arrives 6:00 - 6:10 - Hettie D. Opening remarks 6:10- 6:20 - Hettie D. Data warehouse history overview 6:20 - 6:50 Elizabeth C. pg_lake: Unifying transactional and analytical data with Postgres 6:50 - 7:00 Q&A 7:00 - 7:50 - Open discussion and networking 7:50 - 8:00 - Cleanup time and closing *Notes about our new venue*. I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities. You will notice the change in the RSVP form. We are thankful to our hosts and promise to be responsible. We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/). We do not want to waste food, so please indicate your dietary preferences. We will not close the RSVP in the morning of the meetup, but please do your best to RSVP in advance so that we can order the appropriate amount of food and drinks. Also, all meetups will be hybrid - please don't forget to indicate whether you are attending in-person or virtually. Thank you, and I look forward to seeing you all at our new location!
