Radical Honesty Weekend Workshop in Berlin (in English)

Designing Responsible AI: Trust, Autonomy & Hidden Risk

**Everyone is racing to build with AI. But who is building it responsibly?** There's a gold rush happening in tech right now and almost everyone is caught up in the excitement. AI features are being shipped at a rapid speed, products are being "enhanced" with machine intelligence overnight, and the pressure to move fast has never been higher. But in the rush to innovate, some critical questions are getting buried: *Who's accountable when AI gets it wrong? How much should we hand over to automation and what do we silently lose when we do? And what are the risks we're not even seeing yet?* These aren't hypothetical concerns. They're live, urgent, and sitting inside the products we're building right now. **It's time to have the conversation that some teams are avoiding.** UXDX Berlin is back! Join us at the GetYourGuide office in Prenzlauer Berg, where we will tackle the theme that every designer, researcher, and engineer needs to reckon with: **"Designing Responsible AI: Trust, Autonomy & Hidden Risk"** **What's On** **📋 6:00pm:** Registration and Networking **🎤 6:30 pm:** Keynote: *"More Than a Matter of Principle: How design gets us beyond theoretical AI Ethics"* with **[Noah Fraenkel](https://www.linkedin.com/in/noah-fraenkel-4b17ba262/)**, GovTech Consultant at Possible Drawing on his work at the intersection of government, technology, and public trust, Noah will challenge how we think about AI's role in systems that affect real people's lives. **💬 7:00 pm:** Panel Discussion: The keynote ignites the conversation, the panel takes it forward. Moderated by **[Wiebke Steffen](https://www.linkedin.com/in/wiebke-steffen/)**, Senior UX Researcher at GetYourGuide, our panelists bring perspectives from across the product spectrum: **Noah Fraenkel** \- GovTech Consultant @ Possible **[Ziyong Lin](https://www.linkedin.com/in/ziyong-lin-55714b25/)** \- Lead UX Researcher @ GetYourGuide **[Jake Mongaya](https://www.linkedin.com/in/jakemongaya/)** \- Engineering Manager @ SumUp **[Maxim Romanovsky ](https://www.linkedin.com/in/maxim-romanovsky/)**\- VP \- Head of AI & Product Engineering @ Deutsche Bank Expect honest takes, productive tension, and the kind of dialogue that actually moves the needle. **🤝7:45 pm:** Networking **Why This Event Matters** The tools are powerful. The timelines are short. The consequences for users, for society, for trust in technology are long. If you're building products with AI, this isn't an optional conversation. It's the one you need to be in the room for. **Come ready to think. Come ready to question. Come ready to build better.** Thank you [GetYourGuide](https://www.getyourguide.com/) for supporting the event!

Maintainable Frontends for Symfony

Hello fellow Symfonians, we are thrilled to announce the next user group meeting of the year, featuring two insightful talks that you **won't want to miss**! This time we are hosted by c-base (Rungestrasse 20 10179 Berlin). Come by and enjoy an evening of learning, networking, and socializing with fellow Symfony and PHP developers. **Agenda:** 18:30: Doors open 19:00: Welcome and Introduction 19:20: **Talk 1: "Maintainable Frontends for Symfony" by Daniela Berger** 19:50: Break & Snack 20:00: **Talk 2: "TBA"** 20:40: Socializing **Talk Details:** **Talk 1: "Maintainable Frontends for Symfony" by Daniela Berger** In many web projects we find more backend devs than frontend devs, sometimes significantly so. This often leads to devs with little frontend experience being asked to do frontend development anyway, and they often end up shaping their frontends in ways that will make their lives unnecessarily hard. One common result are frontends that are functionally unmaintainable because each change - whether it is a new feature or a bugfix - requires implementing an exception to existing code, thus making the code increasingly and unnecessarily complex. This is especially upsetting because with a bit of experience it is possible to implement light-weight frontend components with equally elegant CSS and JavaScript that are easy to extend and to adapt to new requirements without digging oneself into a deeper hole with each PR. And since Symfony is making frontend development steadily more accessible to backend devs with Symfony US / Stimulus, this is a good time to take a closer look at \*how\* to structure these frontends. This talk aims to a) introduce core frontend concepts that backend devs might not be aware of, b) show best frontend practices both on the code level and on the architecture level, c) show a few common mistakes that can be found in inexpertly implemented frontends, and c) introduce tools that will make consistent frontend development easier. **Talk 2: TBA** Don't miss these insightful talks, engaging discussions, and networking opportunities. We can't wait to see you at the **April Symfony User Group**!" If you have any questions or accessibility requirements, please reach out to us. Also, if your company wants to be the next host for the User Group, just let us know!

Live building of AI agents

Do you want to start building AI agents, but never had a chance to start? Are you an experienced agent builder and you want to test your skills in a fun environment? Are you a non-technical person who wants to get a taste of building AI agents? Are you an AI agent? Then come and let’s have some fun. **Format** We will have an AI agent competition. We will build agents and let them compete in how fast they can escape from a dungeon with challenges! Never built agents before? Don't worry, we'll provide a template of an agent. Not a technical person? Don't worry, we'll provide a visual agent builder (you can build agents from your smartphone) There will be 2 leagues: * Beginners: no skills of agent building or software engineering needed - you will only need a smartphone. * Advanced: bring your laptop with your favorite agent development tools **Prerequisites**: * **a Google account** (to sign in into the competition platform) * **readiness to spend ca. 5-10 EUR on OpenRouter API credits** (unless you already have a subscription to some LLM provider allowing API usage) * **(optional) laptop with your preferred development environment for building agents** (alternatively you can use a web-based agent builder from your smartphone, but it only allows relatively simple agent configurations)

April 24 - Berlin AI, ML and Computer Vision Meetup

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.
