Hi Deep Learners, It took us a while, but our next Deep Learning Meetup is taking place on **April 28** at Frequentis. Our topics this time are: Zero-Shot Forecasting with TiRex and Responsible Annotation Services. \*\*\* **Agenda:** * 18:15 Arrival * 18:30 **Introduction** by the meetup organizers * **Welcome** by the host: Frequentis * 18:45 **Talk 1:** **TiRex: Zero-Shot Forecasting Across Long and Short Horizons with Enhanced In-Context Learning** by Sebastian Böck *(NXAI GmbH)* * 19:30 **Announcements** * **Networking Break** * 20:00 **Talk 2:** **Combining technological precision with social responsibility in training data preparation** by Andreas Schachl *(Responsible Annotation Services)* * 20:45 **Networking** * \~21:30 **Wrap up & End** \*\*\* **Important Arrival Information:** * the closest metro stop is U6 Tscherttegasse; however, the track is closed in direction Siebenhirten: you'd have to go to next stop (Schöpfwerk) and then ride 1 stop back * Alternatives: * from U6/S Meidling: 15 min walking * Badner Bahn: Am Schöpfwerk * by bike * if you arrive by car: parking spots available **Talk Details:** **Talk 1:** **TiRex: Zero-Shot Forecasting Across Long and Short Horizons with Enhanced In-Context Learning** TiRex is a compact pre-trained forecasting model for zero-shot time series forecasting across both short and long horizons. Built on an xLSTM backbone, it combines recurrent state tracking and strong in-context learning with contiguous patch masking and masked inference, enabling robust forecasting and efficient uncertainty estimation. This talk outlines the key architectural and training choices behind the model, including data augmentation strategies and large-scale pre-training. Results on public benchmarks show strong zero-shot forecasting performance together with fast inference and a low memory footprint. The talk also highlights how TiRex representations transfer to downstream tasks such as time series classification, illustrating the promise of forecasting models as broader foundation models for time series. **About the speaker:** Sebastian Böck is Lead Researcher at NXAI, specializing in Deep Learning, Sequence Modeling, and Time Series Forecasting. He received his PhD in Computer Science from JKU in Linz and his diploma degree in Electrical Engineering and Information Technology from the Technical University in Munich. Long before his current focus on the efficiency and scalability of foundation models, he pioneered the application of recurrent neural networks (RNNs) in Music Information Retrieval—spanning onset detection, beat tracking, and polyphonic transcription. This early work cemented his deep expertise in state-tracking and recurrent architectures. Today, his research at NXAI centers on overcoming the fundamental scaling and inference bottlenecks of modern AI through the extended Long Short-Term Memory (xLSTM) paradigm and its application across diverse modalities. **Talk 2:** **Combining technological precision with social responsibility in training data preparation** This presentation introduces Responsible Annotation Services (RAS), a specialized All-Austrian provider of high-quality data processing. Founded as a spin-off of the non-profit Responsible Annotation, RAS leverages a unique workforce of neurodivergent experts to deliver exceptional attention to detail, pattern recognition, and perseverance - helping to create reliable, ethical, and effective AI systems. Three distinct case studies will be presented demonstrating the versatility across modalities and industries: Bank Foyer Safety: A strategic collaboration with KEBA to refine their AI assistant, KeBob. This involved the meticulous labeling of human postures and mobility aid usage to enhance real-time emergency detection in semi-public banking environments. Text Annotation: A dive into our natural language processing project with Newsadoo, showcasing how our team structures complex textual data to train advanced language models with high semantic accuracy. Air-Vehicle Surveillance: A large-scale project with Frequentis involving the annotation of approximately 5 million video frames for airport monitoring, transforming raw footage into precise training data. **About the Speaker:** Andreas Schachl is a seasoned tech leader and open source enthusiast who believes that creating a better future requires action — not just ideas. Together with his friend Hans‑Peter Kranewitter, Andreas co‑founded Responsible Annotation Services, an AI‑focused venture that streamlines the entire data pipeline. Their key to success is a neuro‑diverse team of annotation experts who consistently deliver top‑tier results at high speed, even over prolonged periods. We are looking forward to welcoming you at our April Meetup. Your VDLM organizer team.

A hands-on migration and tuning workshop for DACH engineers moving from cloud APIs to local LLMs. 📅 **28.04.2026 · 17:30 – 22:00 CET** 📍 **fiskaly office — Mariahilfer Str. 36, Wien** ⚠️ **RSVPs are handled on Eventbrite, not Meetup.** Marking yourself as "going" here does not reserve your spot. Please register on Eventbrite 👉 [https://www.eventbrite.at/e/off-cloud-by-sovereign-ai-lab-tickets-1987825036194](https://www.eventbrite.at/e/off-cloud-by-sovereign-ai-lab-tickets-1987825036194) *** **ABOUT THIS SESSION** Your cloud API invoice is climbing. Your compliance team is asking harder questions. You've heard "just run it locally," but nobody has shown you how. And many engineers who already run locally are leaving meaningful headroom on their hardware. This session fixes both problems in the same room. **Two tracks:** 🔹 **Track A — Cloud to Local** For teams currently using hosted LLM APIs who have never run local inference. You walk in with an API key. You walk out with a working local model, a drop-in API swap, and a cost comparison template you can fill with your own workload numbers. 🔹 **Track B — GPU Whispering** For engineers already running local inference engines who want to go deeper than default settings. Quantization, VRAM layout, CPU memory bus saturation, real benchmarks on real hardware. Cross over during open lab. Ask the awkward questions. *** **WHO THIS IS FOR** * Technical founders, CTOs, and engineers whose pay-per-token invoices have become a fast-growing expense line * ML and backend engineers who want to get off the API treadmill * DevOps leads and infrastructure architects already running local models who want to go deeper than default settings * Sectors: healthcare, legal, manufacturing, financial services, media, startups *** **GROUND RULES** ✅ No sales pitches. Ever. ✅ Bring a laptop. If you're already running local models, bring that setup. If not, we'll get you started during doors (17:30–18:00), and a pre-event setup gist goes out the day before. ✅ All skill levels welcome, provided you write code. *** **⚠️ IMPORTANT — HOW TO RSVP** To secure your spot, you **must register on Eventbrite**: 👉 [https://www.eventbrite.at/e/off-cloud-by-sovereign-ai-lab-tickets-1987825036194](https://www.eventbrite.at/e/off-cloud-by-sovereign-ai-lab-tickets-1987825036194) Meetup RSVPs will not be counted toward attendance. See you on April 28th! 🚀

This is a structured coworking session for people who want to follow through and get it done. To join, please register here (takes 1–2 minutes): [https://nocrastination.space/](https://nocrastination.space/) **Execution with Style. You start, but don't finish. We help you get it done.** Join our [WhatsApp group](https://chat.whatsapp.com/K6LidaoQhe16wZ0Se9pNM6?mode=gi_t) Follow us on [Instagram](https://www.instagram.com/nocrastinationclub/) You just haven’t been able to follow through. You start things, lose momentum and find yourself starting over again. You’re not alone. Most people get support at the beginning. And applause at the end. But the part that actually matters? The middle. The quiet, repetitive, sometimes frustrating part where nothing feels exciting, and everything depends on showing up. **That’s where we are.** At NoCrastination, we don’t meet for hype. We meet to **show up and finish something, together.** Not perfectly. Not magically. Just consistently. **Why “Style”?** Because sometimes, the hardest part isn’t the task. It’s who you believe you are when you sit down to do it. When you wear something different, something bold, unusual, or expressive: you step slightly outside your usual identity. And in that small shift… It becomes easier to start. Easier to act. Easier to follow through. **Execution with Style** Each session, you’re invited to wear something you normally wouldn’t: * the jacket that never leaves your closet * something colorful, dramatic, or expressive * something funny, strange, or unexpected * something you feel like you “can’t pull off” No pressure. But if you join in, be ready to share the story behind it. **Self-expression + execution = momentum** **What this really is** This is a space for people who: * keep starting but don’t finish * are building something (or figuring it out) * don’t want to do it alone anymore **What happens here** You bring something you’ve been avoiding. We sit down together. We focus. And you leave with something done. **Why people come back** * “I finally follow through on what I plan” * “I leave with real progress every time” * “This is the only place I actually stay consistent” **Time and location** 🕐 **Every Tuesday, 1:00 PM – 5:00 PM** 📍 **Jaz in the City – Ground Floor Lounge** Windmühlgasse 28, 1060 Vienna 💻 **Bring:** your laptop, journal, or anything you’ve been avoiding ☕ Please do order something from the bar, so as to keep us in their good graces! Espresso: €3.5, Americano: €4.5, Latte: €5.5. Donations to support the community are voluntary and welcome. **How it works** * **13:00–13:30 → arrival + soft intro + set your task** * **Deep focus sessions (2 x 90’ + 15’ breaks)** * Quiet focus + optional social space * Drop in anytime, stay as long as you want Simple structure. Real progress. **First time joining?** Look for **Joanna Liu** near the ground floor bar 💛 We’ll get you settled. **This is for you if:** * You keep starting but don’t finish * You feel stuck working alone * You want structure — without pressure * You want to express yourself AND move forward **What you’ll get** Not motivation. Not a productivity hack. **You’ll get: ONE THING DONE.** And then you come back, and do it again. **This is how it starts** You don’t need to commit to anything big. Just come once. Pick one thing. Finish it. We’ll be there. As we’re growing and improving the experience, we’re moving to a more structured system. Registration is part of participating. **Stay connected** Join our [WhatsApp group](https://chat.whatsapp.com/K6LidaoQhe16wZ0Se9pNM6?mode=gi_t) Follow us on [Instagram](https://www.instagram.com/nocrastinationclub/) This is a space you can keep coming back to. **You’re not behind. You’re just in the middle.** And you don’t have to go through it alone. You are one of us.

Dear Data Enthusiasts, Come to the joint event with Women in AI Austria at UNIQA on the **29th of April** to explore how fragmented, heterogeneous data can be transformed into governed, AI-ready foundations that drive real impact. This evening we will hear how these challenges play out in two very different domains: managing workforce data at scale in insurance, and unifying multi-modal clinical data to support better patient outcomes in healthcare. **From Fragmented to Foundational: People Analytics at UNIQA** How do you turn fragmented People Data into a trusted, AI‑ready data foundation? This session shows how UNIQA uses Databricks as a core data platform for people analytics, integrating multiple sources into a governed People Datawarehouse. We will explore how to enable a single source of truth for workforce data to support responsible analytics, scalable dashboards, and AI‑ready datasets. [Stefanie Blaschke](https://www.linkedin.com/in/stefanie-blaschke/), Head of group people analytics at UNIQA Stefanie is Head of Group People Analytics at UNIQA Insurance Group, specializing in turning complex workforce data into clear, actionable insights. **Scaling Clinical Intelligence with STETHOSCOPE** As healthcare faces a post-pandemic capacity crisis exacerbated by aging demographics, the industry's fragmented data—spanning clinical tables, medical imaging, and ECG recordings—remains its greatest untapped asset. We introduce STETHOSCOPE, an AI-driven framework built on Databricks that unifies these multi-modal streams to alleviate administrative burnout and drastically reduce the risk of misdiagnosis. This session demonstrates why the Databricks Data Intelligence Platform is the definitive backbone for high-stakes healthcare LLMOps, enabling the transition from chaotic data to actionable clinical insights. Through real-world case studies and field experience, we show how agentic architectures transform patient care and operational efficiency.

ABOUT OPENCLAW Forget simple Q&A. We are entering the era of proactive AI. OpenClaw (formerly ClawdBot) is an open source framework that closes the gap between generative AI and real operational execution. AI agents operate inside everyday messengers such as Telegram or WhatsApp and autonomously perform complex business workflows. This event provides a deep dive into the architecture, capabilities, risks, and future implications of agentic systems that will fundamentally reshape how companies operate. WHY OPENCLAW OpenClaw represents a major milestone. For the first time, AI truly acts as a proactive assistant. It does not just respond to commands. It informs you, prepares briefings, and executes tasks autonomously within familiar interfaces such as WhatsApp or Telegram. This marks the transition from passive tools to operational AI agents.
