Hi Deep Learners, We are happy to announce our next Vienna Deep Learning Meetup on **May 19** at Bosch. Our topics this time are: Improved Optimizers for Deep Learning and Automatic Speech Recognition in Air Traffic Management. \*\*\* **Agenda:** * 18:15 Arrival * 18:30 **Introduction** by the meetup organizers * **Welcome** by the host: Bosch * 18:45 **Talk 1:** **Momentum, Preconditioning, and Beyond: Practical Advances in Optimization** by Ionut-Vlad Modoranu (*ISTA*) * 19:30 **Announcements** * **Networking Break** * 20:00 **Talk 2:** **Cleared for Takeoff: Automatic Speech Recognition in Air Traffic Management** by Christian Sobtzick & Sahebeh Dadboud *(Frequentis)* * 20:45 **Networking** * \~21:30 **Wrap up & End** \*\*\* **Talk Details:** \-\-\-\-\-\-\-\-\-\-\-\-\-\- **Talk 1:** **Momentum, Preconditioning, and Beyond: Practical Advances in Optimization** Modern Deep Learning optimization is largely dominated by first-order methods such as Adam, yet their limitations in memory usage, scalability, and curvature awareness motivate the search for improved alternatives. This talk provides a practical perspective on optimization, starting from the roles of momentum and preconditioning and extending to recent advances that go beyond standard adaptive methods. We present techniques that improve optimization along three key axes: memory, structure, and computational efficiency. In particular, we introduce MicroAdam, a memory-efficient variant of Adam based on compressed optimizer states; Trion, a low-rank method that replaces costly SVD/QR projections with efficient, rank-independent alternatives; and DASH, a GPU-efficient implementation of Shampoo that accelerates second-order preconditioning via improved parallelization and fast matrix inverse root approximations. Together, these methods illustrate how careful algorithmic and systems-level design can overcome the practical limitations of existing optimizers, offering a path toward scalable, memory-efficient, and high-performance training beyond Adam. **About the speaker:** Ionut-Vlad Modoranu is a PhD student at the Institute of Science and Technology Austria (ISTA), specializing in efficient optimization for Deep Learning. His research focuses on reducing the memory usage and computational cost while maintaining the performance, including the development of practical optimizers for large-scale models, with publications at top tier international conferences. **Talk 2:** **Cleared for Takeoff: Automatic Speech Recognition in Air Traffic Management** Automatic Speech Recognition (ASR) has made tremendous progress in recent years. However, its deployment in safety‑critical operational environments poses a fundamentally different set of challenges compared to demonstration systems or research prototypes. In this talk, we present how speech‑to‑text models are used in a real Air Traffic Management (ATM) product at Frequentis. We walk through the end‑to‑end lifecycle of an ASR system: how training data is collected and curated, how models are selected and evaluated, and what it takes to deploy and operate them reliably for customers in a regulated, safety‑critical domain. Beyond the models themselves, we discuss practical challenges from bringing ASR from research into production, where reliability and trust matter as much as accuracy. **About the Speakers:** Sahebeh (Saba) Dadboud is an Expert Data Scientist at the Frequentis AI Competence Centre. With over eight years of experience in the tech industry, she specializes in bridging Deep Learning, MLOps, and product development to build trustworthy AI for safety-critical systems. At Frequentis, she plays a pivotal role in driving company-wide AI initiatives, supporting the adoption of advanced technologies in domains where reliability, safety, and strict regulatory constraints are absolutely critical. She holds a Master’s degree in Computational Science from the University of Vienna. Christian Sobtzick is Audio Expert at Frequentis, leading the HET Audio Competence Centre. He is responsible for improving audio quality across all Frequentis voice communication products, drawing on more than 15 years of professional experience. In addition, he supports product development related to automatic speech recognition and contributes to research projects, such as the FFG “Next Generation Safety” project, which aimed to enable AI‑based automation in Air Traffic Management. His background is the field of acoustics, including electroacoustic transducers, acoustic measurements, and signal processing. He holds an MSc in Electrical Engineering and Audio Engineering from Graz University of Technology and the University of Music and Performing Arts Graz. We are looking forward to welcoming you at our next meetup. Your VDLM organizer team.

This is a structured coworking session for people who want to follow through and get it done. 👉 **New here? You can join for just 2 hours to try it out.** 👉 Stay longer if you want to go deeper. To join, please register here (takes 1–2 minutes): [https://nocrastination.space/](https://nocrastination.space/) **We like a touch of mystery!** **The exact location will be sent to you by email 24 hours before the session. Please make sure to register in advance.** **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” **How long should I join?** You don’t need to commit to the full session. **Option 1: Try it (2 hours, 1:00 PM – 3:00 PM)** Perfect if it’s your first time or you want a light commitment **Option 2: Go deep (4 hours, 1:00 PM – 5:00 PM)** Stay for the full session and build real momentum **Time and location** 🕐 **Every Tuesday, 1:00 PM – 5:00 PM** 💻 **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! **How it works** * **13:00–13:15 → Arrival + Soft intro + Set your task** * **13:15 - 14:45 → Deep focus session 1** * **14:45 - 15:00 → 15’ Break** * **15:00 - 16:30 → Deep focus session 2** * **16:45 onwards → Networking** * 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.

Things to know before playing: Ladies and Gentlemen, boys and girls; We play Tuesday Night Football (outdoor only) .

Claude MAX Plan 20x for 2 months 2. DJI Mini 4K Drone 3. Flipper Zero **First talk**: **"Making significant software architecture decisions"** by Bert Jan Schrijver (OpenValue) Software architecture represents the significant design decisions that shape a system, where significant is measured by the cost of change. At its core, architectural decision-making is about balancing trade-offs to align technical solutions with broader requirements. But how do you approach a trade-off analysis? How do you choose between different solutions, frameworks, tools, languages, or cloud providers? Which factors should guide your decisions beyond just technical fit? And how do you make sure you’re not overlooking non-technical aspects like team expertise, long-term supportability, and hiring feasibility? In this session, he’ll share a structured approach to making informed, high-impact architecture decisions. We’ll break down technical, organizational, financial and other trade-offs and explore how to evaluate and balance competing concerns. You’ll walk away with practical strategies to make better architectural decisions in real-world projects. **About Bert Jan** Bert Jan is CTO at OpenValue and focuses on Java, AI, software architecture, Continuous Delivery and DevOps. Bert Jan is a Java Champion, JavaOne Rock Star speaker, Duke's Choice Award winner and leads NLJUG, the Dutch Java User Group. He loves to share his experience by speaking at conferences, writing for the Dutch Java magazine and helping out Devoxx4Kids with teaching kids how to code. **Second talk**: **"Device Management the DevOps Way"** by Erik Auer and Dimitrij Klesev (Whizus) In today’s hybrid work environment, traditional device management is often manual and opaque. This talk presents a DevOps approach to MDM using Infrastructure as Code and automation for speed, transparency, and GDPR compliance. We’ll show how Terraform defines device configurations and policies as code, while GitHub Workflows automate the full lifecycle — from validation and testing through approval to deployment. Emphasis is placed on a solid approval process where changes are reviewed via Terraform plans, with apply triggered only after the full pipeline and approvals. Learn practical patterns to make device management faster, safer, and fully auditable — turning MDM into a reliable, governed platform capability. **About Dimitrij and Erik** Dimi is Tech Lead at WhizUs with several years of experience working in the Kubernetes ecosystem and the Cloud Native domain. Erik Auer has been managing WhizUs, a company specializing in cloud-native technologies, for many years.

But they all share the same problem: a second source of truth that you maintain by hand. In this talk, I'll share how I built angular-typed-router, a drop-in replacement that infers every valid path directly from your route configuration. You'll see the developer experience in action — full autocomplete, compile-time validation — and learn how interface augmentation, template literal types, and recursive conditionals make it work at zero runtime cost. **\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-❤️🤝❤️ Sponsors ❤️🤝❤️ \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-** **PushBased** PushBased is a close-knit group of IT experts offering their knowledge and services in #Angular #RxJS #NestJS #JavaScript #TypeScript #webperf #Nx and more.

Flipper Zero **First talk**: **"Making significant software architecture decisions"** by Bert Jan Schrijver (OpenValue) Software architecture represents the significant design decisions that shape a system, where significant is measured by the cost of change. At its core, architectural decision-making is about balancing trade-offs to align technical solutions with broader requirements. But how do you approach a trade-off analysis? How do you choose between different solutions, frameworks, tools, languages, or cloud providers? Which factors should guide your decisions beyond just technical fit? And how do you make sure you’re not overlooking non-technical aspects like team expertise, long-term supportability, and hiring feasibility? In this session, he’ll share a structured approach to making informed, high-impact architecture decisions. We’ll break down technical, organizational, financial and other trade-offs and explore how to evaluate and balance competing concerns. You’ll walk away with practical strategies to make better architectural decisions in real-world projects. **About Bert Jan** Bert Jan is CTO at OpenValue and focuses on Java, AI, software architecture, Continuous Delivery and DevOps. Bert Jan is a Java Champion, JavaOne Rock Star speaker, Duke's Choice Award winner and leads NLJUG, the Dutch Java User Group. He loves to share his experience by speaking at conferences, writing for the Dutch Java magazine and helping out Devoxx4Kids with teaching kids how to code. **Second talk**: **"Device Management the DevOps Way"** by Erik Auer and Dimitrij Klesev (Whizus) In today’s hybrid work environment, traditional device management is often manual and opaque. This talk presents a DevOps approach to MDM using Infrastructure as Code and automation for speed, transparency, and GDPR compliance. We’ll show how Terraform defines device configurations and policies as code, while GitHub Workflows automate the full lifecycle — from validation and testing through approval to deployment. Emphasis is placed on a solid approval process where changes are reviewed via Terraform plans, with apply triggered only after the full pipeline and approvals. Learn practical patterns to make device management faster, safer, and fully auditable — turning MDM into a reliable, governed platform capability. **About Dimitrij and Erik** Dimi is Tech Lead at WhizUs with several years of experience working in the Kubernetes ecosystem and the Cloud Native domain.

We’ve partnered with our friends from Angular Vienna to bring you an amazing evening of talks, networking, and spring energy! **Angular & MRDS** Angular is an enterprise-grade framework for building modular frontends. It seamlessly integrates with the complex communication patterns and asynchronous data streams typical of modern distributed and reactive architectures. Some of you may remember our past event about a **Micro Frontend Plugin System** built with Angular. If you are curious to hear what insights have emerged since then, this is the perfect opportunity to follow up! **RSVP** Please make sure to **RSVP on the [Angular Vienna](https://www.meetup.com/angular-vienna/events/314162066) page** to secure your spot! **The Highlights** 🗣️ Expert speakers 🎓 Knowledge sharing on the latest in Angular 🎫 Raffles with cool prizes 👥 Meet old and new friends from the community 🍻 Free drinks 🍕 Free food 🎉 Open-end networking ✔️ Just RSVP! **Location:** LEAN-Coders, Hainburger Straße 33 **Agenda:** 18:00 – Warm-up 18:15 – Meetup Intro 18:30 – Dominic Bachmann 19:15 – Pizza Break (30 mins) 19:45 – Robert Maier-Silldorff 20:30 – Break (15 mins) 20:45 – Raffle 21:00 - Outro & Open-End **\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 🗣️🗣️🗣️ Talks 🗣️🗣️🗣️ \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-** **Robert Maier\-Silldorff \- iteratec \| [LinkedIn](https://www.linkedin.com/in/robert-maier-silldorff-71464ab2/)** **Microfrontend-Plugin-System: Architecture, Challenges, and Lessons Learned** This talk shares the story behind a microfrontend-based plugin system we built for a large enterprise customer. I’ll cover why we chose a plugin architecture, how the system is structured, key challenges we faced and how the solution has evolved over time—ending with lessons learned for building extensible frontend platforms. **Dominic Bachmann \- Vontobel \| [LinkedIn](https://www.linkedin.com/in/dominic-bachmann-645267319/)** **From Typos to Type Safety — Building a Typed Router for Angular** Route enums, path constant objects, flat route trees to avoid nesting complexity — Angular developers have invented all kinds of workarounds to bring some safety to navigation. But they all share the same problem: a second source of truth that you maintain by hand. In this talk, I'll share how I built angular-typed-router, a drop-in replacement that infers every valid path directly from your route configuration. You'll see the developer experience in action — full autocomplete, compile-time validation — and learn how interface augmentation, template literal types, and recursive conditionals make it work at zero runtime cost. **\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-❤️🤝❤️ Sponsors ❤️🤝❤️ \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-** **PushBased** PushBased is a close-knit group of IT experts offering their knowledge and services in #Angular #RxJS #NestJS #JavaScript #TypeScript #webperf #Nx and more.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
