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.

**Walk & Talk** Willst du auch mehr Bewegung in dein Leben bringen? Und dich dabei noch gut unterhalten, so dass die Zeit verfliegt? Dann bist du hier genau richtig, denn mir geht es genauso. Alleine ist langweilig und die Zeit vergeht nicht, daher hab ich mir Walk & Talk überlegt. Inspiriert wurde ich durch die Walk & Talk Gruppe in Hamburg, wo ich mehrere Male dabei war als ich in Hamburg lebte. Unterschiedliche Menschen treffen sich einmal in der Woche für einen flotten Spaziergang und unterhalten sich dabei. Ich liebe es neue Menschen kennenzulernen und auch bekannte Gesichter wiederzusehen, dann geh ich ganz nebenbei und das macht auch noch Spaß.😊 **Walk:** Wir brauchen einfach regelmäßige Bewegung und ich weiß selbst, wie schwierig es ist, diese in den Alltag zu integrieren. Deshalb ist dieser Walk genau richtig. Nach diesem Spaziergang fühlst du dich einfach wohl, fit und entspannt. **Talk:** Das Reden kommt ganz von selbst beim Gehen. Du kannst über alles reden, egal, ob privates oder berufliches, alles was sich ergibt ist willkommen. Und wenn du keinen Bock aufs Reden hast, dann gehst du alleine, auch das ist völlig in Ordnung. **Wie das ganze abläuft:** * Die Teilnahme ist völlig kostenlos. * Wo: U6 Spittelau (im Freien), Richtung Donaukanal, Ausgang Josef-Holaubek-Platz, direkt vor dem Fernwärme-Turm (https://maps.app.goo.gl/XwAayz4FQe2EW8WK9) Wenn du mit der U4 kommst, geh bitte zum Hauptgebäude, wo die Züge und die U6 fahren. * Wann: Wir treffen uns dienstags um 13 Uhr, egal, ob bei Regen, Sturm und Kälte oder bestem Sonnenschein – Walk & Talk findet nahezu JEDE Woche statt außer ich bin mal im Urlaub. * Wir starten pünktlich und beginnen mit einer kurzen Vorstellungsrunde. * Wie gehen am Donaukanal entlang von Höhe Spittelau bis zum Schwedenplatz und zurück. * Ca. 7 Kilometer sind wir unterwegs und unterhalten uns dabei mit interessanten Menschen. Dabei kannst du neue Bekanntschaften schließen, dich inspirieren lassen, von Projekten erzählen oder einfach nur smalltalken und die frische Luft genießen. Alles ist erlaubt. * Nach ca. 1,75 Stunden sind wir wieder am Ausgangspunkt zurück. * Bei einer Teilnahme von über 5 Personen gehen wir in Paaren und wechseln diese alle 10 Min. Wenn du aber lieber alleine gehst, ist das auch vollkommen in Ordnung. * Für alle, die einfach mal etwas Neues ausprobieren wollen. **Bist du bereit?** Dann komm mit! **Start bei U6 Spittelau Ausgang Donaukanal** Nochmal: um **PUNKT 13.00 Uhr dort sein**, denn **nach kurzen Vorstellungsrunde gehen wir gleich los. Sei pünktlich, denn die Gruppe wartet nicht.** Du musst nichts vorbereiten oder dich gar anmelden, komm einfach vorbei. Ausreden gibt es nicht. Geh mit und freu dich auf eine tolle neue Erfahrung. **Wer macht es?** Ich bin Marie Meyer-Marktl und Ideengeberin, Host und Organisatorin von Walk & Talk. Ich unterstütze seit 2019 Menschen dabei Freude ins Arbeitsleben zu bekommen und bin Business und Life Coachin. „Strahle, wenn du an deine Arbeit denkst“, ist meine Vision für jedermann und jedefrau. Privat merkte ich, dass ich endlich wieder mehr Bewegung brauche – und das klappt am besten gemeinsam mit anderen Menschen. Sei dabei bei Walk & Talk und bring Bewegung in dein Leben. **Do you speak English? Then welcome to Walk & Talk!** This event is suited for all people who like to connect to other people and like to walk. The beauty of this regular event is that you are in the nature and you walk around 7 kilometers. In the meantime, if you feel for it, you talk, if not, you just walk. You do something for your health, get to know new people and you will feel much better. It’s FREE, all you need to do is to show up this Tuesday at no later than 1 pm at the U6 Spittelau exit to Donaukanal.

Are you interested in improving your presentation skills? Want to become more comfortable speaking in front of people? Do you feel the need to enhance your creativity and connect better with your audience? Here, you'll have the opportunity to practice your presentation skills in a fun and creative environment like never before! This evening, you will have the opportunity to participate at an event called PowerPoint-Karaoke: presenting slides that you've never seen before. There will be random short presentations but also special group presentations created for this event. And if you want to challenge yourself even more then there is the option of grabbing some additional feelings from the challenge box 😊. Even if this sounds daunting, we encourage you to embrace the challenge and experiment in a fun and safe environment where you're allowed to fail! You're also welcome to join regardless of whether you want to present or simply observe. Expect a pressure-free atmosphere that encourages everyone to at least try and tap into their talent, as it's bound to be an enjoyable experience filled with improvisation. *** We'll meet at **Quentin Kaffeebar** in Kaiserstraße 96. We'll be there from 7:00pm onwards and begin with the event at 7:15pm. You'll find us in the back where the beamer is. The event lasts around three hours with a 15-minute break in between. *** We are a group of people who organize monthly Social Adventures, everyone is free to join. This event will be held in English, please respect each other and speak English only. German events will be organized in the future as well. ### 📢 **Stay Updated** Join our Telegram to keep up with all upcoming events: 👉 **t.me/czc_vienna**

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.

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.
