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 time, it’s all about **Agentic Coding**! Whether you are a pure vibecoder building entire apps with natural language or a seasoned dev architecting autonomous agent loops, we want to hear your story. The session is designed to be accessible for newcomers, while still providing depth and practical value for people already working with AI tools. **🕒 Date:** May 19th, 18:00 📍 **Location:** Walls.io Vienna Office **How to get there:** Schönbrunner Strasse 213-215 (close to U4/U6 Längenfeldgasse). Follow the Meetup-Signs! Enter the inner yard through the gas-station, then go up to the 3rd floor! ([https://share.freshvanroot.com/LBYdlr3Z](https://share.freshvanroot.com/LBYdlr3Z)) **Agenda:** TBA **Confirmed Speakers:** **[Edouard Maleix](https://www.linkedin.com/in/edouard-maleix/) \- How AI\-First Dev Teams Build Collective Intelligence** Edouard has been watching teams accumulate agent rules, notes, and feedback controls that never quite add up to a real system. Agents repeat mistakes across sessions, guidance grows without being validated, and what gets built is instructions, not reusable knowledge. His talk is about closing that gap: giving agents their own identity, signed commits, and reasoning linked to every change. When something breaks, the agent captures it, links it to the fix, compares it with lessons from other agents and humans, and feeds what survives back into future work. The goal is making mistakes compound into collective intelligence instead of disappearing into chat history. *** **[Andrew Demczuk](https://www.linkedin.com/in/andrew-demczuk-4038a217/) \- Claws Across the Internet** Andrew is an OpenClaw contributor and AI battle arena builder who has spent his time figuring out what happens when you stop thinking about single agents and start connecting agents with agents. His talk is about AWA: Agents with Agents. When one agent can securely spawn and coordinate subagents across the internet, the force multiplier changes the game entirely. Andrew has stress-tested this in some of the more demanding environments imaginable: competitive AI battle arenas like CodeClash and BitGN, where agents don't just assist, they compete. The talk covers what agentic coordination actually looks like in practice, what secure subagent spawning requires, and what builders can take from the competitive AI space into their own workflows. *** **[David Wischnewski](https://www.linkedin.com/in/david-wischnewski/) \- Vibe Coding vs\. Agentic Engineering** David isn't a developer. He's a builder who uses AI to turn ideas into working tools, workflows, and products. That puts him in an interesting position to compare two distinct ways of working with AI: vibe coding, which is fast and chaotic, and agentic engineering, which starts to become reliable. In this talk, he shares what he's learned building with AI as a non-engineer: where coding agents genuinely help, where they break, and which habits separate a fun demo from something you can actually trust. *** **[Karim El Kaddioui](https://www.linkedin.com/in/karim-elkaddioui/) \- AI Agents in Knowledge Work** Karim is the FP&A Team Lead at Meister, and he's increasingly adding terminal-based AI agents into new and existing workflows. Using Codex, Claude Code, and Claude Cowork, he runs data analysis, builds decks, and manages his task tracker without touching most of the traditional tooling. This talk is a practitioner's view of agentic coding outside of software development: what it actually looks like when a finance professional runs agents in the terminal, where it works well, and what it takes to get there. *** **[Daniel Siegl](https://www.linkedin.com/in/daniel-siegl-b5903a24/) \- The Worktree Multiverse: Where AI Agents Build Software** Daniel Siegl is talking about infrastructure: specifically, the Git primitives that agentic development needs. Worktrees and Git notes have been around for years and mostly ignored. Agentic software engineering makes them essential. When autonomous agents work in parallel, managing state, history, and collaboration across sessions requires more than a single checkout and a commit message. This talk revisits these underused Git concepts and explains why they're suddenly at the center of orchestrating agents that build software. *** We’re excited to share that [SmartGit](http://clicks.meetup.com/ls/click?upn=u001.NY3oBFzZ5LJDG7YcnfSAKsNQOkaxabS6VuUPrlnpHzu8EAPOAc2-2FLyeGuorvSoWce0k5_ObpWV8nzFc9vT8vR4IfdMjR3-2BTWThn0qk33fQ5q-2F29EJaEeD0L-2FPDytPRQrB-2BsUDtKMeGzaIdwbp1FGmo9PE6l49ZAfxZLiwTQ6s9XbkH6uGC6wbt6-2FQCnYmAv3xTHdEc3XPhoZ-2FFXWDSJekk42IULJ-2FF1dAKsajRzahm-2ByuJNbvNnXlHG-2BKddt78zjTwDUCJdBWXmpvSt6VBHSKkXiZ-2BuDokbOEu1-2FP3smPBaMOgImWp0kO-2F3eildobgO6ZZCUNgBPSQ-2BA53lIskQE8Frk49nQGvQYyJW340Lb-2B949yK0O5TjB7rew08D8D4hhaBFwRgpu92uHAjuGR5tkUwhuajsTo6s97LhPUvYBmSmuon5uKncF73Dk1XMPVFbj7uuGbSChlcew2bRo7kmea1bfYMg5o-2BQWm1rzsnbrthIndgl0h2pPhCe9OMftpbr-2BWtOZYZfZiM2Rz1ThF9ttB6B7IUNHVrnBofXkzPZVFJ2tI-2FqkqTDyQuO3Gljd7CW7c1Cq8Hj3NOvEy4HVtxUoi3iCzrpWG-2Fm2p7oRPL0b6BlBI-2FoMX4kBoLoXPIU6WbWhY-2BgvrYNSsmcrqSxnSXUeY4RwFYdWiBhSfj5XUfmcaRR8YLwil8xH-2Bh0LXpulKdQlBMfXb7L32e1OagLarUjPXyj-2BAdDilcZ82siah8dJI9hfg6Xj2R7rhxsEMYuvJCKiWRYfocmxcuvZz2SyKPLThxkH-2Feg-3D-3D) has joined this edition of Vibecoding Vienna as a sponsor, alongside Walls.io and [Fresh van Root](http://clicks.meetup.com/ls/click?upn=u001.NY3oBFzZ5LJDG7YcnfSAKtyU3FvSAroXsYeII059Pq-2FwFUZdDRWR4xSsOgUJwveTzrO2_ObpWV8nzFc9vT8vR4IfdMjR3-2BTWThn0qk33fQ5q-2F29EJaEeD0L-2FPDytPRQrB-2BsUDtKMeGzaIdwbp1FGmo9PE6l49ZAfxZLiwTQ6s9XbkH6uGC6wbt6-2FQCnYmAv3xTHdEc3XPhoZ-2FFXWDSJekk42IULJ-2FF1dAKsajRzahm-2ByuJNbvNnXlHG-2BKddt78zjTwDUCJdBWXmpvSt6VBHSKkXiZ-2BuDokbOEu1-2FP3smPBaMOgImWp0kO-2F3eildobgO6ZZCUNgBPSQ-2BA53lIskQE8Frk49nQGvQYyJW340Lb-2B949yK0O5TjB7rew08D8D4hhaBFwRgpu92uHAjuGR5tkUwhuajsTo6s97LhPUvYBmSmuon5uKncF73Dk1XMPVFbj7uuGbSChlcew2bRo7kmea1bfYMg5o-2BQWm1rzsnbrthIndgl0h2pPhCe9OMftpbr-2BWtOZYZfZiM2Rz1ThF9ttB6B7IUNHVrnBofXkzPZVFJ2tI-2FqkqTDyQuO3Gljd7CW7c1Cq8Hj3NOvEy4HVtxUoi3iCzrpWG-2Fm2p7oRPL0b6BlBI-2FoMX4kBoLoXPIU6WbWhY-2BgvrUUsBkP0lI2pjjLQE1f844pTcm9yC4hHRLy89KKIj9IaVC9OAriE7cvq-2FU3qbtr6mDV-2Fw-2BaSnypyyvgqqKmQisDjktez0D-2BMcOh6GIiLvpGGyj7IMM-2BPiVVneDtzAJGa0NAdjzch-2FcZiwDt2tddQXUw-3D-3D)! **Want to speak at our next event?

**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.

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.

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!

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
