Digital Signal Processing

Join us for our next Berlin Collaborative Modelling session — a hands-on workshop where we'll build a Context Map from scratch. Context Maps make the big picture of a system explicit: which bounded contexts exist, how they relate to each other, and where the friction, dependencies, and power dynamics between teams actually live. They help you make better decisions about integration strategies, team ownership, and where to invest in clean boundaries versus where to accept pragmatic compromise. To get there, we'll use Event Storming as our starting point — laying out domain events to discover natural clusters of behavior, then drawing boundaries around them to identify candidate bounded contexts and subdomains. From there, we'll sketch out the relationships between contexts and discuss what patterns like Customer/Supplier, Conformist, or Anti-Corruption Layer look like in practice. What to expect: This is a collaborative, stickies-on-the-wall kind of evening. No laptops needed, no prior DDD experience required — just curiosity about how to make sense of complex systems. We'll work through a shared example domain together, so everyone starts from the same place.

It's all about getting to know new people from your favorite industry. So if you are interested in Motion Design, 2D or 3D Animation, CGI, Illustration or any related field, feel free to join us. Grab a beer in a relaxed atmosphere, have a nice chat about key frames or discuss your next project! Beginner or expert – wir freuen uns auf dich!

Wir bieten allen Interessierten die Möglichkeit, mit Elektronik zu basteln. Workshops und Vorträge zu verschiedenen Themen rund um Elektronik und Software sind willkommen. Von Arduino bis zu komplett selbst entwickelten High-End Schaltungen sind wir für alle kreativen Ideen offen. Wir haben auch Gruppen rund um das Nähen, Programmieren, Retro Computer. Wir treffen uns immer am Dienstag und am Freitag ab 18:00 Uhr. Egal ob Anfänger oder Profi – hier seid Ihr jederzeit Willkommen. Ihr könnt mit anderen fachsimpeln oder auch mit unserer Hilfe Eure ersten elektronischen Gehversuche starten. Wenn zeitgleich in den vorderen Räumen Workshops oder Vorträge stattfinden, kann hinten Werkstattbetrieb stattfinden.

In diesem Kurs beschäftigen wir uns mit verschiedenen Texten aus unterschiedlichen Bereichen. Das können u.a. kurze Geschichten, Gedichte, Zeitungsartikel, Kolumnen oder Videos sein. Immer sind es Themen, die uns gefallen, die wir besonders interessant, wichtig oder manchmal auch richtig schlecht finden. Gemeinsam versuchen wir die Position der Autor*in, den Stil und die Argumentationsstruktur zu verstehen. Dazu diskutieren wir über das, was wir verstehen, welche Meinung wir zu dem Thema haben oder welche Fragen offen bleiben.
Gerne könnt ihr uns auch Themenvorschläge mitbringen oder zuschicken.
Der Kurs richtet sich an interessierte Menschen mit einem B2-Niveau (oder so ähnlich), die Lust haben sich weiter mit der deutschen Sprache zu beschäftigen und ihren Wortschatz zu erweitern.
Die Termine sind sporadisch.

We are excited to feature **Marzieh Fadaee**, who is currently Head of Cohere Labs at **cohere** and will discuss "**Scaling LLMs Across Languages**", lasting approximately 45 minutes. After the talk, seize the opportunity to connect with fellow AI enthusiasts to share ideas and questions while enjoying free drinks and pizza. **Door close by 7.15pm, so please come early! Also, "attend"ing (RSVP) here on Meetup is strictly necessary to be guaranteed entry.** Please note that Meetup has recently been quite keen on promoting its Plus program. However, you are not obligated to purchase it, as both our events and the platform remain free. **Who is this event for?** This event is open to everyone interested in state-of-the-art AI research. We especially design it for students, PhD candidates, academic researchers, and industry professionals with a research focus in machine learning. **Abstract**: Scaling has driven progress in language models, but improvements in peak performance often fail to translate across languages. In this talk, I show how multilingual models expose the limits of scale and highlight the importance of balanced performance. I argue for a shift from optimizing peaks to lifting the floor, through better data, design, and evaluation illustrated through Tiny Aya. **Bio**: Marzieh Fadaee is the Head of Cohere Labs, where she leads research on fundamental problems in artificial intelligence. Her work spans multilingual language models, data-efficient learning, model evaluation, and trustworthy AI, with a focus on building systems that are robust, inclusive, and globally impactful. She co-leads the Aya initiative that brought together over 3,000 collaborators worldwide to create the world's largest multilingual instruction dataset and the development of a series of state-of-the-art multilingual language and vision models. Before joining Cohere Labs, Marzieh was the Research Lead at Zeta Alpha Vector, where she pioneered innovative approaches to knowledge discovery and organization. She holds a PhD from the University of Amsterdam where she conducted foundational research on neural machine translation. Her research has been published in top venues such as NeurIPS, ACL, EMNLP, and ICLR, and she frequently serves as a mentor and advisor in the global AI research community. We are [BLISS](https://bliss.berlin/) e.V., the **AI** **organization** in Berlin that **connects like-minded individuals** who share great interest and passion for the field of machine learning. This summer 2026, we will, again, host an exciting speaker series on site in Berlin, featuring excellent researchers from cohere, ETH Zürich, University of Oxford, HuggingFace, and Stanford University.

Get ready for the **Superbooth Special** May iteration of our monthly meetup! With the Superbooth trade show bringing many audio enthusiasts and professionals to Berlin, we're seizing the opportunity to host a larger gathering. This month, we're moving to a bigger venue, **ForumFactory**, to accommodate up to 200 attendees, with a special focus on networking and community connection. We have an exciting line-up featuring two talks from industry experts: * **Juanpe Bolívar - CTO at BRONZE** (long talk) In this talk we'll learn about persistence (immutable) data-structures and how they can be used to implement novel software architectures that make our software more efficient and responsive, but also easier to understand and modify. We will also how to efficiently persist these data structures across sessions, a novel technique in Immer, unseen in other implementations, that open the door to all new use-cases. We will also briefly show the Bronze Composer, a complex piece audio software that leverages these techniques. * **Tobias Lønnerød Madsen - moonbase.io** (short talk) Commercialising Audio Plugins - Going From Development to Sales and Beyond Following the talks, there will be ample time dedicated to networking. Come meet other local (and visiting!) audio nerds and C/C++ programmers. Network or talk shop – all levels of skill are welcome in the group. **Food & Drinks:** Free pizza will be provided as usual! Please note: for this special event, **drinks will not be complimentary**. However, there will be a bar at the venue where you can purchase beverages. Doors open at 6 pm, talks will start at 6.30 pm.

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!
