**💶 Wertschätzungsbeitrag: 10-20 Euro (nach eigenen Möglichkeiten)** **Du möchtest Deine Freundschaften, Partnerschaft & Arbeitsbeziehungen verbessern? Dieser Worskhop kann ein großer Schritt dazu sein.** Beziehungs- und Bindungstypen sind ein weit verbreitetes Modell, um typisches Verhalten in verschiedensten Beziehungen erklären. Warum klammert jemand? Warum Drama? Warum Rückzug? Warum Kälte? Warum Unsicherheit, Nervosität und Ärger? --- und wie sieht eine sichere & gute Beziehung aus (und fühlt sich an). Die Annahme: Ereignisse der frühen Kindheit & der Erziehungsstil unserer Eltern prägen, wie wir als Erwachsene unsere Partnerschaften, Freundschaften & Arbeitsbeziehungen leben. Für manche gut. Für manche weniger gut. Ich setze mich mit den Beziehungstypen auseinander, weil ich glaube, dass sie einen wesentlichen Einfluss auf die Gestaltung von Freundschaften haben (und auf Liebesbeziehungen sowie menschliche Beziehungen jeglicher Art). Dabei habe ich entdeckt, dass ich oft einen vermeidenen Beziehungsstil habe - ich weiche lieber aus, trenne mich oder spreche Probleme nicht an, weil ich wahrscheinlich in meiner Kindheit aus unterschiedlichen Ereignissen gelernt habe... dass bringt eh nichts, ich kann anderen nicht vertrauen, das macht man nicht, meine Bedürfnisse sind nicht wichtig, usw. In der Auseinandersetzung mit den Beziehungs- / Bindungstypen habe ich bemerkt, wie gut es mit tut, mit anderen mich darüber auszutauschen. Weil: * Ich bin nicht allein. * Ich lernen die Gefühle anderer kennen * Ich entwickle ein gutes Gefühl für die anderen Beziehungsstile (nicht nur meinen) * Ich löse das Thema für mich Schritt für Schritt - und werde immer sicher in meinen Bindungen & Beziehungen. In eine Workshop-Beschreibung zu schreiben, dass ich mich oft beim vermeidenden Beziehungsstil entdecke... ist kein Vermeiderverhalten mehr 😊. Halleluja! . **🎁 Das kannst erwarten** Ich lade Dich zu diesem Workshop ein, damit Du einen weiteren Schritt Richtung mehr Leichtigkeit & Ehrlichkeit in Beziehung gehen kannst. Ich werde eine kleine Einführung zu den Bindungsstilen geben - und dann steht der Austausch miteinander im Mittelpunkt: * Was sind Situationen, die mich triggern? * Wie geht es mir dann? * Wie reguliere ich mein Nervensystem? Meine Erfahrung ist: Austausch & Offenheit hilft, mit sich selbst und anderen relaxter zu werden. . Ein Link oder ein Buch zur Vorbereitung findest Du weiter unten. Es wäre gut, wenn Du eines von beiden bereits gelesen hättest oder von anderer Seite Vorwissen zu den Bindungstypen / Beziehungstypen hast. . . **⏰ Die Türen sind offen ab 18:15 Uhr. Komm am besten schon 18.15 Uhr** Mantel aufhängen, Toilette, eine Runde schwatzen und los ... . **❓ Darf ein zweites Mal kommen?** Ja, sehr gern. Ich halte es sogar für sinnvoll, mehrfahr zu kommen, wenn Dir der Workshop gefallen hat: Das Thema vertiefen, die eigenen Beobachtungen aus den letzten Wochen verarbeiten und sich mit neuen & alten Bekannten über das Thema weiter austauschen. 💬 **Agenda** 18:15 Uhr - Doors Open & Ankommen 18:30 Uhr - Start des Workshops * Einführung, Vorstellung * Kleines Kennenlernen * Einführung in das Thema durch mich * Verständnisfragen * Verschiedene Austauschrunden mit Vertiefungsfragen (der größte zeitliche Anteil) * Offene Fragen 21:30 Uhr - Ende . Zwischendurch machen wir eine kleine Pause. . Tausche Dich mit Gleichgesinnten über ein wesentliches Thema Deines Lebens aus. Du kannst immer wählen, mit wem Du Dich in welcher Tiefe unterhalten möchtest. Dein Gegenüber natürlich auch :). Nein heißt nein, Ja heißt Ja 🤗 . **🏠 Der Veranstaltungsraum** * Wir haben einen wunderschönen Raum im Kieztreff in Berlin Mitte (mit sauberen Toiletten!). * nähe Hackescher Markt. Sehr gut mit den Öffis zu erreichen. * Wenn Du vor Ort ankommst, ist alles ausgeschildert. . **🎒 Das bringst Du mit ...** * Etwas zu trinken (z.B. deine Wasserflasche, keinen Alkohol!) * Wenn Du magst: Zettel und Stift. * Du solltest satt sein und vorher gegessen haben * Bargeld für den Wertschätzungsbeitrag (10-20 Euro) . 📋 **Kann ich mich vorbereiten?** Ja! Vielen Menschen sind die Beziehungstypen bekannt. Wenn Du etwas Grundwissen hast, ist das sehr nützlich für den Workshop. Ansonsten empfehle ich diesen Link zu lesen: Link: [Welcher Beziehungstyp bin ich?](https://chrisbloom.de/blog/welcher-beziehungstyp-bin-ich-mit-test/) Dieses Buch ist eine sehr gute Einführung in den Workshop. Der Workshop wird sich daran orientieren: * **[Buch: Warum wir uns immer in den falschen verlieben](https://amzn.to/498A9js) (Werbung, Amazon-Link)** [Werbung: Als Amazon-Partner verdiene ich an qualifizierten Verkäufen.] Das Buch orientiert sich an Liebesbeziehungen, die Erkenntnisse sind meiner Meinung nach aber auf alle menschliche Beziehungen anwendbar. 🚫 **Was ist der Workshop nicht:** Der Workshop ist kein therapeutisches Angebot. Dafür bin ich nicht ausgebildet (bisher noch nicht mal im Selbststudium). Wenn Du aufgrund der Erkenntnisse beim Lesen des Buches, der Links oder der Gespräche auf dem Workshop zum Ergebnis kommst, dass eine Therapie für Dich sinnvoll sein kann, dann wäre das ein richtig guter Schritt. . 💫 **Warum der Workshop gut für Dich ist** * Ich glaube: Niemand ist perfekt. (und gleichzeitig deshalb genau richtig 🙂) * Ich glaube, dass jeder in wenigstens minimaler Form manchmal Arten von unsicheren Bindungsverhalten zeigt * Gleichzeitig wird jeder im Leben mit Menschen zu tun haben, die ein unsicheres Bindungsverhalten zeigen. . Mit sich selbst und anderen reflektiert umgehen zu können, finde ich eine zentrale Fähigkeit im Leben. . Ich finde, dass gute menschliche Beziehungen sind der zentrale Schlüssel zu einem erfüllten Leben sind (das finden laut Jacobsstudie übrigens 85 Prozent der Menschen in Deutschland). . Die Bindungstypen / Bindungsverhalten sind meiner Meinung nach ein zentrales Modell, um gute menschliche Beziehungen führen zu können. . 🧑🏼 **Mehr über mich:** Ich forsche seit 5 Jahren zu guten Freundschaften, wie man diese aufbaut und vertieft.

Liebe Freunde des gesprochenen Wortes, Ob es darum geht, ein Meeting zu leiten oder im Familienkreis einen Toast auszusprechen – diese Situation vor Menschen zu stehen und etwas zu vermitteln kennt so gut wie jeder. Wir lernen gemeinsam, dabei gelassen und souverän zu bleiben, wertvolle Informationen zu transportieren und unser Publikum zu begeistern. **Was macht unseren Club besonders?** Unser "Mut und Rede" Club trägt nicht umsonst seinen Titel: wir pflegen einen wertschätzenden Umgang miteinander, sodass die Hemmschwelle möglichst gering ist, sich selbst auf die Bühne zu trauen. **Wie läuft so ein Clubabend ab?** Es warten vorbereitete Reden auf euch, aber auch ihr habt die Möglichkeit in geschütztem Raum eine spontan improvisierte freie Rede von 1 bis 2 min vor Publikum zu halten. Das klingt vielleicht im ersten Moment etwas abschreckend – aber es ist eine ganz tolle Erfahrung über sich selbst hinauszuwachsen. Und egal was passiert, ihr werdet immer für Euren Mut belohnt. Und es wird auch immer geklatscht. Wir freuen uns, Euch kennenzulernen! Hier findest du die genaue Wegbeschreibung: www.mut-und-rede.de/kontakt#anfahrt Um besser planen zu können freuen wir uns über vorherige Anmeldung: kontakt@mut-und-rede.de https://www.mut-und-rede.de Es findet grundsätzlich jeder Clubabend statt, auch wenn laut meetup nur wenige Teilnehmer zugesagt haben.

Welcome to the PyData Berlin January meetup! We would like to welcome you all starting from 18:30. There will be food and drinks. The talks begin around 19.15 and the doors will close at 18:45. **Make sure to arrive on time!** Please provide your first and last name for the registration because this is required for the venue's entry policy. If you cannot attend, please cancel your spot so others are able to join as the space is limited. **Host**: **Spiced Academy** is excited to welcome you to this month's version of PyData. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* The Lineup for the evening **Talk 1: From Grape Stomping to Gorilla Trekking: AI-Driven Discovery of Novel Interests at GetYourGuide** **Abstract**: UX research shows that discovering new, unexpected and unique things to do in a destination is among the most important needs for travelers. However, surfacing these “hidden gems” at scale is a major challenge for any dynamic marketplace. At GetYourGuide, we tackled this by combining large language models, semantic vector embeddings, and a robust human-in-the-loop process to automatically identify and categorize novel customer interests. Join me as I dive into how we created this AI-driven solution and how we achieved scalable, granular and relevant categorization of our activities. **Description:** How do you help a traveler find something they never knew they wanted? In this talk, I will explore the exciting journey of developing an AI-driven solution to identify novel customer interests at GetYourGuide. With thousands of new activities onboarded weekly, manual categorization became impractical, prompting the need for automation. This talk will walk you through our end-to-end solution: * The problem: the challenges travelers face in discovering relevant and unique experiences, the organizational complexity of this on our platform and its business impact * The AI journey: From raw LLM-based extraction to vector embeddings, clustering, all the way to a robust human-in-the-loop pipeline. I’ll share how we iterated from noisy prototypes to an impactful system, launching 300+ new interests and driving significant engagement and net revenue uplifts * What we learned: The realities of working with LLMs in production-like settings, more specifically hallucinations and issues with relevance, granularity and semantic deduplication. We found out that the line between useful innovation and unwanted noise can be surprisingly fine when using LLM’s. I’ll share practical examples of these challenges and how we addressed them. * Impact and future directions: How we achieved a 10x increase in manual acceptance of AI-suggested interests in just two iterations, and what’s next for AI-driven discovery at GetYourGuide **Bio**: **Morena Bastiaansen** holds a master’s degree in Econometrics from the University of Amsterdam and currently works as a Data Scientist at GetYourGuide in Berlin. She combines her passions for machine learning, language, and travel to build impactful systems for travelers worldwide, with a current focus on personalization in email marketing. Morena is also actively involved in the local tech and ML community. **Talk 2: Deep dive into data streaming security** **Abstract**: Data streaming is powering everything from fraud detection and real-time analytics to patient monitoring and order fulfillment. But as the role of streaming grows, so does the risk - because many streaming platforms, like Apache Kafka, aren't secure by default. In this talk, we’ll take a practical look at data streaming security through the lens of Kafka, one of the most widely adopted streaming platforms in the world. We'll walk through what can go wrong - real examples of exposing 14M patient-doctor messages, or years of real-time delivery info to the internet - and what it takes to do it right. We'll cover the key pillars of securing a streaming system: encryption in transit and at rest, access control, monitoring, and key management. Along the way, we’ll look at the trade-offs like disk encryption vs. end-to-end encryption, what is behind field-level and envelope encryption, and the realities of using customer-managed keys in regulated industries. We'll also explore how streaming security has evolved, how real vulnerabilities (like CVE-2019-12399) highlight the need for patching and monitoring, and what successful multi-layered security looks like in production - from financial institutions to healthcare platforms. If you're building, running, or scaling streaming systems, this talk will help you see the security blind spots and give you concrete steps to protect the data flowing through your pipelines. **Bio**: Olena Kutsenko is a Staff Developer Advocate at Confluent and a recognized expert in data streaming and analytics.

One of the features provided by our Elastic Agent offering is to ingest log files into Elasticsearch so our customers can quickly navigate events in their systems. Reading files and sending data to Elasticsearch sounds simple, right? Not quite. In this talk we're going to dive deep into challenges associated with reading log files and sending them to Elasticsearch. * **18:50 - Talk #2 Flexible Chatbots with Elasticsearch - Integrating Elasticsearch, Confluence, and LLMs** **[Christoph Eder](https://www.linkedin.com/in/christoph-eder-0ab776194/)**, Senior IT Consultant at **[EBCONT](https://www.ebcont.com/en)** **Abstract:** In this talk, we'll show how we developed a flexible enterprise search solution using Elasticsearch — one that not only works in the cloud and with LLMs, but can also run on-premises and be easily combined with different LLMs. * **19:20 - Pizza, drinks and networking** * **20:30 - Wrap up** Invite your friends and join our meetup.

**📅 Week 1 Focus: Kickoff & New Shared Project Theme** We’re starting a new **7-week cycle** with a clear theme: **building one data science project together from start to finish.** 👩‍💻 No experience required Each 7-week cycle focuses on a **small, well-defined part of a larger system**—and over time, these cycles build toward a complete, real-world project (covering data engineering, data science, and deployment). You’re welcome to work on your own project if you prefer, but the shared project gives everyone a common foundation and learning rhythm. 🧠 2026 First Project This cycle’s shared project is an **image-based knowledge extraction system**., including: * Taking photos of book pages or documents * Extracting and cleaning text from images * Structuring that information into something useful (e.g. flashcards, notes, summaries) 📌 By the End of a Full Cycle, You should Have 🎯 A working project in your own GitHub repo 🎯 A small but real portfolio piece you can demo or write about 🎯 Experience going from messy inputs → concrete outcomes Perfection isn’t the goal—finishing something real is. ✨ Who’s Hosting? I’m Lindsey, a senior data scientist working on AI, causal inference, and data products. I’ve built models for fraud detection, uplift modeling, and LLM-based systems—and I care a lot about learning through building, not hype. 📅 When: Saturday, Jan 24 · 9:30–11:30 📍 Where: Torstraße 59, Forward Earth 💻 Bring: Your laptop, an idea—or just curiosity

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)

Open Mic StandUp Comedy. Sign up list goes out at 1:30 p.m. Each performer will get 5 minutes to perform. If you don't want to perform this time around, feel free to come enjoy the mic and relax. If you need to cancel, please change your status to "will not attend."

Join us for another session of our study group as we dive into the fascinating world of Large Language Models (LLMs) using the book **Build a Large Language Model from Scratch** from Manning. In this session, we will finish **Chapter 7: Fine-tuning to follow instructions**. In the last session, we talked about how to prepare the dataset for instruction fine-tuning and in this session we will perform the fine-tuning and evaluate the model afterwards. This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to build a strong foundation together. If you plan to work with the code on your own laptop during the session, try and set-up the environment ahead of time (https://github.com/rasbt/LLMs-from-scratch/tree/main/setup). We will be meeting at the North County Governmental Center this time that is across from the Reston public library.

Ishan will sketch potential roles for pattern discovery, adaptive interfaces guided by human-computer interaction, and approaches to protect patient privacy, using examples drawn from public literature. The focus is on what is feasible now, what remains experimental, and how careful evaluation can guide responsible progress in health informatics. The session closes with open questions and a practical framing to help the community explore this space. An overview of where quantum computing could add value to digital mental health tools today, what is still experimental, and how human-computer interaction and health informatics can guide responsible evaluation. Speaker: Ishan Shivansh Bangroo is a graduate researcher at Penn State University in the College of Information Sciences and Technology. His work sits at the intersection of health informatics and human-computer interaction, with a growing interest in quantum-inspired methods. He studies adaptive clinical interfaces and trustworthy analytics for mental health support, aiming to make digital tools clearer, safer, and easier to use.

HYBRID EVENT, VIRTUAL SPEAKER In this talk, Sean Hoar will explore the transformative journey of AI’s role in modern software engineering, from rapid prototyping (“Vibe Coding”) to strategic AI integration by skilled practitioners. It clarifies the distinctions between AI-assisted, AI-enabled, and practitioner-led approaches, offering insights into how developers can effectively adapt to and harness AI tools. The presentation also highlights recent advancements and practical strategies for leveraging AI in daily workflows and long-term development.

Moving this event to Saturday the 24th because of the weather. **Happy New Year, all!** 🎉 Let’s kick off this year the right way! Join us on Sunday, January 18th, from 1:00 PM to 3:00 PM at Caboose Commons for a *drink ‘til you drop* kind of event… Just kidding of course! 😉 We’ll be drinking and eating responsibly, having some light-hearted conversations, and exploring the spot while getting to know each other better. We’ll chat about everything from where you worship to any cool Christian events you’re interested in. It’s all about connection, fun, and faith! Looking forward to seeing you there!
