The school was founded in the middle of the 15th century by Iizasa Chōisai Ienao at the Katori Shrine (Katori jingū) and has become the origin of numerous other martial arts schools over the course of its almost 600-year history. The training consists of the continuous repetition of fixed sequences of movements (kata) and includes the use of classic Japanese weapons such as the sword (iai-jutsu, battō-jutsu, ken-jutsu, ryōtō-jutsu, kodachi-jutsu), the long staff (bō-jutsu), the lance (naginata-jutsu) and the spear (sō-jutsu), as well as unarmed disciplines, tactics and spiritual aspects. **The Katori Berlin dojo** is the only official shibu of Otake Nobutoshi-shihan’s dojo Shinbukan in Germany and fully dedicated to the transmission and study of one martial tradition: Tenshinshō-den Katori Shintō-ryū. Through these efforts we aim to contribute to the cultural preservation of this martial tradition. The dojo has one officially appointed shidosha. **Our sensei**: Sebastian Graetz has been active in martial arts since 1997. After almost 15 years of taekwondo in Berlin, he started with Katori Shintō-ryū in Asia in 2014. Since then, he has studied in Japan with Ōtake Risuke-shihan and Ōtake Nobutoshi-shihan, and in Vietnam with Malte Stokhof-shihandai. In 2023, he received his Menkyo license and permission to set up a training group in Berlin the following year.

**Authentische Ehrlichkeit - Ein Einführungs-Workshop** **💶 Wertschätzungsbeitrag vor Ort: 10-20 Euro (nach eigenen Möglichkeiten)** . \-\-\-\-\-\-\- . Gute Freundschaften leben von Ehrlichkeit & Vertrauen. . Gute Freunde kennen sich, wie ihre linke Westentasche: ihr Leben, ihre Gefühle, ihre Wünsche, ihre Einstellungen, ihre guten & ihre schlechten Seiten. . Gute Freunde können „Ja“ sagen, wenn es ein „Ja“ ist; und sie können „Nein“ sagen, wenn es ein „Nein“ ist. . Gute Freunde können sich sagen, was sie aneinander mögen, und sie können sich sagen, was sie nicht so toll finden. . **🙂 Ehrlichkeit als Basis guter Beziehungen** Ehrlichkeit ist die Basis, damit Nähe und Verbindung entstehen kann. . Sich hinter Masken und (unbewussten) Lügen zu verstecken steht dieser Verbindung im Weg. . Ich glaube alle Beziehungen im Leben werden vertrauensvoller, wenn man miteinander ehrlich ist: Liebensbeziehungen, Arbeitsbeziehungen, Freundschaften und selbst die Beziehung zur Bedienung im Café. . **🍀 Dieser Abend ist eine Einführung in die Ehrlichkeit.** Du erfährst, * warum „Lügen“ mehr ist als das bewusste Verdrehen von Fakten. * wie Du im Leben mehr von dem bekommst, was Du wirklich willst, weil Du Dich auf Ehrlichkeit einlässt. An diesem Abend werden wir in kleinen Schritten Ehrlichkeit üben, auch in unbequemen Situationen. . Du nimmst praktische Ehrlichkeitsübungen mit, die Du sofort im Alltag und in Deinen Freundschaften umsetzen kannst. **🧡 Zwei Worte über Ehrlichkeit** Ich habe mich lange versteckt, wollte meine schwachen Seiten, meine Ängste, Gefühle & Unzufriedenheiten nicht zeigen – immer mit der Angst, abgelehnt zu werden. . Irgendwann stieß ich auf Radikale Ehrlichkeit und buchte ein Wochenendseminar. Es war so befreiend! . Meine Erfahrungen findest Du hier: [https://abenteuer-freundschaft.de/radikale-ehrlichkeit-erfahrungsbericht](https://abenteuer-freundschaft.de/radikale-ehrlichkeit-erfahrungsbericht) . Danach habe ich das 8-Tages-Retreat gemacht, wo es wirklich ans Eingemachte ging. . Ich habe festgestellt, dass Ehrlichkeit meine Beziehungen zu anderen Menschen deutlich verbessert. . Gleichzeitig fühle ich mich deutlich wohler, weil ich mich nicht mehr verstecke. Ich bekomme meine Probleme gelöst (weil ich darüber spreche) und meine Wünsche erfüllt (weil ich darüber spreche). . Dieser Workshop ist mein Einstiegsbeitrag zu mehr Ehrlichkeit in Beziehungen und Freundschaften. . #### 👱🏼‍♂️ Über mich: * Mein Name ist Georg Preller * Ich bin Betreiber der Seite [www.abenteuer-freundschaft.de](http://www.abenteuer-freundschaft.de) * Ausgebildeter NLP-Lehrtrainer ([DVNLP](https://www.dvnlp.de/)) & Coach * Jahrelang selbstständiger Unternehmensberater * Eigene Vita: Von schüchternen Jungen zum fitten Mann * Mehr über mich: [LinkedIn - Georg Preller](https://www.linkedin.com/in/georg-preller/) . **⏰ Die Türen sind offen ab 18:15 Uhr.** Deinen Mantel aufhängen, WC, eine Runde schwatzen und los geht's... . **❓ Darf ich wiederkommen?** Es gibt nur wenige Veranstaltungen, bei denen man wirklich miteinander ins Gespräch kommt.

Communicative, collaborative and creative drawing sessions. Participants draw a central still-life that the group can create themselves until the music track finishes and then pass it to the person on their left. The drawings change hands 3 to 5 times and the end results are always inspiring. After the collaborative warm-up participants can work individually on printing techniques, Mono -printing, tetra-pack or gelli. -printing. Feel free to try out a process that you are unfamiliar with. There will always be somebody to offer advice if necessary Bring A4 paper, and favourite materials, pencils & brushes. You can also use some studio materials in exchange for a small contribution. A fun but informative approach with consistently creative results!

This talk walks through a production Text2SQL system built on four pillars: semantic models built on customer data, RAG-based semantic search, an agentic verification and correction loop for building the SQL, and an evaluation framework for the entire process. Raw schema information is not enough for text2sql to work. Rather, thorough documentation including business metrics, synonyms, and qualified example queries, are required. We'll cover how to automate this documentation pipeline by mining query logs, generating descriptions with LLMs, and organizing everything into a knowledge graph and vector search index. From there, we'll dive into the agentic flow that takes a user question and iteratively generates, validates, and fixes SQL against a live database. The agentic framework analyses syntax errors and execution results to help it fix the SQL. Participants will leave with practical takeaways on RAG architecture for structured data, agentic retry patterns, and how to think about evaluation for Text2SQL systems in production. **Speaker**: Oren Matar **Bio**: Oren Matar is a principal data scientist and algorithms developer, with a background in social sciences and Bayesian methods. He specializes in NLP and time series forecasting, as well as agentic methods for data retrieval and processing. **Talk 2: Interpreting and Communicating Statistical Models** **Abstract**: Extracting actionable insights from complex statistical models remains a challenge, as raw coefficients are often uninterpretable due to nonlinearity, interactions, or hierarchical structures. This talk introduces a unified framework for model interpretation based on the principles of the Marginal Effects project ([https://marginaleffects.com/](https://marginaleffects.com/)). We move away from internal model parameters toward quantities of interest, such as marginal effects and adjusted predictions that translate statistical output into the "natural language" of the data. We will demonstrate these concepts in Python using the Bambi interpret module, showcasing a seamless workflow for interpreting Bayesian models built on PyMC. The audience will learn how to use the four primary interpretative pillars: Predictions, Comparisons, Slopes, and Marginal Means to compute average marginal effects and visualize conditional relationships. By the end of this session, you will be equipped to turn sophisticated GLMs and multi-level models into clear, rigorous narratives that are easily communicated to stakeholders. **Speaker**: Juan Orduz **Bio**: Juan is a Mathematician (Ph.D. Humboldt Universität zu Berlin) and Principal Data Scientist at PyMC Labs. He is interested in interdisciplinary applications of mathematical methods. In particular, time series analysis, Bayesian methods, and causal inference. **Lightning talks** There will be slots for 2-3 Lightning Talks (3-5 Minutes for each) between the two main talks. Kindly let us know if you would like to present something :) \*\*\* NumFOCUS **Code of Conduct** THE SHORT VERSION Be kind to others. Do not insult or put down others. Behave professionally.

Bring your laptop! **​Abstract: Building "AI scientist"** systems that can reliably generate and evaluate research ideas remains effectively an open problem. While LLMs make hypothesis generation cheap, current systems still struggle to connect evidence across papers, domains, and mechanisms in a structured and reusable way. Evaluation is equally difficult, often relying on opaque “LLM-as-a-judge” methods that are hard to interpret or reproduce. We use Cognee to ingest scientific literature and construct a graph-based representation of papers, claims, and entities with associated vector embeddings. We then use this structure to select and organize the context used for hypothesis generation. Candidate hypotheses are evaluated using explicit graph- and vector-based metrics grounded in the underlying corpus. Initial evaluations by Bayer across targeted biomedical domains demonstrated that graph-based AI memory can reliably support scientific hypothesis generation and validation. **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend.

**History** The [Franklin Park Conservatory](https://www.fpconservatory.org/)’s roots trace back to 1852 when the Franklin County Agricultural Society purchased 88 acres of land to host the Ohio State Fair. After the fair moved to its permanent home, the city of Columbus transformed the grounds into Franklin Park in 1884. This transition shifted the space from a temporary event site to a dedicated public green space for the growing community. The park became a central hub for outdoor recreation and early civic gatherings in the neighborhood. In 1895, the landmark Victorian-style Palm House opened its doors, drawing heavy inspiration from the Glass Palace of the 1893 World’s Columbian Exposition in Chicago. This iron and glass structure became an immediate icon, housing exotic plants that residents would otherwise never see in the Midwest. It remains the oldest part of the facility and serves as a primary link to the conservatory’s 19th-century origins. For decades, it stood as a singular testament to grand horticultural architecture in Central Ohio. A major turning point arrived in 1992 when Columbus hosted AmeriFlora '92, an international horticultural exhibition. This massive event prompted a $16 million renovation and expansion, adding significantly more greenhouse space and the Dorothy M. Davis Showhouse. The festival put the conservatory on the international map and fundamentally changed its scale and ambition. Following the event, the facility transitioned from a city-run park to a private, non-profit organization. In 2003, the conservatory’s identity was further defined through a long-term partnership with world-renowned glass artist Dale Chihuly. After a successful exhibition, the Friends of the Conservatory purchased most of the glass installations, creating the largest permanent collection of Chihuly’s work in a botanical setting. These vibrant glass sculptures are now woven throughout the biomes, blending art with nature. This addition helped cement the conservatory as a premier cultural destination rather than just a botanical garden. Recent years have seen the site expand beyond the glass walls to emphasize community engagement and outdoor education. The 2018 opening of the Scotts Miracle-Gro Foundation Children’s Garden added two acres of interactive landscape designed for hands-on learning. The Scotts Miracle-Gro Company Community Garden Campus also provides local residents with space to grow their own food and learn sustainable practices. Today, the conservatory balances its historic Victorian charm with modern commitments to local ecology and the Columbus community. **Maps of the Conservatory** Here is the [main map](https://www.fpconservatory.org/wp-content/uploads/2025/08/franklin-park-zones-scaled.jpg) of the Conservatory grounds. Here's a [map of the areas](https://www.fpconservatory.org/wp-content/uploads/2026/02/ConstructionMap-2026.jpg) in which the Conservatory has ongoing construction (see below). **Summary** For this event, we'll explore Columbus's highly-rated and very popular Conservatory. As mentioned above, the Conservatory is doing renovations on parts of the facility. These renovations are scheduled to be ongoing until the Fall of next year. Basically, no matter when you go to the Conservatory over the next 18 months, you're going to see some metaphorical orange barrels. So let's just go now. **Tickets and pricing** On the first Sunday of every month, the Conservatory is free for residents of Franklin County and the city of Columbus. You must bring an ID to receive this discount. (Yes, they do check.) Otherwise, tickets are $25.20. Members of the Columbus Zoo (of which I am one) do get a discount on tickets, though I have never actually bought a ticket to the Conservatory (I've always gone on free days). I believe the discount is $4. Parking is always free. If you have additional questions about pricing or whether and for what you qualify, you can reach the Conservatory at 614-715-8000. **Where we'll meet** We will meet just outside the main entrance. I guarantee there's going to be a line. The Conservatory is always popular on free days, and especially in nice weather. **Your GPS is stupid!** Be careful simply typing "Franklin Park Conservatory" in your GPS and going where it tells you. The only way to access the parking lot to the Conservatory is off of Broad Street. Unfortunately, since Google Maps is unable to find its way out of a wet paper bag, it has a tendency to want to take people to a mythical, non-existent Conservatory entrance on Nelson Road. If your GPS does this, just drive to the north side of the Conservatory along Broad Street. Your GPS should then redirect you to the main Conservatory entrance. If your GPS doesn't, then throw your phone away\* and look for the big Conservatory sign on the south side of Broad Street between Nelson Road and Franklin Park West. You also should be able to use the map pin I've provided, below, and it should properly direct you to where you need to drive. \* Don't really do this. **After the event** After stopping to smell the roses, for those that are interested, we'll head to the nearby [Columbus Brewing Company Beer Hall](https://columbusbrewing.com/location/beer-hall/) for [drinks](https://columbusbrewing.com/location/beer-hall/#draft-list) and [lunch](https://columbusbrewing.com/location/beer-hall/#food-menu). The Beer Hall's actual address is [200 Kelton Ave, Columbus, OH 43205](https://www.google.com/maps/place/200+Kelton+Ave,+Columbus,+OH+43205/data=!4m2!3m1!1s0x883889a94ac4acad:0xadb2e60240dbc38b?sa=X&ved=1t:242&ictx=111) (it's literally just on the south side of the Conservatory). Be sure this is where your GPS is taking you when you use it, as the Brewing Company has a taproom on Harrison Avenue that is *not* what you want for this event. We should be at the Beer Hall by 1 if you can't make the Conservatory and just want to join us for drinks.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
