Deep Reinforcement Learning

# **Das Treffen ist offen für w/m/d Personen.** Die Selbsthilfegruppe Berlin Prenzlauer Berg findet diesmal ausnahmsweise am Sonntag von 16:00 bis 18:00 statt. Zum Thema: **„Ja“ zu mir selbst – Die Kunst, freundlich „Nein“ zu sagen** Fällt es dir manchmal leichter, anderen einen Gefallen zu tun, als auf deine eigenen Grenzen zu achten? Oft sagen wir „Ja“, um niemanden zu enttäuschen – und zahlen am Ende mit unserer eigenen Energie. In unseren zwei Stunden wollen wir gemeinsam herausfinden, warum uns ein „Nein“ oft so schwerfällt und wie wir es lernen können, ohne schlechtes Gewissen Grenzen zu setzen. Wir arbeiten lösungsorientiert, wertschätzend und mit einer Prise Leichtigkeit. Du gehst nicht nur mit neuem Wissen, sondern mit konkreten „Micro-Skills“ für deinen Alltag nach Hause.

Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

Join us for chill **outdoor** beach volley at **Funkhaus Beach**! 🏐 🏐 🏐 ☀️ This event is for everyone who enjoys chill games and is not a *complete* beginner (A1.5+). We play 3v3 (or 4v4) with beach rules. There are no trainers at this event. Register via [the simultaneous event](https://www.meetup.com/berlin-volley/events/) for higher-level 2v2 matches (F1+).

We play in domes that are heated up to at least 15C. It's recommended that you come 10 minutes early so you have time to change and find the fields. If it is your first time, 15 minutes might be even better. You can join whatever court you like and move between courts during the event. We self-organize, so once you finish a game, you can start a rematch, mix with another court, or take a break as you see fit. Upon arrival, join the warmup happening on one of the courts.

Ditch the old book club, where everyone has to read the same book...this is better! It works like this: Bring your own book. Come chat, have some tea or coffee, get to know your neighbors. Then we quietly read together, side by side, for about one hour, each one reading their own book, and afterwards we talk with each other about what we are reading. The usual agenda: - Arrival and introduction (~20 minutes) - ⁠Silent reading (~1 hour) - ⁠Discussion (~30-40 minutes) - ⁠Join us for a bite at a local restaurant afterwards, if you like! You may read in any language, you may read any book. We are a group of international residents of Berlin from many different countries, of all ages, and we converse in English. We welcome you! No registration needed – the event is donation based. All funds support the Offenes Wohnzimmer.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

If you enjoy knitting, crocheting, working with yarn, this is the group for you. Meet new friends, bring your projects, learn from others.
We normally meet a few times a month during the week from 6-8pm. We will occasionally meet on weekends during daytime hours.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
