**Tired of endless swiping and superficial speed dating?** You’re not the only one. Most people who join us say the same thing: Dating started to feel rushed, performative, or strangely disconnected. So we built something different. Conscious Connections Club hosts Relational Labs — guided social experiences designed to spark real conversation, emotional depth, and authentic connection. Events now run in **40+ cities across six continents**, bringing together singles who value curiosity, presence, and meaningful interaction. Before joining an event, everyone attends a short alignment call so you can understand the space and decide if it feels like your kind of people. **[Get the Zoom Link →](https://www.consciousconnectionsclub.com/join)** *** **What Happens On The Call** This is a 35-minute alignment call with the founder. On the call you’ll learn: • why this community was created • how Relational Labs are different from speed dating or typical singles events • how we curate intentional spaces across 40+ cities • what actually happens at the events • why many people return again and again Some calls have two people, others twenty or more. You’re welcome to simply listen and get a feel for the space. Many people attend their first event alone — and most leave having met someone they genuinely want to see again. Sometimes it becomes friendship. Sometimes romance. Often it's simply the relief of realizing you're not the only one craving deeper connection. *** **[See If This Is Your Scene →](https://www.consciousconnectionsclub.com/join)** *** **Why We Require This Call** The introduction helps us keep events intentional, respectful, and aligned. It also gives you the chance to decide if the experience feels right for you before joining a live event. No pressure. Just clarity. *** **[Get the Zoom Link →](https://www.consciousconnectionsclub.com/join)**

🗓️ Το **Causal Data Science Meetup της Αθήνας** σας περιμένει στις **19 Μαρτίου, 7:00 μμ** για την 6η συνάντησή του! Καλεσμένος μας ο **[Christos Diou](https://diou.github.io/)**, ο οποίος θα μας μιλήσει για **"Causal Representation Learning: From Pattern Matching to World Models"**. Στην ομιλία αυτή θα δούμε πώς το representation learning μπορεί να εμπλουτιστεί με αιτιώδη δομή. Μέσα από τη θεμελιώδη αρχή των ανεξάρτητων αιτιωδών μηχανισμών και αναφορές σε καθοριστικές εργασίες του πεδίου, θα παρακολουθήσουμε την εξέλιξη του causal representation learning από θεωρητική ιδέα σε ενεργό ερευνητικό ρεύμα που επηρεάζει τη σύγχρονη μηχανική μάθηση. Θα γίνει επίσης μια εισαγωγή στη νέα βιβλιογραφία των *world models*, που στοχεύει σε συστήματα AI ικανά όχι απλώς να προβλέπουν, αλλά να προσομοιώνουν και να συλλογίζονται για το πώς αλλάζει ο κόσμος. Το event θα περιέχει Q&A, networking και τα σχετικά συνοδευτικά. Ραντεβού **στο Impact Hub την Πέμπτη 19 Μαρτίου** στις **7:00 μμ**. Ευχαριστούμε για την υποστήριξη την **Plum**, την **Intelligencia AI** καθώς και το **κέντρο Beyond του Εθνικού Αστεροσκοπείου Αθηνών**. 🚀 Κάνε **RSVP** και μη χάσεις την ευκαιρία να βρεθείς στην 5η συνάντηση της Causal Data Science κοινότητας της Αθήνας! Η πλήρης περιγραφή της ομιλίας στα Αγγλικά: *Modern AI systems have become remarkably good at recognizing patterns, however statistical pattern matching alone is not enough to build systems that are robust, generalizable, or capable of reasoning about cause and effect. In this talk, we explore how representation learning, which aims to equip machines with structured internal models of their inputs, can be enriched with causal structure to produce more reliable and interpretable AI. We will begin with an introduction to representation learning and its limitations, then examine how incorporating the principle of independent causal mechanisms changes the way models represent and respond to their environment. Drawing on landmark papers in the field, we will trace how causal representation learning has evolved from a theoretical idea into a practical framework shaping modern machine learning research. We will also touch on the recently emerging world model literature, which envisions AI systems that go beyond reactive prediction to simulate and reason about how the world changes. The talk concludes with a forward-looking discussion of where this field is headed and what it may mean for the future of reliable, trustworthy AI.*

*The rain-slick streets gleam like silver on a circuit board and holographic signs paint the metroplexes in a river of neon. The city stretches as far as the eye can see, from the toxic coast to the city limits. Despite advances in technology most people continue to live as cogs in a machine, be it physical or virtual.* In **NEON CITY OVERDRIVE**, you are a **cyberpunk**, a desperate individual with valuable skills, willing to put your life on the line in return for a little cash, reputation or leverage. With a lot of effort and a little luck you may survive the dangerous streets and the Grid long enough to fulfill your goals and escape this life of violence and trouble. This is a one-shot. The game will be in **english** (unless everyone can and wants to play in greek), so it is assumed that players are comfortable with the language. Location will be close to Metro station Panormou, and will be shared with confirmed participants a few days before the game. Beginners are always welcome. We foster creativity and inclusivity. Come join us!

Head out to FANGs 2nd annual board game garage sale! **We will have multiple sellers and hundreds of games!** We're selling games from 5pm - 8pm.

Thank you for your continued commitment to providing a fun and welcoming space to veteran, newbie, and rookie gamers in the Columbus area. Parking can be challenging. There is a parking lot behind the neighboring Mexican restaurant that is free and easy to walk from but it's a bit hidden.

Welcome to Casual Boardgames, where we enjoy classic tabletop games and social deduction games while bonding over good food, drinks, and great conversations. 
We started this group to meet new people and make new friends, and bonding over games in a relaxed atmosphere is a great way to do that. We currently meet near route 23 and Polaris Parkway, and this is close to areas like Powell, Lewis Center, Worthington, and parts of Westerville and Columbus. 
Feel free to bring your own games or play one of the many games our members bring. If you are inexperienced, we will help you learn. 
Here are just a few examples of the kind of games we play. 
Tabletop/board games: Splendor, Catan, Azul, Dominion, 7 Wonders… 
Social deduction games: Code Names, Chameleon, Werewords… 
IMPORTANT: 
1. While we love playing a variety of games and competing, we are not just about the games. We interact and talk while playing, and this leads to a lot of laughter and fun. If you just want to compete and focus solely on the game, then this is probably not the group you are looking for. 
2. Many people join groups like this and never (or rarely) show up after weeks or months. If you join and never really come, we will eventually remove you from the group as a courtesy to our members. Why? Because limiting group conversations (on the app) to regular members makes communication and planning much easier. Also, while it may be rare, it protects members from people who join because they are interested in following a person instead of having a real interest in our group. If you get removed, it is just because you haven’t come, and we follow this protocol as a courtesy to our regular game players.
