Join us for Symposium! 🌞🌻🌳 In antiquity, a symposium was a gathering of friends who came together to recline around a shared table, where wine and conversation flowed freely into the night. Together, they would choose a topic and take turns speaking, listening, and laughing—guided by the rhythms of drink and dialogue. Inspired by this tradition, our Symposium has no set theme. It's an invitation to come together with other curious minds, to offer up questions or ideas, and to vote together on where to begin. Whether you're hungry for connection or simply seeking space to speak and be heard, you're warmly welcomed to join the conversation. Symposium will meet in parks throughout Prague, embracing the sunshine and pleasant weather while we have it. Bring a blanket or something to sit on. There’s no cost to join, but please bring a snack or drink to share, if you're able. Most of all, bring a curious mind and a willingness to learn from the insight of others. Feel free to bring a friend or two--also, children and friendly dogs are welcome! \*\*\* If the weather doesn't cooperate, we'll try to find an alternate venue—so keep an eye on the event chat or your email for updates. Also, despite the origins of the Symposium, our goal is not necessarily to get drunk and the organizer would encourage you not to come with that sole purpose in mind. :) The first 45 minutes of the event will be dedicated to simply getting to know one another, and we highly encourage you to join for this part. We will then vote whether to continue free conversation, to join together in a single conversation, or to split up into multiple groups. Afterwards, you’re welcome to stay or follow onto any spontaneous activity that unfolds. A note on attendance: If you need to cancel, please do so at least a few days in advance and update your RSVP accordingly. This helps honor the host’s efforts and makes space for others who would like to attend. Repeated last-minute cancellations or no-shows may result in being placed on the waitlist for future events.

This group is for anyone who writes - for any reason. Have a thesis or article you need to write? Trying to finish a novel or an academic paper? This group is for you. We are currently meeting in-person at Locus Workspace. If you have any questions, contact Sonya Lano here or on Facebook or Messenger (https://www.facebook.com/sonya.lano). We start at 9:00, introduce ourselves, and share a few words about what we're working on and what we hope to accomplish during the session. At the end of the session, you can give us a brief recap of how it went. We'll break at noon. The afternoon session starts at 2:00 pm. You're welcome to join both sessions or just one. Please come as close to 9:00 as you can if you come for the morning session. If you come to the afternoon session, we are usually back by about a quarter to 2:00.

**The ABSOLUTE BEST place to be on a Saturday night in Prague! 🤩🍹** Every Saturday, we take over a stunning venue right in the city center and give you **total freedom to mingle at your own pace**. There’s no hand-holding, name tags, or stiff corporate icebreakers here—just a room full of great people skipping the small talk and **sparking real connections**. ✨ During peak hours, the room gets **TOTALLY MAGNETIC** and sometimes even beautifully chaotic. And to be honest, we love it exactly like this! Bar Nomads is all about pure social flow! ⚡🔥 If that’s your vibe, drop the city masks and dive headfirst into our lovely Hoffa madness. You’ll leave feeling energized, deeply connected, and a little bit more like **a true Praguer.** 😎🤙 📍 **Hoffa Bar:** https://maps.app.goo.gl/HRPxX9ruUHphZ4u37

**These are the hottest days of the year. We will meet on the 4th of July at the entrance of the Planetárium Praha ([Královská obora 233, Bubenec, 170 21 Praha 7](https://www.google.de/maps/place/data=!4m2!3m1!1s0x470b94ce6ef24a2d:0x95d62e70e8497a61?sa=X&ved=1t:8290&ictx=111)).** **From 17:00 until 17:15, we will gather in front of the planetarium. After 17:15, we shall then start searching for a nice place under the trees, where we will discuss, eat and drink together until the night…** **If you like to have a philosophical conversation while enjoying the magnificent surroundings of the Stromovka Park, come and join us, the only condition for joining is that you bring something to eat and to drink with you. We will put all the delicious things on a blanket so that we don’t exchange only arguments…** **Even though I normally don’t determine a topic in advance, I would like to ask you this time to make a list of some of your favorite movies. Try to imagine you have to convince another person that these movies are great. What would you say? What makes these movies important for you? What important (philosophical) questions do these movies raise or maybe even answer?**

NOTE THE TIME CHANGE TO 9AM Hi All, Come and join us for social running and a coffee! We meet at the main gate of Vystaviste - tram stop Vystaviste Holesovice. We will run in Stromovka. Usually we run around 50mins and it is up to everyone how many kilometres. We welcome all levels of runner. We can all run together or, if there is more of us, we can split into groups and at the end of the run we all meet close to the starting point to go for a coffee to a nice local coffee place (where they also sell cakes and great chocolate). If the weather is great, we can also just sit in one of the outside coffee placces in Stromovka and enjoy the sun. This is where we meet: http://photos2.meetupstatic.com/photos/event/7/7/3/1/600_447930513.jpeg

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
