Join us for a fun session of improv theatre in English! A great opportunity to meet new people in Utrecht and learn something new with Improv Utrecht. Everyone can partcipate, you don't need any experience in theatre nor fluency in English. **Special topic: Movement & Theatre improv** Movement improvisation is a wonderful basis for all other forms of improvisation. Well before we had language we had movement; there is so much that can be expressed without words. Instead of the games that are used in theater improv, we work mostly with “scores”, or a kind of blueprint to what will happen in a space of time. A kind of a structure. We will do exercises that originate from Viewpoints, physical theater, and other forms of improvisation (including a bit of Contact Improv at times), and moving in/with/through the space, non verbal contact and how we can communicate through our bodies. Anyone can participate, you don’t need any experience in movement or theater nor complete fluency in English. This workshop is without shoes: bring non-slippery socks In this session you will: * Meet fellow international and local players. * Learn the basics of improvisation, a 21st-century skill that is useful in many aspects of life. * Get out of your head. * Enjoy failing. * Play funny and moving theatre games. * Laugh a lot, while surprising yourself and others. Doors open: 19:50-20:00, come in with the others ([SIDE entrance, at the Troelstralaan](https://maps.app.goo.gl/ntLDUqbkDxMHjp7B7)). After 20:01 the door may be closed, but you may find a participant who knows the door code. Workshop: 20:00-22:00 Every Friday except in school holidays Afterwards we have drinks at [O'Leary's](https://maps.app.goo.gl/gL878K1MZf8v5fpm7) pub together ### How to sign up Full details about how to sign up and any other questions you may have can be [found on our website](https://www.improvutrecht.nl/drop-in-workshops/).

**This might be the girls night you didn’t know you needed.** Many women are living in constant “on” mode- always busy, always giving. And somewhere along the way, we forget how good it feels to simply *be together*. This is your invitation to a real **girls night, where you can come as you are.** Every 3 weeks we come together to relax, laugh, connect and support each other — without pressure, without fixing, without performance. **When women gather in a safe and supportive space, something powerful happens.** We uplift each other through shared laughter, honest conversations, and non-judgement presence. Being around other women who get it can make everything feel a little lighter and brighter. It helps us feel less alone, more supported, emotionally stronger - sometimes simply by being in the same room together. Sometimes we talk. Sometimes we listen, Sometimes we laugh - and even sing - until our bellies hurt. You’re free to share what’s on your mind, or simply enjoy the energy of being around other women who get it. There’s no agenda. No judgement. Just genuine connection, joy, and friendships that feel *easy and real.* And often, there’s that quiet thought: *“oh wow, I didn’t know I needed this.”* All I ask is that you come exactly as you are — tired, joyful, quiet, loud, curious, or unsure. Everything is welcome. We meet every 3 weeks - in Utrecht, Amsterdam or Leiden - because connection grows when we keep showing up for each other — not perfectly, just honestly. ✨ Come as you are. ✨ Leave feeling lighter, more connected, and a little more yourself.

SEA (Search Engines Amsterdam) is coming ! This session focuses on **IR evaluation for LLMs and agents**, featuring two speakers: **Arthur Câmara** from **Zeta Alpha** and **Mouly Dewan** from **University of Washington**. **Location:** Science Park 904, Room C3.161 **Date**: February 27 **Zoom link**: [https://uva-live.zoom.us/j/65011610507](https://uva-live.zoom.us/j/65011610507) Details below: **Speaker #1**: **Arthur Câmara** from **Zeta Alpha** **Title**: Evaluating (and automatically improving!) Deep Research agents **Abstract**: Given a user's complex information need, a multi-agent Deep Research system iteratively plans, retrieves, and synthesizes evidence across hundreds of documents to produce a high-quality answer. In our case, an *orchestrator agent* coordinates the process, while parallel *worker agents* execute tasks. Current Deep Research systems, however, often rely on hand-engineered prompts and static architectures, making improvement brittle, expensive, and time-consuming. Similarly, evaluating the quality of these agents is far from trivial, specially when no golden-answer exists. At Zeta Alpha, we are looking into improving **both** of these aspects and in how they may interact. Starting from our LLM-as-a-judge project RAGElo, we are looking into how the LLM-as-a-judge framework, specially using pairwise comparisons, may lead to better agents that can self-play and explore different strategies to produce high-quality Deep Research systems that match or outperform expert-crafted prompts. **Bio:** I’m a Senior Research Engineer working on agentic search and evaluation at Zeta Alpha, an R&D-oriented startup based in Amsterdam. Zeta Alpha develops a sovereign AI platform for enterprise costumers allowing large companies to deploy agents that work on their private data, with a high-quality search backend. Before joining Zeta Alpha, I obtained my PhD from TU Delft, working on Search-as-Learning and Neural IR. **Speaker #2: Mouly Dewan** from **University of Washington** **Title:** LLM-Driven Usefulness Judgment for Web Search Evaluation **Abstract:** Evaluation is fundamental to optimizing search experiences and supporting diverse user intents in Information Retrieval (IR). Traditional search evaluation methods primarily rely on relevance labels, which assess how well retrieved documents match a user's query. However, relevance alone fails to capture a search system’s effectiveness in helping users achieve their search goals, making usefulness a critical evaluation criterion. Recent LLM enabled evaluation works have mostly focused on relevance label generation. In this paper, we explore an alternative approach: LLM-generated usefulness labels which incorporate both implicit and explicit user behavior signals along with relevance to evaluate document usefulness. We introduce Task-aware Rubric-based Usefulness Evaluation (TRUE), a reproducible rubric-driven evaluation framework that leverages iterative sampling and Chain-of-Thought reasoning to model complex search behavior patterns. Our comprehensive study shows that: (i) pre-trained LLMs can generate moderate usefulness labels when provided with rich session-level context; and (ii) LLMs with TRUE framework outperform existing state-of-the-art methods as well as our systematically constructed baseline. We further examine whether LLMs can distinguish between relevance and usefulness, particularly in unique divergence cases between them. Additionally, we conduct an ablation study to identify key features for accurate usefulness label generation, enabling cost-effective evaluation. Overall, this work advances LLM-based evaluation beyond relevance by proposing a reproducible and scalable framework for usefulness judgment, addressing key reproducibility challenges and supporting large-scale LLM-based evaluation. **Bio:** I am Mouly, a 3rd Year PhD student in Information School at the University of Washington, Seattle. My research lies at the intersection of Interactive Information Retrieval (IIR) and Conversational AI, with an emphasis on developing and applying novel evaluation methodologies, particularly leveraging LLMs (LLM4Eval) to improve search, recommendation and proactive conversational information seeking systems. **Counter:** SEA Talks #299 and #300.

Hi, thanks for joining the bootcamp group! Are you planning to come to the next session coming saturday at 11:00? To best adapt sessions to our community, please complete the short questionnaire below: https://forms.cloud.microsoft/Pages/ResponsePage.aspx?id=DQSIkWdsW0yxEjajBLZtrQAAAAAAAAAAAAMAAJ0-AkBUQVdTSUk2SzFGSUxJWlZLVFJDNUI3RTVLVi4u&origin=QRCode

JULIANALAAN 100 park Angerenstein ( Entrance )

Are you ready to blast past the limitations of a jam session? Are you ready to extract every drop of musical creativity? This workshop is for those who are ready to risk putting everything that goes in their brains out there in musical form! After this workshop, you're never going to look at music the same way! More than a jam, the Jam With Humans workshop is a workshop on how to jam. Your teacher Daniel Matias Ferrer will guide you through exercises on musical improvisation and creativity. In a typical workshop, we start by getting to know each other and why we came to the workshop. Then, we warm-up by allowing ourselves to be silly and childishly curious, usually via theatrical exercises. At this point, we replace the verbal component of these exercises by improvised music. We proceed with exercising our skills in coming up with musical ideas, transferring them and listening to the ideas of others, and finish the session with one big jam. **The Jam With Humans Workshops are free to join. A (voluntary) contribution will be requested at the end of the session for helping with production costs (suggested €20).** **🤔FAQ🤔** **Should I bring an instrument?** If you can, please bring your instrument. PARLOUR AMSTERDAM will be equipped with a bass and two guitar amplifiers, a drum set and a PA system with as many vocal microphones as we’d like to use. **I’m a beginner, can I join?** Yes! The workshop is for everyone: we’ll be able to use whatever sounds you can produce plus all your knowledge of music (both from listening and playing) to explore how they can be used creatively in an improvisational setting. The workshop is also a safe space, so don’t be shy in taking risks musically, we have your back! **I’m a professional, should I join?** Absolutely! Given that the workshop is about improvisation and creativity, chances are you’ll be faced with exercises that allow you to explore your instrument in ways you never thought about before. Plus, you’ll be practicing mechanisms of being able to improvise with anyone else, in different instruments and with different musical sensibilities. **How often should I participate?** As often as you want! The workshops are weekly (or fortnightly during summer time) and their syllabus is circular. All workshops are different and it’s recommended that you come to at least three before you make up your mind about them. Otherwise, show up as often as you want: every week, every two weeks, many workshops in a row and then none for a few months… There is only one catch: those who come often will be invited eventually to join The Jam With Humans Orchestra in a separate rehearsal and join our Jam With Humans live shows. Also, those who come really often (regularly for over a year), will be invited to teach workshops themselves, as that’s a fundamental part of the Jam With Humans pedagogical ethos. **Does everyone have to participate, or can I just watch?** Everyone has to participate! If you’re in the room, you’ll have to participate. No observers! Again: we get your back, no worries. Hold our hand and be ready to dive into the world of improvised music, we’ll be there to help you through the journey. **What style do we play?** Whatever you’d like to play. Musical styles, musical genres, those are words which tend to not be imposed to the workshop participants. The goal of the workshop is to harness whatever is your musical language and sensibility to better cooperate with others in an improvisational context. **Is there anything I should do to prepare?** Actively listen to a lot of music. Sit down and think of what went through the musicians/composers heads that lead to what you are listening to. If you’re looking for inspiration, start with one of the three big influences on the Jam With Humans musical improvisation style: John Zorn, Sun Ra, Frank Zappa.

Hello, my dear nature and wine lovers! It’s finally time to reunite, catch up, and kick off a brand-new hiking season filled with beautiful walks, meaningful connections, and memorable experiences. We’re excited to invite you to a special hiking adventure near Nijmegen, combining nature, movement, and Dutch wine culture. We’ll begin the day slowly and gezellig with a traditional cup of coffee at our favorite café in Nijmegen, followed by a relaxed walk through the city. From there, we’ll head into the woods, passing through the charming Philosopher’s Valley, with its swinging hedges, forest paths, and surprisingly hilly landscapes that make this area so special. This hike is all about enjoying nature, good company, and shared moments, with fellow hikers just like you. **Finish in the Wine Village of the Netherlands:** Groesbeek After completing our 14 km hike, we’ll arrive in Groesbeek, officially known as the wine village of the Netherlands. Here, we’ll visit a local wine centre for a guided tour and tasting: Wine tour & tasting: €19.50 per person Vineyard & wine cellar visit Tasting of 3 local wines Non-alcoholic options available Duration: 1.5 hours Optional local food platter: €7.50 per person A bit of background The story of Groesbeek wine began in 2000, when former sports teacher Freek Verhoeven started growing vines as a hobby. Thanks to the rich soil and hilly terrain, his wines quickly gained recognition and even won awards. Today, under new leadership, the winery is known for innovation, including low-alcohol (2%) wines and naturally sulfite-free wines. Groesbeek has since grown into a true wine hub, with vineyards, a professional wine centre, tastings, workshops, and a stunning terrace overlooking the vines, the perfect ending to our hike. **Quick Itinerary** Date: February 28 Meeting Point: Bluf Café, Nijmegen Start Time: 9:30 Distance: 14 km (Nijmegen → Groesbeek) Return: Bus back to Nijmegen **Meetup Fee: €8** **Payment & confirmation:** Please confirm your participation by sending the payment by February 15th to secure your spot; after that, any remaining places will be offered to the waiting list.

**Caller: Frank Buschelmann** **Band: The Rosenthorns** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!
