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.

Let’s go to all nighter Speedy J at Club Basis

Tijdens het Vierdevrijdag programma zal er kennis gedeeld worden over diverse tech onderwerpen. Heb je zelf een onderwerp over Bitcoin, neem dan contact op en we zetten deze op het programma. Het doel van deze meet-up is vooral om andere (toekomstige) bitcoiners te ontmoeten. Je bent welkom vanaf 19.00 en duurt zolang er mensen zijn (maar uiterlijk tot 22.00). Mocht je om 17.30 mee willen eten, geef dat dan aan op Telegram of Signal. Meer info over Vierdevrijdag is beschikbaar via https://wondersofwork.nl/agenda/vierdevrijdag-voorheen-tech-tuesday-27-02/

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.
