Wat er echt gebeurt in een AI-agent, en hoe je er zelf mee gaat experimenteren, met praktische tools die uitbreiden wat hij kan.
In this talk, we’ll open the box and explore what it takes to experiment with AI agents, understand how they work, and extend what you can do with them through practical tools.
The session will unpack the building blocks behind agentic workflows and reveal what is really happening “inside the box.” Whether you’re curious about AI agents or eager to start experimenting yourself, you’ll leave with a practical introduction, fresh insights, and plenty of ideas to build on. What’s powering it all? You’ll have to attend to find out.
programma - Marc Buma & Susanne Pieterseback-to-the-future-building-a-rag-powered-vr-time-machineover deze talk
Loop in VR door het Utrecht van 1528 en vraag een gids naar de monumenten om je heen. Hoe de RAG-pipeline erachter antwoordt uit teksten van archeologen, zonder dingen te verzinnen.
Imagine stepping into the streets of Utrecht in the 1500s. Now imagine having an all-knowing guide who can answer any question about the monuments around you.
We built a browser based VR application that gives users a 360-degree historical view of Utrecht on their phone or in a VR headset, where they can ask questions about the monuments around them. The answers are generated using Retrieval Augmented Generation, combining spatial context from the 3D environment with historical texts written by archaeologists.
In this session we will show how we built this time machine using Spring Boot, Ollama, Docling, LangChain4J, React, Typescript, cloud based LLM and LangChainJS. More importantly, we share what we learned while building the RAG pipeline: extracting text from archaeological reports, chunking sources in meaningful ways, improving retrieval quality, preventing hallucinations, and engineering context-aware prompts in the frontend.
After the presentation you can visit Utrecht in 1528 and the following centuries yourself and talk to our guide!
