LLMs in R
**Can R tame the LLM chaos? Let's find out. 🤖**
Two talks. Two live demos. One evening that might change how you think about LLMs in R.
Refreshments and networking from 18h00.
**Agenda**
\~\~\~\~\~\~\~\~\~\~\~\~
\* 16h30 – 16h45 \| Welcome and News \- Handre Williams & Luis de Sousa
\* 16h45 – 17h20 \| Handre Williams: **R as the orchestration + statistical validation layer for LLMs**
LLMs are powerful but unreliable. R is rigorous but underestimated. This talk explores what happens when you combine the two — using R as the orchestration backbone and statistical validation layer for LLM workflows. Handre will show practical patterns for calling, chaining, and stress-testing LLMs from R, and how classical statistical tools can keep your models honest in production. Includes a live demo.
\* 17h20 – 17h55 \| Luis de Sousa: **RAG (Retrieval-Augmented Generation) in R**
LLMs hallucinate. The fix? Give them better memory. This talk dives into Retrieval-Augmented Generation (RAG) in R — combining DuckDB's vector search capabilities with R's data ecosystem to ground LLMs in domain-specific knowledge. Luis will show how to build a RAG pipeline from scratch, turning your own data into a knowledge base that makes LLMs actually useful in practice. Includes a live demo.
\* 17h55 – 18h00 \| Wrap up\, questions & close
\* 18h00 \| Refreshments & networking — continue the conversation in person

Underwater Hockey (open to new players!)
New players are always welcome to come try it out!
What you need:
A bathing suit. Preferably something light and tight.
We have extra gear for new players. But if you have your own pair of flippers, a snorkeling mask, and a snorkel then bring them along.
Please bring this signed and completed form to practice:

Unless you are already a member of USOA:
https://www.underwater-society.org/page/show/4284471-usoa-registration
To find us:
You can tell the front desk that you are here for underwater hockey and they will let you in for free. You can ask them for help finding the pool.
If no one is at the front desk just walk past it and there will be a set of stairs on the left. Take the stairs and take a right at the bottom of the stairs. The men's and women's locker rooms are straight ahead, and you will need to go through them to access the pool deck. Once you are out on the pool deck you will be exactly where we practice.
Agenda:
First 15 minutes: Arrival at the pool, getting gear from the shared gear bin, dividing into two teams, getting gear on.
Minutes 15-30: Getting in the water, teaching any new players the basics
Minutes 20-70: Scrimmage/practice.
Minutes 70-75: Putting away club gear, putting the lane lines back in place, clearing the pool deck.
(optional) afterwards: Go to a local restaurant for food, drinks, and socializing.
