I last posted here about 6 months ago. Here's what I've been working on and/or thinking about. #rstats, #statistics, #ml

package upkeep: we are doing major preventive maintenance on the tidymodels packages ("upkeep week!"). It's rote but very rewarding work. Error messages are 100x better.

I just gave a 20m overview of the #TabPFN deep learning model at R/Pharma.

The slides are at: topepo.github.io/2025-r-pharma/

We've made a blog post about a new major version of the #rstats tune package! Two main changes: parallel processing frameworks and the ability to tune postprocessors.

tune version 2.0.0
A new version of tune brings significant updates for model tuning and parallel processing.

I'm excited to share side::kick(), an experimental open-source coding agent for RStudio built entirely in R. It can interact with your files, communicate with your active #rstats session, and run code.

Check it out: github.com/simonpcouch/...

I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`.

It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.

ML success ≠ Kaggle leaderboard. The real world rewards:
- Clear explanations
- Thoughtful metrics
- Collaboration with domain experts

A 0.01 lift in F1 score won’t save you if no one understands your model.

Announcing a new blog series on LLMs from @veerle.hypebright.nl!

In Part 2, “Talking to LLMs: From Prompt to Response”, we get hands-on with LLM-powered apps. This guide is for #Python & #RStats users who want to go beyond the basics.

In working on an eval for an experimental tidymodels AI assistant, I realized that today's frontier LLMs know much more about #rstats tidymodels than I thought.

www.simonpcouch.com/blog/2025-08...
A ggplot2 bar plot. On the x axis are two LLMs, Claude Sonnet 4 and Gemini Pro 2.5. Both bars are dodged by three configurations: Predictive, Databot, and `run_r_code()` tool. On the y axis is relative performance, ranging from 0 (baseline model) to 100 (best human modelers). The bar heights for Claude Sonnet 4 are all about the same (around 80) and, for Gemini 2.5 Pro, the height for Predictive, an app designed specifically as a tidymodels assistant, is much lower (around 20).

Welp, {chores} by @simonpcouch.com is an immediate install for sure.

Basically it's {usethis} plus llm bundled into RStudio/Positron key encoding.

Excited!!! 🧹🧺
