Dealing regularly with large datasets, I experienced how to integrate @ApacheArrow and @duckdb into my process with #rstats. I summarized how to use them together, the different format and did a benchmark on size and performance. In English & French: bit.ly/3sEtEyD

Interested in #DeepLearning and #rstats? I played with #Keras for #rstats to solve a binary classification problem, using Kaggle's May 2022 competition. 3 months later, I finally wrote about it and share the code. Details: bit.ly/3zTqNFn Code: bit.ly/3bQJRvR

When hearing for the first time about #processmining, it can be challenging to go beyond the sales pitch to understand how it works. I wrote an introduction post with a very simple example, and with a demo application, using #rstat, #python and #shiny. christophenicault.com/post/i…

I’ve written a textbook on improving your statistical inferences. It consists of the content I teach in workshops, and combines material from my MOOC’s, blog, and published work. It’s a free open educational resource: You can read it here: lakens.github.io/statistical…

If you are starting a new semester with "An Introduction to Statistical Learning" and want to pick up #tidymodels at the same time, then you are in luck✨ I have compiled (mostly complete) labs using tidymodels for all of you to use and teach with emilhvitfeldt.github.io/ISLR… #rstats

An athlete stood out clearly in this #TidyTuesday, so I decided to focus only on the medals won by Trischa Zorn who participated in 7 Paralympic Games, and have some fun drawing! Code: github.com/cnicault/tidytues… #rstats #dataviz #r4ds #ggplot
