Improved sparsity support in tidymodels The tidymodels ecosystem now fully supports sparse data as input, output, and in creation.

I'm beyond excited to share with you all that tidymodels now have sparsity support.

We now support sparse data during the whole process, generate data sparsely in recipes steps when your model supports spare data structures. and you don't have to change anything!

Python Developer Tooling Handbook

👋🏻

In the last 10 years, I’ve had a growing interest in making Python development more effective. I’ve learned that a lot of teams don’t make the best use of the tooling available to use.

This has culminated with writing an ebook on developer tooling I’m excited to share with you.
