As part of the tidymodels team, I'm excited to share with you our next project survey. Beside our planned work on postprocessing and supervised feature selection, we would love to hear what the community would find interesting and useful!

I'm at a good spot with the section on "Missing Data" in my new book "Feature Engineering A-Z". Please take a look, would love the feedback 🙏

I'm beyond excited to finally announce my new book "Feature Engineering A-Z" 🎉

The vision for the book is to be a comprehensive collection of feature engineering methods. Describing how they work, when and why you should and shouldn't use it. Code snippets in both R and Python!

I have been working on this project over the last couple of years. Please read it if this interests you! Always looking for feedback!

I was going to do my corp mandated internet security training. Only it needs popups. <sigh> ... I wonder if it needs cross site scripting and third party cookies too?

For day 24 of we look at a fun alternative to dummy variables

Feature hashing is an interesting technique where you create dummy variables, but instead of giving each level its own column, you run the level through a hashing function to determine the column. This means that any number of levels can be put into a fixed number of columns

Kicking off where I show you a {recipes} step I hope you will find useful each and every days for 25 days!

First step we will look at is step_dummy_extract(), this steps pulls out all the levels in a string and counts them like step_dummy() would

With sep or pattern and a bit of regex you can handle any kind of data

I'm back with new and improved color palette discovery with https://emilhvitfeldt.github.io/r-color-palettes/!

Find the perfect palette from {paletteer} with a few clicks. see it in use and find other palettes that look just like it!

Gosh I hope folks in abuse situations had their phones off. All my stuff was on silent and it still was super loud.

Just got my first start-to-finish at-least-all-the-slides-are-there deck for my talk next week! Fondly remembering naive me who thought the slidecrafting would only take infinity ♾️

@Cmastication @grrrck don't worry! there is plenty of time! I haven't started on my last slide deck yet...

@grrrck @Cmastication just add Reveal.shuffle() to a sample of past slides and we are rolling

I just discovered that quarto slides have a "shuffle" mode and now I'm contemplating presenting at posit conf in chaos mode

emilhvitfeldt,
@emilhvitfeldt@fosstodon.org avatar

@grrrck The trick is to have it turn on sometimes! By adding this to your quarto document

&lt;script&gt;  
 window.addEventListener("ready", function() {  
 if (Math.random() &gt; 0.1) {  
 Reveal.shuffle()  
 };  
 });  
&lt;/script&gt;

I did it again! wrote another extension, this time a Revealjs plugin to spruce up code blocks!

Make code blocks look like browser windows, complete will file names and ICONS! many data science icons are already enabled

We are ready with another set of release for {recipes} and the extension packages {textrecipes}, {themis}, and {embed} 🎉

While it isn't reflected in the NEWS files, a lot of work was done over the last couple of months. The work was focused on internal refactoring, improving test coverage, and increased consistency.

With these changes done, I expect many great things in the future!

<rant> packages should run single threaded by default </rant>

@ERDonnachie I'm not in a finger pointing kinda mood, but there are lots of packages that default to all cores, or all - 1 cores
