Just discovered this review and best practice guidelines for AI/ML for Neural Engineering. Some of the best illustrations I've seen of all the different ways cross validiation can (and should not) be done with time series data. Carlson et al (2025). The NERVE-ML Checklist doi.org/10.1088/1741....

I ♥ Quarto... whether for mathy notes, or writing models a collaborator needs in a Word doc, I find it to be such a handy way to combine prose and math. I've been using it since @russpoldrack.org introduced me to it, and happy to share my templates to help others use it github.com/nicholst/Ihe...

For me, this work is a classic @ohbmofficial.bsky.social story: In 2023 I wasn't working with @bttyeo.bsky.social but I overheard him at his poster pointing to some accuracy curves saying "I don't why they have this particular shape". That kicked off the collab that led to these results.
