Wataru Toyokawa

Me at the RIKEN Center for Brain Science, my new place of work!

Me at Haha no Shirataki, a gorgeous waterfall near Mt. Fuji. It's pictured half-frozen, making it outstandingly cool

Happy to announce I started a postdoc with @watarutoyokawa.bsky.social at RIKEN-CBS! 🎉
I'm absolutely thrilled to be here (and not just because it's easy to find great waterfalls)
For this position, I'm broadening my research to include more interactive and naturalistic social learning settings 🧠

It’s today!

How do humans keep inventing tools and technologies that no single person could create alone?

Our new preprint, led by
@anilyaman.bsky.social & @ts-brain.bsky.social
shows that semantic knowledge guides innovation and drives cultural evolution. 🧠📘 arxiv.org/abs/2510.12837

Do any stats nerds have a good reference/examples for how to write about Gaussian Processes models and communicate them to readers? I am estimating spatial autocorrelation of things measured in grids and need some inspiration to guide my writing.
