I'm worried about outsourcing to a machine something that's part of our common endeavour to figure out the world. It's not enough that stuff is figured out, it's about **us** figuring it out! I don't remember phone numbers anymore – I outsourced that to my phone. I don't want that for my science.

Very nice thread, but can't get on board with taking all the panels to external software just for the panel labels and layout 🙅
I always use subplot_mosaic (Tutorial from matplotlib docs: tinyurl.com/3efsadeb) and add the panel labels with fig.text(), no third-party software needed!

New #NeuroAI preprint on #ContinualLearning!
Continual learning methods struggle in mostly unsupervised environments with sparse labels (e.g. parents telling their child the object is an 'apple').
We propose that in the cortex, predictive coding of high-level top-down modulations solves this! (1/6)
