Hacker News Reader

I'd highlight my comment there on recent progress since that was posted back in 2021: https://www.lesswrong.com/posts/mHqQxwKuzZS69CXX5/whole-brai...

Wow very interesting.

They say the holdup is that they lack a way to read the weights and thresholds of the neurons.

So they have the network structure, but not the weights. It says that there isn’t enough interest in funding research on a method to read the weights either. That’s really surprising. This method could unlock some crazy cool science.

It seems like with the current fire around AI, that making a worm or fly brain function in a simulated environment would be a hot bed of research. I wonder if the research is hot, but private, like at OpenAI, or Neuralink.

They started publishing again this year! They’ve isolated the neural net and published it as a “liquid neural network”. Check it out, it outperforms CNNs for niche tasks with a fraction of the resources.
