But that's not an apples-to-apples comparison, as the artificial neurons of neural networks are just a rough approximation of our neurons. They are also connected in a much simpler way too (nicely divided into layers, where each layer can only pass signals to the very next layer), so it could be that it isn't just a matter of how many parameters you have.

- waffletower 3y agoYou didn't read what I said. Did I need to use a specific fruit metaphor so you would understand that I claimed they weren't directly comparable?
- GTP 3y agoYes, you said that those aren't directly comparable, but your comment seems to imply that you can account for the difference by having more artificial neurons than the number of biological neurons that we have. Sorry if this is not the case.
