As far as I can tell the “free energy principle” is just asserting that the brain is approximately Bayesian and is doing some kind of variational inference, right? I’m not sure how revolutionary that is.
(I’m predisposed not to like Friston because his work in fMRI plays fast and loose with the idea of “causality”.)
- atschantz 8y agoThe 'revolutionary' aspect is the suggestion that a single celled organism is also doing variational inference. Or, more accurately, can be described as such.
- eli_gottlieb 8y agoThe trouble is hitting the right "happy medium" between (variational) inference as an explanation of the sensory and motor cortices, and variational inference as a universal theory of everything.
- josepi_ 8y agoMan, I can barely understand any of this. Is there a more ELI5 type explanation anywhere?
