If predictive coding networks were allowed to freely adjust every parameter (both neural activities and weights), they would naturally settle to a zero energy state which would be trivial and not perform any meaningful computation, so in practical implementations and likely in the brain, certain neurons are clamped to specific values

“Let's now put everything together and see how this framework operates as a complete system. If we allow the network to freely adjust every parameter, both neural activities and the weights, it would naturally settle to a zero energy state. However, this solution would be trivial and not perform any meaningful computation. In practical implementations of predictive coding and likely in the brain itself, certain neurons are kind of clamped to specific values.”
