Updating Prediction Errors in Gradient Ascent (Friston's Free-energy)
Background
In Rafal Bogacz's tutorial on the free-energy framework for modelling perception and learning, section 2.3 we have:
$$\dot{\phi} = \frac{\partial F}{\partial\phi} = \varepsilon_u g'(\phi) …

Updating Prediction Errors in Gradient Ascent (Friston's Free-energy)
OK, I've worked it out. Here's the most trivial example I could think of.
$$ I = \frac{V}{R}$$
which can be rearranged:
$$ IR = V$$
So in:
$$ \dot{I} = V - IR$$
$V$ stands for the the actual vol …
