In this work, we present a straightforward derivation of Kalman filters consistent with active inference via a variational treatment of free energy minimisation in terms of gradient descent.

We link this to popular formulations of perception and action in the cognitive sciences, and show its limitations when, for instance, external forces are not modelled by an agent.

Research on the so-called "free-energy principle'' (FEP) in cognitive neuroscience is becoming increasingly high-profile.
