Unformatted text preview: Res, MSci, MSc). Nick Jones Inference, Control and Driving of Natural Systems The motivation for the course: Inference and Driving Living systems are out of equilibrium and, as such, must be driven.
These systems must thus have a supply of energy. One can think
of this as a setting with two statistical models: a model generating
the world and the organism’s approximation to relevant parts of its
world. The organism can make a more accurate model of the world
but this will have a corresponding energetic cost. If the organism
can construct a suﬃciently accurate representation of the world
then this can be exploited to help it ﬁnd energy to drive itself.
There is thus a very natural relationship between inference about
the world and driving of natural systems. Nick Jones Inference, Control and Driving of Natural Systems The motivation for the course: Inference and Control It is often appropriate to think of the model describing the world
having dynamics in its parameters: this means that the organism
cannot make a static statistical model for the world but ideally
controls that representation: e.g. by appropriately weighting its
past information. As such we need to think of control and
