Abstract:
Uncertainty is measured in many different ways in different fields. The most
popular ways of assessing uncertainty are through variance of a probability
distribution or its information-theoretic entropy. There is however, a very
natural notion of uncertainty of a probability distribution: uncertainty can
be thought of as a "distance to a certain distribution". I will take this notion
and formalize it to show how it leads to measures of uncertainty that have
some interesting properties. The formalism plays with metric and measure-
theoretic properties of the underlying problem. In fact, Shannon entropy is
shown to stem from this analysis, but it is revealed that its metric structure is
trivial. I will then describe how uncertainty evolves in time under the action
of a dynamical system, where no assumptions of linearity or Gaussianity
