Discovering Maximum Entropy Knowledge

This paper seeks to determine a rational agent’s evidential constraints given her beliefs. Rationality is here construed as adherence to a principle of entropy maximisation. I determine the rational agent’s set of probability efunctions compatible with the evidence, \({\mathbb {E}}\) $\mathbb{E}$ , given the maximum entropy function and given some constraints on the shape of \({\mathbb {E}}\) $\mathbb{E}$ . I also consider agents employing a centre of mass approach to form their beliefs rather than entropy maximisation.
