Natural selection maximizes Fisher information.
In biology, information flows from the environment to the genome by the process of natural selection. However, it has not been clear precisely what sort of information metric properly describes natural selection. Here, I show that Fisher information arises as the intrinsic metric of natural selection and evolutionary dynamics. Maximizing the amount of Fisher information about the environment ca...
متن کاملAdaptive Rescaling Maximizes Information Transmission
Adaptation is a widespread phenomenon in nervous systems, providing flexibility to function under varying external conditions. Here, we relate an adaptive property of a sensory system directly to its function as a carrier of information about input signals. We show that the input/output relation of a sensory system in a dynamic environment changes with the statistical properties of the environm...
متن کاملRelations between Renyi Distance and Fisher Information
In this paper, we first show that Renyi distance between any member of a parametric family and its perturbations, is proportional to its Fisher information. We, then, prove some relations between the Renyi distance of two distributions and the Fisher information of their exponentially twisted family of densities. Finally, we show that the partial ordering of families induced by Renyi dis...
متن کاملNon–Fisher-Information Item Selection Criteria 1 Running head: Non–Fisher-Information Item Selection Criteria Comparison of Non–Fisher-Information Item Selection Criteria in Fixed-Length Computerized Adaptive Testing
The maximized Fisher information (MFI) criterion has been the mainstream of the item selection algorithm in many computerized adaptive test (CAT) programs because of its effectiveness and simplicity. There are still several issues with the MFI criterion, however, that need to be resolved in the field, specifically regarding estimation accuracy at the beginning of CAT administration and item poo...
