Information, fidelity, and reversibility in photodetection processes

The Reversibility of Interacting Fleming-Viot Processes

Fleming-Viot process is a mathematical model in population genetics. It is a probabilitymeasure-valued process describing the relative frequencies of allelic types in a large population undergoing mutation, selection and genetic drift. The interacting Fleming-Viot process describes the evolution of a collection of Fleming-Viot processes in which those Fleming-Viot processes interact with each o...

A Reversibility Problem for Fleming-viot Processes

Fleming-Viot processes incorporating mutation and selection are considered. It is well-known that if the mutation factor is of uniform type, the process has a reversible stationary distribution, and it has been an open problem to characterize the class of the processes that have reversible stationary distributions. This paper proves that if a Fleming-Viot process has a reversible stationary dis...

Deep Multi-fidelity Gaussian Processes

We develop a novel multi-fidelity framework that goes far beyond the classical AR(1) Co-kriging scheme of Kennedy and O’Hagan (2000). Our method can handle general discontinuous cross-correlations among systems with different levels of fidelity. A combination of multi-fidelity Gaussian Processes (AR(1) Co-kriging) and deep neural networks enables us to construct a method that is immune to disco...

Fidelity in Archaeal Information Processing

A key element during the flow of genetic information in living systems is fidelity. The accuracy of DNA replication influences the genome size as well as the rate of genome evolution. The large amount of energy invested in gene expression implies that fidelity plays a major role in fitness. On the other hand, an increase in fidelity generally coincides with a decrease in velocity. Hence, an imp...
