Inferring Entropy Production in Many-Body Systems Using Nonequilibrium Maximum Entropy

Physical Review Letters
We propose a method for inferring entropy production (EP) in high-dimensional stochastic systems, including many-body systems and non-Markovian systems with long memory. Standard techniques for estimating EP become intractable in such systems due to computational and statistical limitations.

Estimating income mobility in Colombia using maximum entropy econometrics.: [PDF]

Income mobility can be viewed as a first-order Markov process, with a matrix of transition probabilities which measure how individuals move from an income status in time t to a new status in time t+1. Direct estimation of transition matrices is difficult,

Parameter estimation for a computable general equilibrium model: a maximum entropy approach [PDF]

We introduce a maximum entropy approach to parameter estimation for computable general equilibrium (CGE) models. The approach applies information theory to estimating a system of nonlinear simultaneous equations. It has a number of advantages.

A maximum entropy approach to the newsvendor problem with partial information [PDF]

In this paper, we consider the newsvendor model under partial information, i.e., where the demand distribution D is partly unknown. We focus on the classical case where the retailer only knows the expectation and variance of D.

Using Entropy Metrics to Analyze Information Processing Within Production Systems: The Role of Organizational Constraints

Logistics
Background: The literature on measuring the complexity of production systems employs the graph and information theory. This study analyzes these systems and their coordination under varying states of control, with a focus on the probability of ...

Models for time-varying moments using maximum entropy applied to a generalized measure of volatility [PDF]

We use an information-theoretic approach to interpret Engle's (1982) and Bollerslev's (1986) GARCH model as a model for the motion in time of the expected conditional second power moment.
