Forest is a very important ecosystem and natural resource for living things. Based on forest inventories, government is able to make decisions to converse, improve and manage forests in a sustainable ...
Maximum entropy estimation of values at Mt. Etna: comparison with conventional least squares and maximum likelihood results and correlation with volcanic activity
frequency-magnitude distribution maximim entropy method Mt. Etna
2015/10/8
The variations of the b coefficient in the frequency-magnitude relationship for earthquakes which occurred at Mt. Etna from 01/01/90 to 31/12/92 are analyzed; the completeness threshold for our earthq...
Enriching the Knowledge Sources Used in a Maximum Entropy Part-of-Speech Tagger
Maximum Entropy Part Speech Tagger
2015/6/12
This paper presents results for a maximumentropy-based part of speech tagger, which achieves superior performance principally by enriching the information sources used for tagging. In particular, we g...
Bayesian interpretation of Generalized empirical likelihood by maximum entropy
Bayesian interpretation Generalized empirical likelihood maximum entropy
2012/3/1
We study a parametric estimation problem related to moment condition models. As an alternative to the generalized empirical likelihood (GEL) and the generalized method of moments (GMM), a Bayesian app...
An Efficient Algorithm for Maximum-Entropy Extension of Block-Circulant Covariance Matrices
Efficient Algorithm Maximum-Entropy Extension Block-Circulant Covariance Matrices Optimization and Control
2011/9/5
Abstract: This paper deals with maximum entropy completion of partially specified block-circulant matrices. Since positive definite symmetric circulants happen to be covariance matrices of stationary ...
Maximum entropy distribution of stock price fluctuations
Maximum entropy distribution stock price fluctuations

The principle of absence of arbitrage opportunities allows obtaining the distribution of
stock price fluctuations by maximizing its information entropy. This leads to a physical
description of the u...

Optimal Portfolio Diversification Using Maximum Entropy Principle
Diversification Entropy measure Portfolio selection Shrinkage rule Simulation methods
2011/4/2
Markowitz’s mean-variance (MV) efficient portfolio selection is one of the most widely used approaches in solving portfolio diversification problem. However, contrary to the notion of diversification,...
A Family of Maximum Entropy Densities Matching Call Option Prices
Entropy Information Theory I-Divergence Asset Distribution Option Pricing
2011/3/23
We investigate the position of the Buchen-Kelly density in a family of entropy maximising densities which all match European call option prices for a given maturity observed in the market. Using the L...

2010/11/5
The structure of the ground spaces of quantum systems consisting of local interactions is of fundamental importance to different areas of physics. In this Letter, we present a necessary and sufficient...
Maximum Entropy Distributions Inferred from Option Portfolios on an Asset
Entropy Information Theory I-Divergence Asset Distribution Option Pricing Volatility Smile
2010/10/29
We obtain the Maximum Entropy distribution for an asset from call and digital option prices. A
rigorous mathematical proof of its existence and exponential form is given, which can also be applied to...
Analytical continuation of imaginary axis data using maximum entropy
Analytical continuation imaginary axis data maximum entropy
2010/3/9
We study the maximum entropy (MaxEnt) approach for analytical continuation of spectral data
from imaginary times to real frequencies. The total error is divided in a statistical error, due to
the no...

Quantum models of classical mechanics: maximum entropy packets
Quantum classical mechanics maximum entropy packets
2010/4/7
In a previous paper, a project of constructing quantum models of classical properties has been started. The present paper concludes the project by turning to classical mechanics. The quantum states th...
