For a wide range of entropy measures, easy calculation of equilibria is possible using a principle of Game Theoretical Equilibrium related to Jaynes Maximum Entropy Principle. This follows previous work of the author and relates to Naudts [1], [2], and, partly, Abe and Bagci [3].

An exponentiated Pareto distribution is defined. We then consider maximum likelihood estimator (MLE) of the threshold parameter β with known parameters α and c for the exponentiated Pareto distribution in (2.1) and then obtain the MLE of the tail-probability of the exponentiated Pareto distribution. Finally, we consider MLE of reliability in two independent exponentiated Pareto distributions.

Available online 12 September 2009 We develop a dynamic framework to identify aggregate market fears ahead of a major market crash through the skewness premium of European options. Our methodology is based on measuring the distribution of a skewness premium through a q-Gaussian density and a maximum entropy principle. Our findings indicate that the October 19th, 1987 crash was predictable from ...

This paper describes our system for Shallow Discourse Parsing the CoNLL 2015 Shared Task. We regard this as a classification task and build a cascaded system based on Maximum Entropy to identify the discourse connective, the spans of two arguments and the sense of the discourse connective. We trained the cascaded models with a variety of features such as lexical and syntactic features. We also ...

Two celebrated statistical principlesPrinciple of Maximum Likelihood and Principle of Maximum Entropy are merged establishing a novel estimation scheme for statistical inversion.

We propose here a nev method for retrieving an image from noisy, incomplete data. It is based on an idea incorporating the principle of maximum entropy, a veil known powerful method for image processing. An image is built on the computer by allocating grains to pixels one at a time on the basis of certain deterministic rules as to where each successive grain is placed in image space. The perfor...

Quarkonium at finite temperature Takashi Umeda Brookhaven National Laboratorg, Upton, NY, USA, 11973 Lattice QCD studies on charmonium at finite temperature are presented After a discussion about problems for the Maximum Entropy Method applied to finite temperature lattice QCD, I show several results on charmonium spectral functions. The “wave function” of charmonium is also discussed to study ...

Audio Classification has been investigated for several years. It is one of the key components in audio and video applications. In prior work, the accuracy under complicated condition is not satisfactory enough and the results highly depend on the dataset. In this paper, we present a novel audio classification method based on Maximum Entropy Model. By applying this method on some widely used fea...

Probabilistfc logic has been discussed in a recent paper by N. Nilsson [12]. An ·entailment scheme is proposed which can predict the probability of an event when the probabilities of certain other connected events are known. This scheme involves the use of a maximum entropy method proposed by P. Cheeseman in [3]. The model uses vectors which represent certain possible states of the world. Only ...

A variant of continuous nonequilibrium thermodynamic theory based on the postulate of the scale invariance of the local relation between generalized fluxes and forces is proposed here. This single postulate replaces the assumptions on local equilibrium and on the known relation between thermodynamic fluxes and forces, which are widely used in classical nonequilibrium thermodynamics. It is shown...
