A new trend in the field of pattern matching is to design indexing data structures which take space very close to that required by the indexed text (in entropy-compressed form) and also simultaneously achieve good query performance. Two popular indexes, namely the FM-index [Ferragina and Manzini, 2005] and the CSA [Grossi and Vitter 2005], achieve this goal by exploiting the Burrows-Wheeler tra...

For the learning of Classification Tree, many researchers have used different splitting criteria, in which most commonly impurity-based criteria are: Gini index, Entropy function and Exponent-based index. By comparing Misclassification rates, none of the splitting criterion can be declared as providing best results in every situation. In this study, a new Mean Deviation based index has been pro...

Energy efficiency evaluation of industrial park customers is carried out to help develop optimization strategies and improve the energy level. The indexes are proposed based on pressure-state-response (PSR) model redundant selected by combining principal component analysis (PCA) correlation analysis. Thus dynamic index system constructed. weight calculated entropy method (EWM). An improved Grey...

In this article, we discuss the relationships between thermodynamic quantities and the spatial pattern in a reaction-diffusion model based on the reversible Gray-Scott model. This model is introduced for calculation of the entropy production in a reaction-diffusion system. First, we show the relationship between entropy production and pattern formation, and suggest that the entropy production c...

Based on Shannon’s theory, joint entropy is a statistical mean of information content and could be employed to evaluate image information. However, the computation complexity of joint entropy affects its applications in remote sensing. In this paper, a method with an index data structure to solve this problem is introduced, and in comparison with other methods, joint entropy calculated by the n...

We study a measure entropy for finitely generated free group actions called f-invariant entropy. The f-invariant entropy was developed by L. Bowen and is essentially a special case of his measure entropy theory for actions of sofic groups. In this paper we relate the f-invariant entropy of a finitely generated free group action to the f-invariant entropy of the restricted action of a subgroup. ...
