System MEMORI automatically detects and recognizes rotated and/or rescaled versions of the objects of a database within digital color images with cluttered background. This task is accomplished by means of a region grouping algorithm guided by heuristic rules, whose parameters concern some geometrical properties and the recognition score of the database objects. This paper focuses on the strate...

Web pages provide valuable knowledge for human comprehension in text, tables, and mathematical notations. However, the extraction and maintenance of structured rules from the Web pages are not easy tasks. To tackle these problems, we adopt the eXtensible Rule Markup Language framework. The RIML (Rule Identification Markup Language) and RSML (Rule Structure Markup Language) are two compliant rep...

The aim of this study was to develop machine learning techniques that would facilitate knowledge acquisition from an expert by taking over the knowledge engineering task of identifying intermediate abstractions. As the expert provided knowledge the system would generalize from this knowledge and use the abstractions it learned in order to reduce the need for later knowledge acquisition. This ge...

Electricity demand response refers to consumer actions that change the utility load profile in a way that reduces costs or improves grid security. The focus of demand response has mainly been on the commercial and big industrial sectors because of the large demand reduction that they can offer to the utility grid operators. Utilities are showing increasing interest in residential demand respons...

We propose a Bayesian grouping approach for recognition and segmentation of large-scale structures representing objects in images. It is based on detection of local image properties, extraction of simple geometrical primitives, and grouping these primitives according to probability rules and prior models. As opposed to the various template matching techniques, our method does not rely on a fixe...

to assess the genetic diversity for morphological and agronomic traits in iranian oriental tobacco germplasm,100 oriental and semi-oriental tobacco genotypes from the urmieh tobacco research center collection were evaluated in the field using a simple square lattice design with two replications. some agronomic traits were measured on five randomly selected plants in each plot. genotypes were cl...

Research into the maintenance of procedural knowledge has focused on the detection of declarative meta-structures within the procedures. An alternative approach is described here based on the ripple-down-rules (RDR) formalism. To the standard RDR rule tree, we add a functions environment hierarchy that stores the implementation of the procedures used in the rules. This functions environment str...

Complex systems arising in a modern society typically have many resources and strategies available for their dynamical evolutions. To explore quantitatively the behaviors of such systems, we propose a class of models to investigate Minority Game (MG) dynamics with multiple strategies. In particular, agents tend to choose the least used strategies based on available local information. A striking...
