decision-tree algorithms provide one of the most popular methodologies for symbolic knowledge acquisition. the resulting knowledge, a symbolic decision tree along with a simple inference mechanism, has been praised for comprehensibility. the most comprehensible decision trees have been designed for perfect symbolic data. classical crisp decision trees (dt) are widely applied to classification t...

The study aimed to examine the developmental trajectories of non-symbolic and symbolic addition capacities in children and the mapping ability between these two. We assessed 106 4- to 7-year-old children and found that 4-year-olds were able to do non-symbolic addition but not symbolic addition. Five-year-olds and older were able to do symbolic addition and their performance in symbolic addition...

Symbolic and non-symbolic number representations are thought to share common neural substrates. However, recent studies have shown that the two numerical systems are more distinct than previously thought. These disparate findings may be explained by the use of sequential presentations of symbolic and non-symbolic quantities, the use of magnitude-reliant tasks, or the use of limited number range...

This study examines the visual aesthetic function of English signs in line with ethnographic approaches as a means of achieving various symbolic and communicative implications in the linguistic landscape (LL) of Jordan. Having coded the data in 6 urban streets of the major Jordanian cities, the social semiotic analysis centers on the visual layout of signs based on the typographical features of...

Since the Sassanid era, many reliefs and seals have left and by reviewing their designs, the mythical and religious attitudes of those people can be understood. The purpose of this article is to decode and interpret the symbolic paintings and to review and study the myths, concepts, and religious rituals of this period. The question is that what the divine and human origin of the symbolic paint...

Following the results of cite{Med}, regarding the Aluthge transform of polynomial matrices, the symbolic computation of the Duggal transform of a polynomial matrix $A$ is developed in this paper, using the polar decomposition and the singular value decomposition of $A$. Thereat, the polynomial singular value decomposition method is utilized, which is an iterative algorithm with numerical charac...

During recent decades social theory has struggled with the attempt to overcome both subjectivist and structuralist conceptions. In this effort, actors have been understood to construct social reality through their practices. Thus, social practices are socially constructed at the same time. Neither subjects nor objects existed prior to this work of construction; the nature of reality is therefor...

Symbolic integration deals with the evaluation of integrals in closed form. We present an overview of Risch’s algorithm including recent developments. The algorithms discussed are suited for both indefinite and definite integration. They can also be used to compute linear relations among integrals and to find identities for special functions given by parameter integrals. The aim of this present...
