In this paper, we present two learning mechanisms for artificial neural networks (ANN's) that can be applied to solve classification problems with binary outputs. These mechanisms are used to reduce the number of hidden units of an ANN when trained by the cascade-correlation learning algorithm (CAS). Since CAS adds hidden units incrementally as learning proceeds, it is difficult to predict the ...

Background: Food insecurity and hunger not only affect physical health, but also have social and psychological effects. Therefore, providing food security for society is one of the major goals of social and economical development programs. The objective of this study was to determine the prevalence and intensity of food insecurity at North West of Tabriz as a population sample of East Azerb...

in the qur'an, men and women are equal in terms of human dignity and spiritual interest and faith; but god did not speak to women immediately and directly; especially in law verses, god speaks to men directly but he speaks to women as a third person (hidden person). in this paper, this problem has been analyzed in view of divine-social tasks in the quran and it became clear that god has gi...

Ecosystems consist of complex dynamic interactions among species and the environment, the understanding of which has implications for predicting the environmental response to changes in climate and biodiversity. Understanding the nature of functional relationships (such as prey-predator) between species is important for building predictive models. However, modelling the interactions with extern...

BACKGROUND Current guidelines for a check-up recommend routine screening not triggered by specific symptoms for some known risk factors and diseases in the general population. Patients' perceptions and expectations regarding a check-up exam may differ from these principles. However, quantitative and qualitative data about the discrepancy between patient- and provider expectations for this type ...

The present study was an attempt to investigate the possible role of the hidden curriculum onacademic achievements of high school students and to provide a plausible model to decrease the negative effects of the hidden curriculum. Research method was mixed. The statistical population was all female high school students.The sample comprised 9 high school who were purposeful sampling selected the...
