In this project, by using different learning algorithms in the form of 37 input parameters of network for predicting average considering effective factors in learning and educational progress, the Perceptron artificial neural network have been studied. The requisite data have been obtained through handing out questionnaires between 400 students of Payame Noor University majoring in computer engineering, information technology and computer science. For recognizing the best learning algorithm, 13 common algorithms considering factors such as training time, the percentage of accountability, the index of efficiency ( the mean squared errors), and the number of epoch have been studied after error propagation. Finally the LM algorithm was recognized as the best learning algorithm for prediction of average.
Signal Detection, is a very important issue in cognitive networks. Therefore it is necessary to have a criterion for evaluating the degree of correctness and reliability of the signals. In this paper, we used the separability degree as a criterion for separating and identifying noise from the main signal. This method supposes two states for our signal that are false detection of weak signal, and correct detection of the main signal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
