The aim of this study was to investigate the effects of various online techniques (word reference, media, and vocabulary games) on reading comprehension as well as vocabulary comprehension and production. For this purpose, 60 language learners were selected and divided into three groups, and each group was randomly assigned to one of the treatment conditions. In the first session of tre...

The stability of learning rate in neural network identifiers and controllers is one of the challenging issues which attracts great interest from researchers of neural networks. This paper suggests adaptive gradient descent algorithm with stable learning laws for modified dynamic neural network (MDNN) and studies the stability of this algorithm. Also, stable learning algorithm for parameters of ...

Introduction: Unlike the face-to-face courses offered on campus, online courses are predominantly asynchronous, where students basically decide when they can attend online courses. There is also an intermediate method referred to as blended learning (BL) that combines the merits of both methods. This study investigates the effect of blended learning on attitude and learning applied Biostatistic...

‎Rough extreme learning machines (RELMs) are rough-neural networks with one hidden layer where the parameters between the inputs and hidden neurons are arbitrarily chosen and never updated‎. ‎In this paper‎, ‎we propose RELMs with a stable online learning algorithm for the identification of continuous-time nonlinear systems in the presence of noises and uncertainties‎, ‎and we prove the global ...

In this paper we develop a mechanism for critic-based learning in continuous state and action spaces. Our approach is based on the Motoric Map model [RMS90], by which we wish to overcome the restrictions of traditional Reinforcement Learning methods concerning continuous spaces. Covariance Learning is introduced as algorithm to determine the best possible action for a given state using the crit...

Intersexuality, as the philosophical foundation of college English teaching and learning under the network environment, facilitates integration of educational technology and foreign language teaching. On the basis of this philosophical idea, the author advances three principles to follow in college English teaching and learning through online learning community: mutual respect and equal dialogu...
