We consider interactive learning and covering problems, in a setting where actions may incur different costs, depending on the response to the action. We propose a natural greedy algorithm for responsedependent costs. We bound the approximation factor of this greedy algorithm in active learning settings as well as in the general setting. We show that a different property of the cost function co...

This study was an attempt to analyze the applications and problems of conducting blended learning (BL) in view point of the agricultural students from Bu-Ali Sina University. The study has employed a surveying methodology with interviewing and included a combination of descriptive and quantitative research methods. Statistical population of the study included 500 agricultural students from Bu-A...

a survey was made to compare the clinical education problems viewed by nursing instructors an senior nursing students in nursing-midwifery colleges affiliated to the faculty of medicine in isfahan (iran, 1994).   the purposes of this study were to determine the demographic characteristics of the subject further the clinical instructors' and the students' views regarding problems they ...

if the target of foreign language teaching is to use the language, communicative language teaching (clt) seems to be an ideal teaching model. the goal of teaching with this method is to use the language as a medium of communication (adi, 2012).the application of the communicative approach in teaching english as a foreign language, however, is associated with some problems that can cause the met...

This paper focuses on Active Learning (AL) with bounded computational resources. AL is formalized as a finite horizon Reinforcement Learning problem, and tackled as a single-player game. An approximate optimal AL strategy based on tree-structured multi-armed bandit algorithms and billiard-based sampling is presented together with a proof of principle of the approach.
