Although it is widely believed that information literacy (IL) skills are useful in helping students perform better, academically or otherwise, limited empirical evidence is available showing the relationship between IL skills and IL education. A quasi-experimental pretestposttest control group study was carried out to investigate the impact of IL teaching approaches, which are grounded in pedag...

My dissertation research centers on application of machine learning techniques to speed up problem solving. In fact, many speed-up learning systems suffer from the utiliv problem; time after learning is greater than time before learning. Discovering how to assure that learned knowledge will in fact speed up system performance has been a focus of research in explanation-based learning (EBL). One...

In this paper we describe our machine learning approach to the generation of referring expressions. As our algorithm we use memory-based learning. Our results show that in case of predicting the TYPE of the expression, having one general classifier gives the best results. On the contrary, when predicting the full set of properties of an expression, a combined set of specialized classifiers for ...

Imitation Learning (IL) is a popular approach for teaching behavior policies to agents by demonstrating the desired target policy. While the approach has lead to many successes, IL often requires a large set of demonstrations to achieve robust learning, which can be expensive for the teacher. In this paper, we consider a novel approach to improve the learning efficiency of IL by providing a sha...

many medical universitiesaround the world have donestunning changes in the recent years.some of these changes have been performed with the support of international organizations.they changed the traditionaltrainingprograms based on teacher- centered learning and disciplined approach to the educational course based on community needs responsivity and student-centered learning. this process is ai...

This article reports a contextual model of information literacy (IL) which emerged from an exploratory case study of IL in a joint online distance learning (ODL) Geographic Information Sciences/Systems (GIS) programme and demonstrates how it contributes to the development of information literate GIS learners in ODL environments. Adopting Eisenhardt’s (1989) “process of building theories from ca...

Background: Stress predisposes organisms to depression and cognitive impairments, and seems to interact with metabolic homeostasis. The inflammatory response and the upregulation of proinflammatory cytokines are some of the consequences related to chronic stress. In this study, we investigated the preventive effect of chronic administration of ibuprofen, as an inhibitor of cyclooxygenases, on t...

In this work we propose a new paradigm for learning coordination in multi-agent systems. This approach is based on social interaction of people, specially in the fact that people communicate to each other what they think about their actions and this opinion has some influence in the behavior of each other. We propose a model in which multi-agents learn to coordinate their actions giving opinion...

this paper illustrates the design and implementation of fain (filtering agent for internet) based on the gaia methodology and the auml notation. the proposed system generates and maintains a user profile by learning from examples that are judged and classified by the user during the training stage. a learning algorithm which is based on the baldwin effect that combines learning with evolution i...

in this paper we have proposed an approach for emotion detection in implicit texts. we have introduced a combinational system based on three subsystems. each one analyzes input data from a different aspect and produces an emotion label as output. the first subsystem is a machine learning method. the second one is a statistical approach based on vector space model (vsm) and the last one is a key...
