Concept indexing in multimedia libraries is very useful for users searching and browsing but it is a very challenging research problem as well. Beyond the systems’ implementations issues, semantic indexing is strongly dependent upon the size and quality of the training examples. In this paper, we describe the collaborative annotation system used to annotate the High Level Features (HLF) in the ...

This project involved the use of two small, closely matched non-majors introductory biology classes to test the use of the Jigsaw method of teaching vs. a passive, instructor-oriented model of teaching. In this study, the Jigsaw method was used as a jumping off point for the teaching-learning of the material. Students were to learn the concepts of the chapters through the Jigsaw method and thei...

In many real-world tasks of image classification, limited amounts of labeled data are available to train automatic classifiers. Consequently, extensive human expert involvement is required for verification. A novel solution is presented that makes use of active learning combined with an ensemble of classifiers for each class. The result is a significant reduction in required expert involvement ...

Unsupervised active learning has been an research topic in machine community, with the purpose of choosing representative samples to be labelled unsupervised manner. Previous works usually take minimization data reconstruction loss as criterion select which can better approximate original inputs. However, are often drawn from low-dimensional subspaces embedded arbitrary high-dimensional space m...

the main issues in any society are teaching and learning and main elements of this story are the teacher and the learner. there are different psychology schools in which any of them in turn, have taken many extensive researches about behavior, and facts and theories of learning have been studied from a particular perspective. rationalism asserts that the human intellect has the highest energy a...

In their seminal work Active Learning: Creating Excitement in the Classroom, compiled in 1991 for the Association for the Study of Higher Education and the ERIC Clearinghouse on Higher Education, Bonwell and Eison defined strategies that promote active learning as “instructional activities involving students in doing things and thinking about what they are doing” (Bonwell and Eison, 1991). Appr...

Almost everyone has turned to the internet to vet a product before purchase. Some online retailers – like amazon.com – even provide you with recommendations for products you might like. In this age of online retailers and multiple anonymous raters, it is a worthwhile goal to use the pool of collective knowledge and opinions to guide product recommendations. The objective of recommender systems ...
