Highly detailed natural scenes and objects tend to be perceived as being realistic, while repeated parts and patterns decrease their realism. To avoid scenes with noticeable repeated elements, we introduce the notion of ’more of the same’, which focuses on the task of generating additional similar instances from a small set of exemplars. The small number of exemplars, as well as their diversity...

In this work we address the task of computerassisted assessment of short student answers. We combine several graph alignment features with lexical semantic similarity measures using machine learning techniques and show that the student answers can be more accurately graded than if the semantic measures were used in isolation. We also present a first attempt to align the dependency graphs of the...

Several learning tasks comprise hierarchies. Comparison with a ”goldstandard” is often performed to evaluate the quality of a learned hierarchy. We assembled various similarity metrics that have been proposed in different disciplines and compared them in a unified interdisciplinary framework for hierarchical evaluation which is based on the distinction of three fundamental dimensions. Identifyi...

Several attributes of students, as the primary participants of e-learning systems, have been major subjects of intense research over the past decade. Prior research findings identified a set of 31 determinants that have a significant effect on satisfaction and learning outcomes [Bitzer and Janson, 2014]. Structural equation modeling is applied to examine the effects of intrinsic motivation, ext...

structural repetitive subsequences are most important portion of biological sequences, which play crucial roles on corresponding sequence’s fold and functionality. biggest class of the repetitive subsequences is “transposable elements” which has its own sub-classes upon contexts’ structures. many researches have been performed to criticality determine the structure and function of repetitive su...

the purpose of this study was to investigate the mediating role of learning goal orientation at the individual, group and organizational level in the relationship of transformational leadership with adaptive performance. the sample consisted of 175 employees of a service organization. fitness of the proposed model and indirect effects was examined through structural equation modeling and bootst...
