this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...

Classical and recent results in statistical pattern recognition and learning theory are reviewed in a two-class pattern classification setting. This basic model best illustrates intuition and analysis techniques while still containing the essential features and serving as a prototype for many applications. Topics discussed include nearest neighbor, kernel, and histogram methods, Vapnik–Chervone...

Vapnik-Chervonenkis (VC) bounds play an important role in statistical learning theory as they are the fundamental result which explains the generalization ability of learning machines. There have been consequent mathematical works on the improvement of VC rates of convergence of empirical means to their expectations over the years. The result obtained by Talagrand in 1994 seems to provide more ...

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...

This study was undertaken to examine the relationship between theory of mind and academic anxiety mediated by motivational learning strategies among a group of high school students. The present study had a descriptive, correlational design. The statistical population of the study included all female 9th graders studying in public high schools in Qaemshahr in 2019-2020 school year. The sample si...

Piecewise Linear-Quadratic (PLQ) penalties are widely used to develop models in statistical inference, signal processing, and machine learning. Common examples of PLQ include least squares, Huber, Vapnik, 1-norm, their asymmetric generalizations. Properties these estimators depend on the choice penalty its shape parameters, such as degree asymmetry for quantile loss, transition point between li...

We study annealed theories of learning boolean functions using a concept class of nite cardinality The naive annealed theory can be used to derive a univer sal learning curve bound for zero temperature learning similar to the inverse square root bound from the Vapnik Chervonenkis theory Tighter nonuniversal learning curve bounds are also derived A more re ned annealed theory leads to still tigh...
