Ensemble learning techniques and in particular Random Forests have been one of the most successful machine learning approaches of the last decade. Despite their success, there exist barely suitable visualizations of Random Forests, which allow a fast and accurate understanding of how well they perform a certain task and what leads to this performance. This paper proposes an exemplar-driven visu...

A method for transforming performance evaluation signals distal both in space and time into proximal signals usable by supervised learning algorithms, presented in [Jordan & Jacobs 90], is examined. A simple observation concerning differentiation through models trained with redundant inputs (as one of their networks is) explains a weakness in the original architecture and suggests a modificatio...

We discuss try to identify ”gestures” in music performances by observing patterns in both compositional and expressive properties, and by modelling them with a statistical approach. Assuming a finite number of latent states on each property value, we can describe those gestures with statistical latent state models, and train them by unsupervised learning algorithms. Results for several recorded...

Background: Today, the prevalence of learning disabilities is increasing among students. These disorders are categorized in three categories: reading disorder, mathematics disorder, impairment is written on academic performance that affect on educational and social performance of children. Students play an important role as human resources, then, achieving useful strategies are necessary. The a...

BACKGROUND AND AIM: Individual’s learning style determines the mechanism of processing, internalization, and retention of new information. The higher education centers and professors need information and conformity to various learning styles to help students learn effectively. In addition, researchers believe that learning styles are one of the factors responsi...

teachers’ beliefs greatly influence their performance in the classroom, their choice of instructional strategies, their way of controlling the class, their dealing with the students, and their general goals and objectives. one of these beliefs is teachers’ sense of efficacy which is viewed as an important construct and has shown to be positively correlated with students’ achievement (ross, 1992...

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...

Introduction: VARK learning styles are included visual, listening, reading and writing and performance styles or movement (learning by touching, hearing, smelling, tasting and seeing) styles. The aim of this study was to determine students' learning styles preference and their relationships in Medical Sciences students. Materials and Methods: This was a Cross-sectional study in which 80 ...
