The present study aims at improving the characterization of myocardial velocities in the context of heart failure with preserved ejection fraction (HFPEF) by combining multiple descriptors. It builds upon a recent extension of manifold learning known as multiple kernel learning (MKL), which allows the combination of data of di↵erent natures towards the learning. Such learning is kept unsupervis...

In this paper, we suggest multiple kernel learning with hierarchical feature representations. Recently, deep learning represents excellent performance to extract hierarchical feature representations in unsupervised manner. However, since fine-tuning step of deep learning only considers global level of features for classification problems, it makes each layers hierarchical features intractable. ...

Although the detrimental effects of math anxiety in adults are well understood, few studies have examined how it affects younger children who are beginning to learn math in a formal academic setting. Here, we examine the relationship between math anxiety and math achievement in second and third graders. In response to the need for a grade-appropriate measure of assessing math anxiety in this gr...

I. ABSTRACT This fifth grade unit utilizes practical applications of mathematics in the “real world.” During this interactive approach to learning “math wisdom,” students will gain knowledge of number sense, computation, ratios and proportions, probabilities and statistics, and money. The students will experience various critical thinking scenarios that build upon the Core Knowledge Math Curric...

Frank presents an alternative interpretation of our data, yet reports largely similar results to those in our original Report. A critical difference centers on how to interpret and test interaction effects. Frank finds no mistakes in our analyses. We stand by our original conclusions of meaningful effects of the Bedtime Learning Together (BLT) math app on children's math achievement.

Research over the past twentyve years indicates that gender di erences in math achievement favoring males are not typically found prior to high school. In high school, di erences favoring males are common, particularly in the areas of problem solving and applications. The gender-related di erences in math achievement have been attributed to a number of variables, most notably, di erential cours...

MathGirls is a pedagogical-agent-based environment designed for high-school girls learning introductory algebra. Since females are in general more interested in interactive computing and more positive about the social presence of pedagogical agents, the environment provides a girl-friendly social learning environment, where pedagogical agents encourage the girls to build constructive views of l...
