Automatic genre classification of audio signals is an open challenge of pattern recognition. The fractal nature of the music signals indicates the Hausdorff dimension as a distinguish feature for classifying audio tracks. However this key parameter cannot be unequivocally defined since it is not constant during the whole track, but it ranges in a wide set of values. The aim of this paper is to ...

Bounds are given for the empirical and expected Rademacher complexity of classes of linear transformations from a Hilbert space H to a …nite dimensional space. The results imply generalization guarantees for graph regularization and multi-task subspace learning. 1 Introduction Rademacher averages have been introduced to learning theory as an e¢ cient complexity measure for function classes, mot...

This study examined whether the relationship between reward structure and team performance is contingent upon task dimension, team composition, and individual performance level. Seventy-five four-person teams engaged in a simulated interactive task in which reward structure was manipulated. A competitive structure enhanced one task dimension, speed, whereas a cooperative structure enhanced accu...

A method using discrete cross-correlation for identifying and removing spurious Lyapunov exponents when embedding experimen tal data in a dimension greater than the origina l system is introduce d. The method uses a distribution of calculated exponent values produced by modeling a single time series many times or multiple instances of a time series. For this task, global models are shown to com...

This paper deals with the problem of recovering the dimensions of an object and its pose from a single image acquired with a camera of unknown focal length. It is assumed that the object in question can be modeled as a polyhedron where the coordinates of the vertices can be expressed as a linear function of a dimension vector, . The reconstruction program takes as input a set of correspondences...

BACKGROUND Single-domain antibody fragments possess structural features, such as a small dimension, an elevated stability, and the singularity of recognizing epitopes non-accessible for conventional antibodies that make them interesting for several research and biotechnological applications. RESULTS The discovery of the single-domain antibody's potentials has stimulated their use in an increa...

background: spiritual well-being (swb) of patients with cardiovascular diseases particularly in those admitted in coronary care unit (ccu) is threatened due to disease crisis. therefore, implementing spiritual care is necessary for them. this study aimed to determine the effect of spiritual care program on swb of patients with cardiac ischemia admitted in ccu in al-zahra hospital, isfahan, iran...

Introduction: The current study aimed to elucidate the role of preparatory cognitive control in decision making and its neural correlates using functional Magnetic Resonance Imaging (fMRI). To this effect, by employing a series of new cognitive tasks, we assessed the role of preparatory cognitive control in monetary (risky) decision making. Methods: The participants had to decide between a...

Task variation is an integrative method aiming at the importance of learner-to-learner interactions in a wide range of learning contexts and fostering authentic use of language and meaningful communication. This study investigated the impact of task variation on the accuracy and complexity of Iranian EFL learners’ oral speech. In so doing, 80 intermediate EFL learners, majoring English at the I...
