Los sistemas alternativos y aumentativos de comunicación (SAAC) como instrumento para disminuir conductas desafiantes en el alumnado con TEA: estudio…
2017
Resumen Se describe una intervención, basada en el Programa de Habla Signada de Benson Schaeffer, para dotar de un Sistema Alternativo y Aumentativo de Comunicación (SAAC) a una niña de ocho años diagnosticada con trastorno del espectro autista (TEA). Se pretende que la alumna, mediante la utilización de signos, pueda expresar sus necesidades y disminuir las conductas desafiantes que propicia, ya que se estima que estas tienen una clara intención comunicativa. Se utiliza una metodología cualitativa de estudio de caso único y por objetivos. El programa se desarrolló en el aula de comunicación y lenguaje (CyL) de un centro público de educación infantil y primaria (CEIP) de la Comunidad Valenc…
Alleviating Class Imbalance Problem in Automatic Sleep Stage Classification
2022
For real-world automatic sleep-stage classification tasks, various existing deep learning-based models are biased toward the majority with a high proportion. Because of the unique sleep structure, most of the current polysomnography (PSG) datasets suffer an inherent class imbalance problem (CIP), in which the number of each sleep stage is severely unequal. In this study, we first define the class imbalance factor (CIF) to describe the level of CIP quantitatively. Afterward, we propose two balancing methods to alleviate this problem from the dataset quantity and the relationship between the class distribution and the applied model, respectively. The first one is to employ the data augmentati…
Remote Sensing of 3-D Geometry and Surface Moisture of a Peat Production Area Using Hyperspectral Frame Cameras in Visible to Short-Wave Infrared Spe…
2016
Miniaturized hyperspectral imaging sensors are becoming available to small unmanned airborne vehicle (UAV) platforms. Imaging concepts based on frame format offer an attractive alternative to conventional hyperspectral pushbroom scanners because they enable enhanced processing and interpretation potential by allowing for acquisition of the 3-D geometry of the object and multiple object views together with the hyperspectral reflectance signatures. The objective of this investigation was to study the performance of novel visible and near-infrared (VNIR) and short-wave infrared (SWIR) hyperspectral frame cameras based on a tunable Fabry–Pérot interferometer (FPI) in measuring a 3-D digital sur…
