Factor analysis and discriminant analysis are often used as complementary approaches to identify linear components in two dimensional data arrays. For three dimensional arrays, which may organize data in dimensions such as space, time, and trials, the opportunity arises to combine these two approaches. A new method, Bilinear Discriminant Component Analysis(More)
This review summarizes linear spatiotemporal signal analysis methods that derive their power from careful consideration of spatial and temporal features of skull surface potentials. BCIs offer tremendous potential for improving the quality of life for those with severe neurological disabilities. At the same time, it is now possible to use noninvasive(More)
Traditional analysis methods for single-trial classification of electro-encephalography (EEG) focus on two types of paradigms: phase locked methods, in which the amplitude of the signal is used as the feature for classification , e.g. event related potentials; and second order methods, in which the feature of interest is the power of the signal, e.g. event(More)
Traditional analysis methods for single-trial classification of electro-encephalography (EEG) focus on two types of paradigms: phase-locked methods, in which the amplitude of the signal is used as the feature for classification, that is, event related potentials; and second-order methods, in which the feature of interest is the power of the signal, that is,(More)
To identify Binteresting[ images, human observers view 10 images/sec, while electroencephalography (EEG) signals from the observers own brains are automatically decoded. ABSTRACT | Our society's information technology advancements have resulted in the increasingly problematic issue of information overloadVi.e., we have more access to information than we can(More)
— The conventional goal for a brain-computer interface has been to restore, for paralyzed individuals, a seamless interaction with the world. The shared vision in this research area is that one-day patients will control a prosthetic device with signals originating directly from their brain. This review provides a new perspective on the brain-computer(More)
Managing construction and demolition (C&D) wastes has challenged many municipalities with diminishing waste disposal capacity. Facing such challenges, the Massachusetts Department of Environmental Protection proposed a policy restricting the landfill disposal of certain C&D waste materials, if unprocessed. This research is to study the potential economic(More)
BACKGROUND AND AIMS To measure the prevalence of overweight and obesity in adults in the Republic of Cyprus, and to evaluate and relate possible obesity risk factors of the adult Cypriot population. METHODS This is an epidemiological cross-sectional study on a stratified random sample of 1001 (48.5% males-51.5% females) subjects, aged 18-80 years old.(More)
A key objective in systems and cognitive neuroscience is to establish associations between behavioral measures and concurrent neuronal activity. Single-trial analysis has been proposed as a novel method for characterizing such correlates by first extracting neural components that maximally discriminate trials on a categorical variable, (e.g., hard vs. easy,(More)
