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)
[ Application to performance augmentation in high-throughput tasks ] T he 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.(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)

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)
Eye-tracking has been extensively used to quantify audience preferences in the context of marketing and advertising research, primarily in methodologies involving static images or stimuli (i.e., advertising, shelf testing, and website usability). However, these methodologies do not generalize to narrative-based video stimuli where a specific storyline is(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)
