Sejnowski and Scott Makeig Swartz Center for Computational Neuroscience University of California San Diego La Jolla, California and Computational Neurobiology Laboratory The Salk Institute for Biological Studies La Jolla, California The Network on Computational Statistics and Machine Learning (NCSML) is awarding funding to support five projects up to a value of 2K for Postdoctoral Research Assistants (PDRAs). The goal is to facilitate collaboration among young researchers working in any exciting topic in computational statisti The Imaging Computational Microscope (ICM) is a suite of computational tools for automated analysis of functional imaging data that runs under the cross-platform MATLAB environment (The Mathworks A variety of new signal processing methods have been applied to EEG signal processing over the past fifteen years [1].These new methods require new tools to allow routine processing of EEG data, and also make possible the analysis of multimodal data collected using more complex experimental designs than previous analysis methods allowed. Important requirements for the analysis of multichannel EEG data are efficient techniques for signal enhancement, signal decomposition, feature extraction, and dimensionality reduction. We propose a new approach for spatial harmonic analysis (SPHARA) that extends the classical spatial Fourier analysis to EEG sensors positioned non-uniformly on the surface of the head. High-frequency oscillations (HFOs) in the electroencephalogram (EEG) are thought to be a promising marker for epileptogenicity. A number of automated detection algorithms have been developed for reliable analysis of invasively recorded HFOs. However, invasive recordings are not widely applicable since they bear risks and costs, and the harm of the surgical intervention of implantation needs to Artefactual data windows were removed using an automated method that rejects outlier values on the basis of different statistics (amplitude, linear trend, joint probability and kurtosis) 23,24 A Computational Framework to Support the Automated Analysis of Routine Electroencephalographic Data A Dissertation Presented to the Graduate School of Clemson University In Partial Ful llment of the Requirements for the Degree Doctor of Philosophy Computer Science William Buck Sparkman Pressly, Jr. August 2010 Accepted : This informatics project applies industrial standards and methods to development of an image data warehouse framework for multimedia management, data analysis, research, and access services. The framework is a complete description of the problem that abstracts the many aspects of epilepsy research and care to a high level of visual understanding. NNK02071SPIŠAnemüller et al.: Complex ICA of Frequency-Domain EEG Data 1 Complex Independent Component Analysis of Frequency-Domain Electroencephalographic Data Jörn Anemüller, Terrence J. Sejnowski and Scott Makeig Swartz Center for Computational Neuroscience Institute for Neural Computation University of California San Diego hctsa: A Computational Framework for Automated Time-Series method for relating these complex data streams to scientifically meaningful outcomes, methods in an approach termed highly comparative time-series analysis. Research Support, N.I.H., Extramural; Research Support, Non-U.S. Gov't Abstract. The electroencephalogram (EEG) is a non-invasive measure of brain electrical activity recorded as changes in potential difference between points on the human scalp. Because of volume conduction through cerebrospinal fluid, skull and scalp, EEG data collected from any point on the scalp includes activity from processes occurring within Independent component analysis (ICA) is effective in analyzing brain signals and in particular electroencephalographic (EEG) data (e.g. Makeig, Bell, Jung, & Sejnowski, 1996; Makeig et al., 2002), and ICA continues to be useful for building new models of experimental data. However, ICA algorithms presently applied to brain data rely on several idealized assumptions about the underlying processes Computational framework to support integration of biomolecular and clinical data within a translational approach. Miyoshi NS(1), Pinheiro DG, The pre-operative workup of patients with drug-resistant epilepsy requires in some candidates the identification from intracranial EEG (iEEG) of the seizure-onset zone (SOZ), defined as the area responsible of the generation of the seizure and therefore candidate for resection. High-frequency oscillations (HFOs) contained in the iEEG signal have been proposed as biomarker of the SOZ. The hybrid brain computer interface (BCI) based on motor imagery (MI) and P300 has been a preferred strategy aiming to improve the detection performance through combining the features of each. However, current methods used for combining these two modalities optimize them separately, which does not result in optimal performance. Here, we present an efficient framework to optimize them together A representation and interpretation of the area under a receiver operating characteristic (ROC) curve obtained the "rating" method, or mathematical predictions The EEG Study Schema (ESS) comprises three data Levels, each with its own XML-document schema and file/folder convention, plus a standardized (PREP) pipeline to move raw (Data Level 1) data to a basic preprocessed state (Data Level 2) suitable for application of a large class of EEG analysis methods. Computational testing for automated preprocessing: a matlab toolbox for better electroencephalography data processing with a large choice of methods for analysis, but no framework for method In most research applications EEG data can be very large; systems are available with over 256 channels. This can result in the need to examine thousands or tens of thousands of data-points; for instance, visual examination of raw data quality for 50 subjects 256 channels 1,200 s 16,000 plot windows (where each window shows 32 channels 30 s). CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Because of the distance between the skull and brain and their different resistivities, electroencephalographic (EEG) data collected from any point on the human scalp includes activity generated within a large brain area. This spatial smearing of EEG data volume conduction does not involve significant time delays criminant functions for support vector machines (SVMs) addressing separable and nonseparable contexts, and provide an objective experimental comparison of several feature selection methods, which also evaluates consistency between a classifler s margin and its generalization accuracy.
