A major impairment to the implementation of PEM analysis for clinical assessment of neurodegenerative disorders includes the time consuming aspects for both visual and automated supervised methods, which require exhaustive expert scoring of PEM and non-PEM events. In order to surmount the aforementioned concerns, we propose a semi-supervised classification methodology encased within an easy-to-use graphical user interface (GUI) utilizing an embedded Minimum Description Length (MDL) criterion to automatically classify PEM and non-PEM events based on expert labeling of a single PEM instance. Results indicate that the application of a semi-supervised approach for PEM identification provides an excellent option to reduce the labeling burden within current human PSG muscle activity identification schemes.

SAX offers potential benefits for time series analysis of PSGs that include: 1) dimensionality and storage space reduction and 2) access to robust symbolic based data mining algorithms, such as intelligent icons. To evaluate the proposed symbolic classification scheme we compare, expert visual scoring of phasic EMG activity, a reliable quantitative metric to assist in discriminating neurodegenerative disorder populations and age-matched controls, to a k-Nearest Neighbor intelligent icon based SAX scheme. Detection of non-phasic EMG activity exceeded 90% and detection of phasic EMG activity ranged between 53 to 90 %, for six subjects.

These disparities among the number of whites and minorities who pursue graduate studies are apparent in the findings of Foertsch[1] The latter reported that about 30% of whites with a BS degree go on to graduate school, while only 19% of non-Asian minorities with a BS do the same. In 1995, blacks accounted for only 2.0% of all STEM PhDs, Hispanics for 2.5%, and American Indians for 0.3% - even though within the same year African Americans made up about 12% of the U.S. population, Hispanics 10.2%, and American Indians 0.7%.

High rates of such activity may have clinical relevance. This paper presents wavelet (WT) analyses to detect phasic EMG, examining both Symlet and Daubechies approaches. Feature extraction included 1 s epoch processing with 24 WT-based features and dimensionality reduction involved comparing two techniques: principal component analysis and a feature/variable selection algorithm. Classification was conducted using a linear classifier. Valid automated detection was obtained in comparison to expert human judgment with high (490%) classification performance for 11/12 datasets.

The fifth edition of The Cognitive Neurosciences continues to chart new directions in the study of the biological underpinnings of complex cognitio -- the relationship between the structural and physiological mechanisms of the nervous system and the psychological reality of the mind. It offers entirely new material, reflecting recent advances in the field. Many of the developments in cognitive neuroscience have been shaped by the introduction of novel tools and methodologies, and a new section is devoted to methods that promise to guide the field into the future -- from sophisticated models of causality in brain function to the application of network theory to massive data sets. Another new section treats neuroscience and society, considering some of the moral and political quandaries posed by current neuroscientific methods. Other sections describe, among other things, new research that draws on developmental imaging to study the changing structure and function of the brain over the lifespan; progress in establishing increasingly precise models of memory; research that confirms the study of emotion and social cognition as a core area in cognitive neuroscience; and new findings that cast doubt on the so-called neural correlates of consciousness.

We undertook this study because we suspected that even expert scorers may disagree on whether a given EMG segment contained phasic activity, tonic activity, or both. Six individuals holding either Fellowship status in the American Academy of Sleep Medicine or Board Certification in Sleep Medicine with at least 5 years' experience in interpreting polysomnography visually examined 60 segments containing EMG activity. Raters determined their relative confidence that each segment contained phasic and tonic activity by noting whether they were highly certain or somewhat certain that the segment contained such activity or somewhat certain or highly certain that each segment did not contain such activity. Every segment was rated by every rater twice, once for phasic and once for tonic activity. Substantial differences among raters existed in ...

The focus of this work is to describe a successful approach to teaching research skills to undergraduate students by combining laboratory experience with weekly instructional seminars in an attempt to foster future success in graduate school. This approach was designed and implemented for a ten-week summer research experience program for undergraduate students. The weekly instructional seminar series addressed research skills in three key areas: communication, investigation, and documentation. The seminar series began with the “Communications Seminars,” where student participants learned how to concisely explain their research topics through an ‘elevator talk’ activity, a common exercise utilized in business fields. Followed by “Investigation Seminars,” that addressed conducting literature reviews and creating annotated bibliographies. Instructions on formulating and maint...

Current technological trends in psg analysis focus upon translating manual psg analysis into automated/computerized approaches. A necessary first step in establishing efficient automated human sleep analysis systems is the development of reliable pre-processing tools to discriminate between outlier/artifact instances and data of interest. This paper investigates the application of an automated approach, using the generalized singular value decomposition algorithm, to compensate for specific psg artifacts.

Signal Processing for Neuroscientists introduces analysis techniques primarily aimed at neuroscie... more Signal Processing for Neuroscientists introduces analysis techniques primarily aimed at neuroscientists and biomedical engineering students with a reasonable but modest background in mathematics, physics, and computer programming. The focus of this text is on what can be considered the 'golden trio' in the signal processing field: averaging, Fourier analysis, and filtering. Techniques such as convolution, correlation, coherence, and wavelet analysis are considered in the context of time and frequency domain analysis. The whole spectrum of signal analysis is covered, ranging from data acquisition to data processing; and from the mathematical background of the analysis to the practical application of processing algorithms. Overall, the approach to the mathematics is informal with a focus on basic understanding of the methods and their interrelationships rather than detailed proofs or derivations. One of the principle goals is to provide the reader with the background required to understand the principles of commercially available analyses software, and to allow him/her to construct his/her own analysis tools in an environment such as MATLAB®.

"""""""Data Science involves the blending of techniques and theories from various disciplines inc... more """""""Data Science involves the blending of techniques and theories from various disciplines including mathematics, statistics, engineering, and computer science, to conduct data mining, in order to elicit substantial information from datasets. The interdisciplinary nature of data science provides a wide platform for the utilization and development of powerful computational tools to tackle an array of real world data sets. In this talk, I will discuss my data science based approach in processing human polysomnograms (psgs), sleep records.
The human psg consists of a collection of bio-physiological events recorded simultaneously over many hours. Multiple non-invasive electrodes, located on different body regions, are used to obtain information regarding physiological state fluctuations of the subject in order to access sleep health. Although, information regarding healthy adult sleep is well characterized the establishment of robust models for sleep in patients suffering from certain sleep disorders and neurological pathologies are still being demystified. The delay in understanding the sleep patterns of these patients can be contributed to the need for efficient approaches to analyze the large, complex, and at times noisy records generated from sleep studies.
In order to meet this need, I have used a combination of signal processing, machine learning, and statistical modeling techniques to probe psgs and obtain information regarding the human sleep cycle of patients with sleep disorders and neurological pathologies. More specifically, I focus on pre-processing, data characterization, and post-processing challenges. My investigations indicate that Data Science offers many robust tools to hasten understanding of the human sleep cycle with respect to pathological conditions.
