Learning machines and sleeping brains: Automatic sleep stage classification using decision-tree multi-class support vector machines.
Journal of neuroscience methods
Jan 25, 2015
BACKGROUND: Sleep staging is a critical step in a range of electrophysiological signal processing pipelines used in clinical routine as well as in sleep research. Although the results currently achievable with automatic sleep staging methods are prom...
Watershed based intelligent scissors.
Computerized medical imaging and graphics : the official journal of the Computerized Medical Imaging Society
Jan 21, 2015
Watershed based modification of intelligent scissors has been developed. This approach requires a preprocessing phase with anisotropic diffusion to reduce subtle edges. Then, the watershed transform enhances the corridors. Finally, a roaming procedur...
Human-inspired sound environment recognition system for assistive vehicles.
Journal of neural engineering
Jan 14, 2015
OBJECTIVE: The human auditory system acquires environmental information under sound stimuli faster than visual or touch systems, which in turn, allows for faster human responses to such stimuli. It also complements senses such as sight, where direct ...
A Novel Method for Automated Diagnosis of Epilepsy Using Complex-Valued Classifiers.
IEEE journal of biomedical and health informatics
Jan 6, 2015
The study reported herein proposes a new method for the diagnosis of epilepsy from electroencephalography (EEG) signals based on complex classifiers. To carry out this study, first the features of EEG data are extracted using a dual-tree complex wave...
Learning-based prediction of gestational age from ultrasound images of the fetal brain.
Medical image analysis
Jan 3, 2015
We propose an automated framework for predicting gestational age (GA) and neurodevelopmental maturation of a fetus based on 3D ultrasound (US) brain image appearance. Our method capitalizes on age-related sonographic image patterns in conjunction wit...
Retinal vessel extraction using Lattice Neural Networks with Dendritic Processing.
Computers in biology and medicine
Dec 31, 2014
Retinal images can be used to detect and follow up several important chronic diseases. The classification of retinal images requires an experienced ophthalmologist. This has been a bottleneck to implement routine screenings performed by general physi...
An infectious disease/fever screening radar system which stratifies higher-risk patients within ten seconds using a neural network and the fuzzy grouping method.
The Journal of infection
Dec 23, 2014
OBJECTIVES: To classify higher-risk influenza patients within 10 s, we developed an infectious disease and fever screening radar system.
Validation of electronic health record phenotyping of bipolar disorder cases and controls.
The American journal of psychiatry
Dec 12, 2014
OBJECTIVE: The study was designed to validate use of electronic health records (EHRs) for diagnosing bipolar disorder and classifying control subjects.
Prediction of the thickness of the compensator filter in radiation therapy using computational intelligence.
Medical dosimetry : official journal of the American Association of Medical Dosimetrists
Dec 11, 2014
In this study, artificial neural networks (ANNs) and adaptive neuro-fuzzy inference system (ANFIS) are investigated to predict the thickness of the compensator filter in radiation therapy. In the proposed models, the input parameters are field size (...
Prediction of revascularization after myocardial perfusion SPECT by machine learning in a large population.
Journal of nuclear cardiology : official publication of the American Society of Nuclear Cardiology
Dec 6, 2014
OBJECTIVE: We aimed to investigate if early revascularization in patients with suspected coronary artery disease can be effectively predicted by integrating clinical data and quantitative image features derived from perfusion SPECT (MPS) by machine l...
