Image manifold revealing for breast lesion segmentation in DCE-MRI.
Bio-medical materials and engineering
Jan 1, 2015
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is widely used for breast lesion differentiation. Manual segmentation in DCE-MRI is difficult and open to viewer interpretation. In this paper, an automatic segmentation method based on i...
Automatic brain MR image denoising based on texture feature-based artificial neural networks.
Bio-medical materials and engineering
Jan 1, 2015
Noise is one of the main sources of quality deterioration not only for visual inspection but also in computerized processing in brain magnetic resonance (MR) image analysis such as tissue classification, segmentation and registration. Accordingly, no...
Nonholonomic mobile system control by combining EEG-based BCI with ANFIS.
Bio-medical materials and engineering
Jan 1, 2015
Motor imagery EEG-based BCI has advantages in the assistance of human control of peripheral devices, such as the mobile robot or wheelchair, because the subject is not exposed to any stimulation and suffers no risk of fatigue. However, the intensive ...
Unsupervised Structure Detection in Biomedical Data.
IEEE/ACM transactions on computational biology and bioinformatics
Jan 1, 2015
A major challenge in computational biology is to find simple representations of high-dimensional data that best reveal the underlying structure. In this work, we present an intuitive and easy-to-implement method based on ranked neighborhood compariso...
A Hybrid Loss for Multiclass and Structured Prediction.
IEEE transactions on pattern analysis and machine intelligence
Jan 1, 2015
We propose a novel hybrid loss for multiclass and structured prediction problems that is a convex combination of a log loss for Conditional Random Fields (CRFs) and a multiclass hinge loss for Support Vector Machines (SVMs). We provide a sufficient c...
Enhancing Patient Safety Event Reporting by K-nearest Neighbor Classifier.
Studies in health technology and informatics
Jan 1, 2015
Data quality was placed as a major reason for the low utility of patient safety event reporting systems. A pressing need in improving data quality has advanced recent research focus in data entry associated with human factors. The debate on structure...
Facilitating Full-text Access to Biomedical Literature Using Open Access Resources.
Studies in health technology and informatics
Jan 1, 2015
Open access (OA) resources and local libraries often have their own literature databases, especially in the field of biomedicine. We have developed a method of linking a local library to a biomedical OA resource facilitating researchers' full-text ar...
A Statistical Analysis of Term Occurrences in Radiology Reporting.
Studies in health technology and informatics
Jan 1, 2015
To compare term occurrences in free-text radiology reports and RSNA reporting templates, we selected five templates from an RSNA reporting template library and their corresponding free-text reports as a test set, and employed the Wilcoxon signed-rank...
Annotation methods to develop and evaluate an expert system based on natural language processing in electronic medical records.
Studies in health technology and informatics
Jan 1, 2015
The objective of the SYNODOS collaborative project was to develop a generic IT solution, combining a medical terminology server, a semantic analyser and a knowledge base. The goal of the project was to generate meaningful epidemiological data for var...
Automated Detection of Health Websites' HONcode Conformity: Can N-gram Tokenization Replace Stemming?
Studies in health technology and informatics
Jan 1, 2015
Authors evaluated supervised automatic classification algorithms for determination of health related web-page compliance with individual HONcode criteria of conduct using varying length character n-gram vectors to represent healthcare web page docume...
