A classification system based on a new wrapper feature selection algorithm for the diagnosis of primary and secondary polycythemia
(2013)Primary and Secondary Polycythemia are diseases of the bone marrow that affect the blood's composition and prohibit patients from becoming blood donors. Since these diseases may become fatal, their early diagnosis is ... -
Classification tree based protein structure distances for testing sequence-structure correlation
(2008)A methodology for testing the correlation between the sequence and structure distances of proteins is proposed. Structure distances were derived by applying a forward growing classification tree algorithm on defined ... -
Examining the stability of genetic risk effect as evidence accumulates in the context of meta-analysis
(2013)The recursive cumulative meta-analysis (RCM) of genetic association studies explores the relative change of the cumulative risk effect (e.g. OR) in time, indicating the stability of risk effect as evidence accumulates. ... -
EXPLORING CHILDREN'S UNDERSTANDING OF DEATH: THROUGH DRAWINGS AND THE DEATH CONCEPT QUESTIONNAIRE
(2013)To investigate whether children's understanding of the concept of death varies as a function of death experience and age, 52 children aged 7, 9, and 11 years (26 had a personal death experience), drew a picture reflecting ... -
Forest classification trees and forest support vector machines algorithms: Demonstration using microarray data
(2010)Classification into multiple classes when the measured variables are outnumbered is a major methodological challenge in -omics studies. Two algorithms that overcome the dimensionality problem are presented: the forest ... -
An implicit evolution scheme for active contours and surfaces based on IIR filtering
(2014)In this work, we present an approach for implementing an implicit scheme for the numerical solution of the partial differential equation of the evolution of an active contour/surface. The proposed scheme is applicable to ... -
MRISIMUL: A GPU-Based Parallel Approach to MRI Simulations
(2014)A new step-by-step comprehensive MR physics simulator (MRISIMUL) of the Bloch equations is presented. The aim was to develop a magnetic resonance imaging (MRI) simulator that makes no assumptions with respect to the ... -
Muscle-driven finite element simulation of human foot movements
(2012)This paper describes a finite element scheme for realistic muscle-driven simulation of human foot movements. The scheme is used to simulate human ankle plantar flexion. A three-dimensional anatomically detailed finite ... -
Non-parametric classification of protein secondary structures
(2006)Proteins were classified into their families using a classification tree method which is based on the coefficient of variations of physico-chemical and geometrical properties of the secondary structures of proteins. The ... -
A tree-based decision rule for identifying profile groups of cases without predefined classes: application in diffuse large B-cell lymphomas
(2007)In this paper, we examined the utility of a forward growing classification tree as a supplement to cluster analysis for deriving a decision rule for the identification of profile groups when the cases do not belong to ...
