Reduction of False Positive signals (FPR) is a fundamental, yet awkward, step in computer aided mass detection schemes. This paper describes preliminary results of a filtering approach to FPR based on Support Vector Regression (SVR), a machine learning algorithm arising from a well-founded theoretical framework, the Statistical Learning Theory, which has recently proved to be superior to the co...
How to find and detect novel or unknown network attacks is one of the most important objectives in current intrusion detection systems. In this paper, a rule evolution approach based on Genetic Programming (GP) for detecting novel attacks on networks is presented and four genetic operators, namely reproduction, mutation, crossover, and dropping condition operators, are used to evolve new rules....
OBJECTIVE To evaluate the efficacy of first trimester combined screening for Down's syndrome in Northern Finland during the first 10 years of practice. METHODS During 1 January 2002 to 31 December 2011, 47,896 women participated voluntarily in combined screening during first trimester. The risk cutoff was 1:250. The study period was divided into two time periods; 2002-2006 and 2007-2011. RE...
Introduction: Recent studies have acknowledged the potential of convolutional neural networks (CNNs) in distinguishing healthy and morbid samples by using heart sound analyses. Unfortunately the performance of CNNs is highly dependent on the filtering procedure which is applied to signal in their convolutional layer. The present study aimed to address this problem by a...
Through this study we evaluated whether the HIV-1 tropism determined by genotypic analysis correlates with HIV-1 markers, such as CD4 cell count and plasma HIV-RNA. The analysis was performed on 1221 HIV-1 B-subtype infected patients with an available V3 sequence (all maraviroc naive). Of them, 532 were antiretroviral therapy (ART) naive and 689 ART experienced. Tropism determination was perfor...
Rogue nodes broadcasting false information in beacon messages may lead to catastrophic consequences Vehicular Ad Hoc Networks (VANETs). Previous researchers used cryptography, trust scores, or past vehicle data detect rogue nodes; however, these methods suffer from high processing delay, overhead, and False–Positive Rate (FPR). We propose herein Greenshield's traffic model–based fog computing s...
Background BGISEQ-500 is a new desktop sequencer developed by BGI. Using DNA nanoball and combinational probe anchor synthesis developed from Complete Genomics™ sequencing technologies, it generates short reads at a large scale. Here, we present the first human whole-genome sequencing dataset of BGISEQ-500. The dataset was generated by sequencing the widely used cell line HG001 (NA12878) in two...
OBJECTIVE To determine the relative contribution of nuchal translucency (NT) to the biochemical detection rates of combined screening for trisomies 13 and 18 in two healthcare systems practicing different quality-control systems of nuchal measurement. METHODS De-identified data collected from the Fetal Medicine Foundation in the United Kingdom and laboratory data from NTD laboratories in the ...
OBJECTIVES Using deep sequencing methods, we intensively investigated the selective pressure of maraviroc on the viral population in four patients with dual/mixed HIV-1 experiencing treatment failure. METHODS Patients received maraviroc add-on therapy (n = 4). Tropism was determined by Monogram's Trofile assay and/or 'deep' sequencing. Longitudinal 'deep' sequence analysis used triplicate HIV...
The misclassification error which is usually used in tests to compare classification algorithms, does not make a distinction between the sources of error, namely, false positives and false negatives. Instead of summing these in a single number, we propose to collect multivariate statistics and use multivariate tests on them. Information retrieval uses the measures of precision and recall, and s...
