Recent Findings from University of Science Malaysia Has Provided New Information about Clinical Trials and Studies

June 16, 2014

By a News Reporter-Staff News Editor at Clinical Trials Week -- New research on Clinical Research is the subject of a report. According to news reporting out of Pulau Pinang, Malaysia, by NewsRx editors, research stated, "Nowadays, infrared thermographic inspection has increasingly been utilized for fault diagnosis tools of electrical equipment, because it maintains non-interrupting operation of power system and ensures early diagnosis of faults. The article discusses the performance comparison of multilayer perceptron (MLP) networks using various backpropagation algorithms for thermal imaging-based condition monitoring of electrical hotspots."

Our news journalists obtained a quote from the research from the University of Science Malaysia, "The training algorithms are Levenberg-Marquardt, Broyden-Fletcher-Goldfarb-Shanno quasi-Newton, resilient backpropagation, gradient descent with momentum and adaptive learning rate and standard gradient descent training algorithms. The performance of the training algorithms are evaluated in terms of percentage of accuracy, sensitivity, specificity, false-positive and false-negative results. In the beginning, thermal images of electrical equipment are captured using infrared camera. Six statistical intensity features, namely mean, maximum, minimum, median, standard deviation and variance extracted from each hotspot of equipment thermal image are used as the inputs of multilayered perceptron networks to classify the thermal conditions of hotspots into two classes, namely normal and defective."

According to the news editors, the research concluded: "The comparison of MLP networks using training algorithms proves that the MLP network trained with resilient backpropagation algorithm gives the best performance in thermal condition recognition."
