Reverse Transcription-Polymerase Chain Reaction (RT-PCR) is the gold-standard test for the diagnosis of COVID-19. However, the RT-PCR test suffers from high false-negative rates and delayed results. Medical imaging, particularly Computed Tomography (CT) scans, has been recommended by the World ...
This study “confirmed” the view that depression rates are universally higher in women, and that biological determinants, sex role changes, but also unspecified social factors might contribute to this difference [59]. One survey showed women experienced higher levels of psychological distress, and an...
It is possible to see that for the properties obtained from MobilNetv2, the performance rates obtained with SVM are higher than the performance rates obtained with kNN. For this dataset, a high performance rate of 99.37% was obtained for both GridSearchCV and Bayesian kNN in the classification...
Sensitivity is the rate of true positives, and specificity is the rate of true negatives, and these rates will not necessarily be the same. Therefore, accuracy is another important analytical parameter that measures the rate of correct results for a certain test, expressed in percentage. Usually ...
6a and b, the accuracy rates are exactly the opposite (The hyperparameter settings for the experiments are the same). This phenomenon is a result of the random sampling. It indicates that the performance of the model is not enhanced by the mixup due to the data being already rich enough....
In response to the coronavirus disease 2019 (COVID-19) pandemic, the Chinese government implemented the dynamic COVID-zero strategy. We hypothesized that pandemic mitigation measures might have reduced the incidence, mortality rates, and case fatality ratios (CFRs) of the human immunodeficiency virus...
The SER module can assign more weights to more important channels and mitigate the problem of gradient disappearance, the ASPP module can obtain context information by atrous convolution using various sampling rates. In addition, the generalized dice loss (GDL) can reduce the correlation between ...
The coronavirus disease (COVID-19) pandemic has increased the necessity of immediate clinical decisions and effective usage of healthcare resources. Currently, the most validated diagnosis test for COVID-19 (RT-PCR) is in shortage in most developing countries, which may increase infection rates and...
Recent Global Patterns in Prostate Cancer Incidence and Mortality Rates. Eur. Urol. 2020, 77, 38–52. [Google Scholar] [CrossRef] Sud, A.; Jones, M.E.; Broggio, J.; Loveday, C.; Torr, B.; Garrett, A.; Nicol, D.L.; Jhanji, S.; Boyce, S.A.; Gronthoud, F.; et al. ...
Here, 𝛽1β1 and 𝛽2β2 are the decay rates of the gradients, typically set to 𝛽1=0.9β1=0.9 and 𝛽2=0.999β2=0.999. These decay rates control the exponential moving averages and help the optimizer to remain regulated and unbiased. To mitigate the bias introduced by the initiali...
