Since the COVID-19 pandemic, several research studies have proposed Deep Learning (DL)-based automated detection, reporting high cross-validation accuracy when classifying patients from normal or other common Pneumonia. Although reported outcomes are very in most cases, these results were obtained without an independent test set a separate data source(s). DL models likely to overfit training distribution sets not utilized prone learn dataset-specific artifacts rather than actual disease...

Mammography is the most widely used gold standard for screening breast cancer, where mass classification a prominent step. Classification of in is, however, an arduous problem as they usually have large variations terms shape, size, boundary, and texture. In this study, process automated with use transfer learning Deep Convolutional Neural Networks (DCNN) to extract features, bagged decision tree feature selection, finally Support Vector Machine (SVM) classifier classifying non-mass tissue....

ABSTRACT A large number of studies in the past months have proposed deep learning-based Artificial Intelligence (AI) tools for automated detection COVID-19 using publicly available datasets Chest X-rays (CXRs) or CT scans training and evaluation. Most these report high accuracy when classifying patients from normal other commonly occurring pneumonia cases. However, results are often obtained on cross-validation without an independent test set coming a separate dataset biases such as two...

Stress is the non-specific response of human brain which changes according to demand day life. In this paper stress and relaxation identified from activation alpha ( α) beta β) EEG bands depending on their power spectral density (PSD). occurs due sustained mental task in a test (Bengali, English, Math) environment work has been performed Reading, Writing Mathematical problem-solving stages. When β/α ratio 1.5 or more it indicates stress. The estimated taking PSD at different time interval...
