Chest radiography (X-ray) is a critical imaging modality for the diagnosis of thorax diseases. Automated classification chest X-rays has enormous potential to benefit diagnostic decision making. Most existing models are designed consider single-view X-ray image, mostly frontal view, failing utilize complementary information provided by lateral view when available. In clinical practice, radiologists often examine both and views gather more diagnosis. Thus, well-designed model should take...
Accurately estimating the state of charge a lithium-ion battery plays an important role in managing health and its charging state. Traditional state-of-charge estimation methods encounter difficulties processing diverse temporal data sequences predicting adaptive results. To address these problems, we propose spatial transformer network (STN) for multi-temperature batteries. The proposed STN consists convolutional neural with temporal–spatial module long short-term memory network, which...
