... and windowed segmentation. A hybrid model combining convolutional neural networks, bidirectional long short-term memory and dual attention mechanisms was used to extract spatiotemporal features for BP prediction. Findings Data from ten healthy subjects showed that, under the leave-one-subject-out...

... network is improved by embedding the global grouped coordinate attention mechanism module and the improved bidirectional feature pyramid network. Firstly, a data acquisition system was built using a MEMS-integrated PCG-ECG sensor to construct a private data set. Second is the time-frequency transformation...
