Real-Time Prediction of the Trend of Ground Motion Intensity Based on Deep Learning

Figure 9

Model application schematic. (a) The recorded time series of acceleration with zero padding at the beginning. The red dots represent the calculated Arias intensity ratio alpha for each second in the next 5 seconds and the previous 5 seconds. (b) The probability that the previous 30 seconds of recordings are sampled at each red dot on the left and input the model to determine whether the Arias intensity will increase or decrease in the future. The red line represents whether the intensity will actually increase from the known recordings, that is, the label. The label with alpha> 1 is 1, and the label with alpha <1 is 0.
