Claim 0:
1. An earthquake event classification method using an attention-based neural network, the method comprising:
preprocessing input earthquake data by centering;
extracting a feature map by nonlinearly converting the preprocessed earthquake data through a plurality of convolution layers having three or more layers;
measuring an importance value of a learned feature of the nonlinear-converted earthquake data based on an attention technique in which interdependence between channels of the feature map is modeled;
correcting a feature value of the measured importance value through element-wise multiply with the learned feature map;
performing down-sampling through max-pooling based on the corrected feature value; and
classifying an earthquake event by regularizing the down-sampled feature value.
