Microseismic Signal Classification Based on Artificial Neural Networks

Figure 1

Classification steps of microseismic signals. The green, blue, brown-yellow, and wine red correspond to steps (1), (2), (3), and (4), respectively. (1) Set of inputs; (2) feature extraction, including statistical features, spectrum features, and waveform features; (3) training of ANN; (4) application of the classification model.
