With the growing ability to collect large volumes of volcano seismic data, the detection and labeling process of these records is increasingly challenging.Clearly, analyzing all available data through manual inspection is no longer a viable option.Supervised machine learning models might be considered to automatize the analysis of data acquired by in situ monitoring stations.However, the direct application of such algorithms is defiant, given the high complexity here of waveforms and the scarce and often imbalanced amount of labeled data.
In light of this and motivated by the wide success that generative adversarial networks (GANs) have seen at generating images, we present ESeismic-GAN, a GAN model to generate the magnitude frequency response of volcanic events.Our experiments demonstrate that ESeismic-GAN learns to generate the frequency components old taylor whiskey 1933 price that characterize long-period and volcano-tectonic events from Cotopaxi volcano.We evaluate the performance of ESeismic-GAN during the training stage using Fréchet distance, and, later on, we reconstruct the signals into time-domain to be finally evaluated with Frechet inception distance.
