초록본문(Abstract) | Recent advances in deep generative models resulted in general purpose tools for laypeople such as ChatGPT and Midjourney. In this talk, we present a waveform generative model specialized for professional-level tasks in earthquake sensing: a data-driven method to generate site-specific seismic wave measurement signals when no earthquake events are recorded. To achieve seismological realism in generated samples, we deploy unconditional WGAN-GP (Wasserstein GAN with Gradient Penalty) training framework augmented with PPSD (Probabilistic Power Spectral Density) loss function. * This work is supported by the Korea Meteorological Administration Research and Development Program under Grant KM12021-01112. |
