Evaluating PhaseNet on Teleseismic Data with MsPASS
Researchers have developed a new workflow using the PhaseNet machine learning model to improve seismic wave detection on teleseismic data. This workflow, implemented with MsPASS, significantly enhances the recall of P-wave picks by over 700% compared to models trained on regional data. While increasing model size improved accuracy, it drastically reduced inference speed, suggesting GPUs are more suitable than CPUs for scaling this application. AI
