Development of machine learning model for automatic ELM-burst detection without hyperparameter adjustment in KSTAR tokamak

In this study, a neural network model inspired by a one-dimensional convolution U-net is developed to automatically accelerate edge localized mode (ELM) detection from big diagnostic data of fusion devices and increase the detection accuracy regardless of the hyperparameter setting. This model recog...
