Before revision:  By "learning" URLanizing the subtle change of waveform morphology from large amounts of raw waveform data, unsupervised manifold learning can help delineate a high-dimensional structure . We hypothesize that the shape of this structure conveys inner dynamics information via the novel three-dimensional (3D) image.
After revision:  By "learning" URLanizing the subtle change of waveform morphology from large amounts of raw waveform data, unsupervised manifold learning can help delineate a high-dimensional structure and display it as a novel three-dimensional (3D) image.
