摘要：
Described herein are methods and systems for clustering events in temporal signals, such as physiological signals. In some embodiments, a method for identifying events of interest from noisy physiological signal data is provided, the method comprising: receiving physiological signal data； generating filtered signal using a filter defined by a spectral band； generating signal peak data by identifying, for each of a plurality of time windows, a signal peak in the filtered data； grouping waveforms corresponding to the time windows based on the signal peak data to generate clustered event data； determining parameters for a noise beta distribution； identifying a cluster of waveforms that does not fall within the noise beta distribution； generating a graphical representation based on the waveforms in the cluster； and displaying the graphical representation.
