Epoch functions

class neuxus.nodes.epoch_function.UnivariateStat(input_port, stat, quantile=None, iqr_quantile=[None, None])

Mean, Variance, Median, etc. on the incoming epoched Signal perform calculation on each coming epoch and save last value in value attribute and update the output

Attributes:

• output (Port): signal output port

• value (float): last value calculated (on the last epoch come)

Args:

• input (Port): port of incoming epoched data

• stat (str):

• quantile (float between 0 and 1): default is None, used if stat is ‘quantile’, precise the quantile to calculate

• iqr_quantile (list of two float between 0 and 1): default is [None, None], used if stat is ‘iqr’, precise the limit of range

  Examples:

  UnivariateStat(Port18, 'mean')
  UnivariateStat(Port18, 'quantile', quantile=0.23)
  UnivariateStat(Port18, 'iqr', iqr_quantile=[0.23, 0.78])
  

class neuxus.nodes.epoch_function.Windowing(input_port, window)

Apply a windowing function to the input epohed signal

Attributes:

• output (Port): epoch output port

Args:

• input (Port): port of epoched incoming data

• window (str): to be choosen between [‘blackman’, ‘hanning’, ‘hamming’, ‘triang’]

Example:

Windowing(Port48, ‘blackman’)
