Abstract
An iterative exponential moving average algorithm generates a smoothed output data stream from a noisy input data stream. A smoothing factor used in calculating the exponential moving average is updated with each iteration of the exponential moving average algorithm based on a cumulative vote value, which is based, at least in part, on an estimated state of the input data stream.
