Also, it can be used to smooth the local discontinuities which emerge during the regression process in a recursive manner. 4.6.1 Noise Removal. The PD smoothing for noise removal is demonstrated by considering the noisy data shown in Fig. 4.23. It includes 10,000 data ... Exponential smoothing is a rule of thumb technique for smoothing time series data using the exponential window function. Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time. It is an easily learned and easily applied procedure for making some determination based on prior assumptions by the user, such as seasonality.
