Exponential Smoothing is one of the commonly used methods for time series forecasting, based on the theoretical foundation of trend extrapolation. It assumes that quantitative evolution characteristics of phenomena within a certain future period will not deviate from past development trends. The forecast value is a weighted sum of all previous observations, with different weights assigned to different data points - more recent data receives higher weights while older data receives lower weights. This method can be implemented using recursive formulas where the smoothing parameter α controls the weight decay rate.
