WebLOESS or LOWESS smoothing ( LOcally WEighted Scatterplot Smoothing) is a technique to smooth a curve, thus removing the effects of noise. Take a local neighbourhood of the data. Fit a line (or higher-order polynomial) to that data. Pay more attention to the points in the middle of the neighbourhood ( weighting ).
