WebExponential Smoothing. Exponential forecasting is another smoothing method and has been around since the 1950s. Where niave forecasting places 100% weight on the most recent observation and moving averages place equal weight on k values, exponential smoothing allows for weighted averages where greater weight can be placed on recent observations ... WebIF(RMS), RMS Forward Current IF(RMS) expresses a physical limit of the bond wires. This is because the heating of the wire is proportional to the square of the current.

WebIn this case, an RMSE of a few hundred is good enough. Now, to judge whether your SMSE of a few hundred is good or just a value of 1 is good is judged based upon the data mean. Hence, a term called scatter index (SI) is defined to judge whether RMSE is good or not. SI is RMSE normalised to the measured data mean or SI=RMSE/measured data mean.
