Kalman filter can be regarded as a special case of recursive least squares methods . Gama (typically between 0.98 and 1) is referred to as the “forgetting factor”. Recursive least square (RLS) with multiple forgetting factors accounts for different rates of change for different parameters and thus, enables simultaneous estimation of the time-varying grade and the piece-wise constant mass.
