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.

Recursive Least-Squares (Split RLS) algorithm can perform the approximated RLS with O(N) complexity for signals having no special data structure to be exploited (e.g., the signals in multichannel adaptive filtering applications, which are not shifts of a single-channel signal data), while avoiding the high compu- tational complexity (0( N2)) required in the conventional RLS algorithms. The basic building block of adaptive recursive least square (ARLS) control algorithm is illustrated in Fig 11 with blue color coding.
