Holst Mathematics Autom. 1996 8 WebJul 1, 1993 · Introduction The idea of using the exponential forgetting factor '>-' to weight new data more heavily than the old data in the RLS estimation algorithm is well known. The purpose is to prevent the covariance updating equation becomes too small, so that the tracking capability of the RLS algorithm is preserved (Ljung and Soderstrom, 1987).
WebThe forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [1] A related concept is the strength of memory that …
