"WebFisher information is a statistical technique that encapsulates how close or far some random instance of a variable is from its true parameter value. It may occur so that there are many parameter values on which a probability distribution depends. In that case, there is a different value for each of the parameters. " - Ewc fisher matrix

WebApr 13, 2024 · In essence, the R-EWC approach is an effective improvement of the typical EWC method. EWC tends to use the Fisher Information Matrix (FIM) to identify directions in feature space related to the important learned knowledge, and assumes that the Fisher Information Matrix can be always diagonal. WebFisher Information Matrix can be poor and steer EWC in directions that will forget task A. Right: after a suitable reparameterization (i.e., a rotation) the diagonal approximation is better and EWC can avoid forgetting task A. EWC is an elegant approach to selective regularization of network parameters when switching tasks. It uses the Fisher
