Abstract
Online learning of model parameters is performed by obtaining a first target value in a target sequence and a feature vector corresponding to the first target value. The feature vector includes a plurality of elements. The feature vector can be modified to obtain a modified feature vector by reducing an absolute value of at least one element of the feature vector. An inverse Hessian matrix can be generated recursively from a previous inverse Hessian matrix using at least the feature vector and the modified feature vector. Parameters of a model can be updated using the inverse Hessian matrix.
