| Description: | In this article authors proposed a hybrid system in which the full covariance matrix is used only at the initial stage of learning. At the further stage of learning, the amount of covariance matrix increases significantly, which, combined with rounding errors, causes problems with matrix inversion. Therefore, when the number of matrices with a determinant of 0 exceeds 1%, the system goes into the model of diagonal covariance matrices. Thanks to this, the hybrid system has achieved a better result of about 11%. |
