US Patent 12112254 Optimizing loss function during training of network

Some embodiments provide a method for training a machine-trained (MT) network. The method uses a set of training inputs to train parameters of the MT network according to an initial loss function. The method uses a set of validation inputs to compute an error measure for the MT network as trained by the first set of training inputs. The method modifies the loss function for subsequent training of the MT network based on the computed error measure. The method uses the set of training inputs to train the parameters of the MT network according to the modified loss function.
