The optimizer used is Adadelta, an improved and extended version of the Adagrad algorithm. Compared with Adagrad, Adadelta no longer accumulates all past gradients, but adjusts the learning rate based on the moving window updated by the gradient, making it more robust [33]. The main parameters for setting the Adadelta algorithm include a learning rate of 1.0, a decay rate of 0.95 for the moving average of Adadelta gradient squares, a blur factor of 1×10-6, and a learning rate decay value of 0 after each parameter update.
