Fig. 12From: Improving the accuracy of polar motion prediction using a hybrid least squares and long short-term memory modelAbsolute errors (AE) of the PMX and PMY prediction from 2011 to 2021, and all outcomes with the unit [as]. All results are based on 10-year time series of IERS EOP 14C04, using the LS + AR, LSTM, and LS + LSTM models, respectively. The MAE of Bulletin A relies on the PM prediction, coming from the IERS RS/PCBack to article page
