Fig. 9From: Short-term prediction of celestial pole offsets with interpretable machine learningPrediction accuracy of NAMs in terms of µas for the dX and dY components separately. Two cases are presented: using two input features (\(\text {dX}\) and \(\text {dY}\)); four input features (\(\text {dX}\), \(\text {dY}\), \(\cos (\sigma _f t)\), and \(\sin (\sigma _f t)\)). The former are equivalent to the results presented in Fig. 3Back to article page
