Predicting the Polish timescale UTC(PL) based on the corrections designated by the UTC and UTCr scale
Łukasz Sobolewski · 2013
The article presents the results of research on the prediction of the Polish timescale UTC(PL) based on the corrections designated according to UTC and UTCr scale. In both cases for prediction the GMDH neural networks and time series analysis method were used. For predicting the UTC(PL) the influence of the input data preparation method for the GMDH neural network was examined. The obtained results were compared with the predictions designated using linear regression method. Better results of predicting the UTC(PL) were obtained using GMDH neural network. The most preferred results have been obtained for the input data containing only the corrections designated by the UTCr scale.
