To predict medium-range temperature with appreciable accuracy this study has been undertaken. We have tried to predict max-min temperature time series (signal) 5, 7 and 9 days ahead with the help of a new machine learning (neurocomputing) technique. Variational Mode Decomposition (VMD) has been used to decompose temperature time series and decomposed modes obtained from VMD have been individually used as input to Long Short Term Memory (LSTM). The LSTM predicted the modes individually and predicted modes are combined to generate the predicted signal. The signal predicted by this method closely matches with the actual test signal and minimizes the error in predicting the signal.
