“…After data preprocessing, ANN input parameters were selected from historical data. Many prediction papers selected the input based on the significance of the data from the autocorrelation function (ACF) (Flores et al, 2012;Sfetsos and Coonick, 2000). Fig.…”

“…The output layer has a single neuron with a multiplication unit. For all the methods, the number of significant inputs is calculated using the autocorrelation and partial autocorrelation of the series (Flores et al, 2012). The interested readers may go through (Flores et al, 2012) to have a detailed description on selection of significant inputs of ANN for univariate TSF using autocorrelation and partial autocorrelation functions.…”

“…For all the methods, the number of significant inputs is calculated using the autocorrelation and partial autocorrelation of the series (Flores et al, 2012). The interested readers may go through (Flores et al, 2012) to have a detailed description on selection of significant inputs of ANN for univariate TSF using autocorrelation and partial autocorrelation functions. We have considered 11 univariate time series datasets (as mentioned in Table 2) from the Time Series Data Library (Hyndman, 2010) for analysing the effectiveness of the proposed method with other methods.…”

“…where P (A|B) is the best linear projection of A on B. Although both AC and PAC functions measures linear correlation, they can still be used for feature selection of nonlinear prediction methods, such as neural network techniques, as discussed in [42]. Thus, PAC function is used here for feature lag selection.…”
