All imputation techniques either increased or decreased the data autocorrelation and with this affected the forecasting performance of the ARIMA and LSTM algorithms. The best imputation technique did not guarantee better predictions obtained on the imputed data. The mean imputation, LOCF, KNN, Stineman,...
Although traditional models like autoregressive integrated moving average (ARIMA), error-trend-seasonality (ETS), and neural networks (NN) have been proposed for predicting polarization current14, they grapple with challenges in terms of outlier sensitivity and effectively handling seasonality and trends....

The performance of optimized Bi-LSTM model is compared with the performance of traditional machine learning (ML) models such as support vector regression (SVR) and SVR polynomial {2nd and 3rd order}, Auto Regressive Integrated Moving Average (ARIMA) and ARIMAX (ARIMA with exogenous variables) and...
ARIMA is a technique for predicting time series data. We will show how to use it, and althouth ARIMA will not serve as our final prediction, we will use it as a technique to denoise the stock a little and to (possibly) extract some new patters or features. from statsmodels.tsa.arima...

Autoregressive Integrated Moving Average (ARIMA) - This was one of the most popular techniques for predicting future values of time series data (in the pre-neural networks ages). Let's add it and see if it comes off as an important predictive feature. Stacked autoencoders - most of the af...
