Forecasting Covid-19 Time Series Data using the Long Short-Term Memory (LSTM)

Abstract

Confirmed statistical data of Covid-19 cases that have accumulated sourced from (https://corona.riau.go.id/datastatistik/) in Riau Province on June 7, 2021, there were 63441 cases, on June 14, 2021, it increased to 65883 cases, on June 21, 2021, it increased to 67910, and on June 28, 2021, it increased to 69830 cases. Since the beginning of this pandemic outbreak, it has been observed that the case data continues to increase every week until this July. This study predicts cases of Covid-19 time series data in Riau Province using the LSTM algorithm, with a dataset of 64 lines. Long-Short Term Memory has the ability to store memory information for patterns in the data for a long time at the same time. Tests predicting historical data for Covid-19 cases in Riau Province resulted in the lowest RMSE value in the training data, which was 8.87, and the test data, which was 13.00, in the death column. The evaluation of the best MAPE value in the training data, which is 0.23%, is in the recovered column, and the evaluation of the best MAPE value in the test data, which is 0.27%, in the positive_number column. In the test to predict the next 30 days using the LSTM model that has been trained, it was found that the performance evaluation of the prediction results for the positive_number column and the death column was very good, the recovery column was categorized as good, the independent_isolation column and the care_rs column were categorized as poor.

Deep Learning With Processing Algorithms for Forecasting Tourist Arrivals

“…Monthly tourist arrival data is used and combined with search data in GT. The DL method is currently popularly used in all fields, including medicine and nursing [24] , the field of forecasting the COVID-19 that has recently hit the world [25] , and the areas of smart city development that are currently popular are discussed in [40] .…”

Forecasting Tourist Arrivals with Partial Time Series Data Using Long-Short Term Memory (LSTM)

“…Because of the importance of forecasting, various studies on forecasting have been carried out. There are several studies related to forecasting that researchers including Forecasting demand for medical services have carried out (Huang et al, 2020) , Forecasting in US national parks for campground demand (Rice et al, 2019) , Forecasting cases of COVID-19 (Mukhtar et al, 2022) , (Santoso et al, 2021) . Forecasting the use of electrical loads (Bouktif et al, 2018) , and other forecasting.…”
