Several machine learning and deep models were reported in the literature to forecast COVID-19 but there is no comprehensive report on comparison between statistical models. The present work reports a comparative time-series analysis of techniques (Recurrent Neural Networks with GRU LSTM cells) (ARIMA SARIMA) country-wise cumulative confirmed, recovered, deaths. Gated Recurrent Units (GRU), Long Short-Term Memory (LSTM) cells based (RNN), ARIMA SARIMA trained, tested, optimized trends COVID-19. We deployed python optimize parameters which include (p, d, q) representing autoregressive moving average terms model additional seasonal are denoted by (P, D, Q). Similarly, for RNN models' (number layers, hidden size, rate number epochs) deploying PyTorch framework. best was chosen lowest Mean Square Error (MSE) Root Squared (RMSE) values. For most data countries, learning-based outperformed models, an RMSE values that 40 folds less than But some countries (ARIMA, Further, we emphasize importance various factors such as age, preventive measures healthcare facilities etc. play vital role rapid spread pandemic.

This comprehensive overview focuses on the issues presented by pandemic due to COVID-19, understanding its spread and wide-ranging effects of government-imposed restrictions. The examines utility autoregressive integrated moving average (ARIMA) models, which are often overlooked in forecasting perceived limitations handling complex dynamic scenarios. Our work applies ARIMA models a case study using data from Recife, capital Pernambuco, Brazil, collected between March September 2020. research provides insights into implications adaptability predictive methods context global pandemic. findings highlight models’ strength generating accurate short-term forecasts, crucial for an immediate response slow down disease’s rapid spread. Accurate timely predictions serve as basis evidence-based public health strategies interventions, greatly assisting management. model selection involves automated process optimizing parameters autocorrelation partial plots, well various precise measures. performance chosen is confirmed when comparing forecasts with real reported after forecast period. successfully both recovered COVID-19 cases across preventive plan phases Recife. However, model’s observed extend future. By end period, error substantially increased, it failed detect stabilization deceleration cases. highlights challenges associated such under-reporting recording delays. Despite these limitations, emphasizes potential while emphasizing need further enhance long-term predictions.

A proficient approach to forecast COVID-19 spread via optimized dynamic machine learning models

Scientific Reports, Год журнала: 2022, Номер 12(1)

Опубликована: Фев. 14, 2022

This study aims to develop an assumption-free data-driven model accurately forecast COVID-19 spread. Towards this end, we firstly employed Bayesian optimization tune the Gaussian process regression (GPR) hyperparameters efficient GPR-based for forecasting recovered and confirmed cases in two highly impacted countries, India Brazil. However, machine learning models do not consider time dependency data series. Here, dynamic information has been taken into account alleviate limitation by introducing lagged measurements constructing investigated models. Additionally, assessed contribution of incorporated features prediction using Random Forest algorithm. Results reveal that significant improvement can be obtained proposed In addition, results highlighted superior performance GPR compared other (i.e., Support vector regression, Boosted trees, Bagged Decision tree, Forest, XGBoost) achieving averaged mean absolute percentage error around 0.1%. Finally, provided confidence level predicted based on showed predictions are within 95% interval. presents a promising shallow simple approach predicting
