Coronavirus emerged as a highly contagious, pathogenic virus that severely affects the respiratory system of humans. The epidemic-related data is collected regularly, which machine learning algorithms can employ to comprehend and estimate valuable information. The analysis of the gathered data through time series approaches may assist in developing more accurate forecasting models and strategies to combat the disease. This paper focuses on short-term forecasting of cumulative reported incidences and mortality. Forecasting is conducted utilizing state-of-the-art mathematical and deep learning models for multivariate time series forecasting, including extended susceptible-exposed-infected-recovered (SEIR), long-short-term memory (LSTM), and vector autoregression (VAR). The SEIR model has been extended by integrating additional information such as hospitalization, mortality, vaccination, and quarantine incidences. Extensive experiments have been conducted to compare deep learning and mathematical models that enable us to estimate fatalities and incidences more precisely based on mortality in the eight most affected nations during the time of this research. The metrics like mean absolute error (MAE), root mean square error (RMSE), and mean absolute percentage error (MAPE) are employed to gauge the model's effectiveness. The deep learning model LSTM outperformed all others in terms of forecasting accuracy. Additionally, the study explores the impact of vaccination on reported epidemics and deaths worldwide. Furthermore, the detrimental effects of ambient temperature and relative humidity on pathogenic virus dissemination have been analyzed.
冠状病毒是一种具有高度传染性的致病病毒,严重影响人类呼吸系统。与疫情相关的数据会定期收集,机器学习算法可以利用这些数据来理解和估计有价值的信息。通过时间序列方法对收集到的数据进行分析,可能有助于开发更准确的预测模型和抗击该疾病的策略。本文重点关注累计报告发病率和死亡率的短期预测。利用最先进的数学和深度学习模型进行多变量时间序列预测,包括扩展的易感-暴露-感染-康复(SEIR)模型、长短期记忆(LSTM)模型和向量自回归(VAR)模型来进行预测。通过整合住院、死亡、疫苗接种和隔离发病率等额外信息对SEIR模型进行了扩展。已经进行了广泛的实验,以比较深度学习模型和数学模型,使我们能够根据本研究期间受影响最严重的八个国家的死亡率更精确地估计死亡人数和发病率。使用平均绝对误差(MAE)、均方根误差(RMSE)和平均绝对百分比误差(MAPE)等指标来衡量模型的有效性。深度学习模型LSTM在预测准确性方面优于所有其他模型。此外,该研究还探讨了疫苗接种对全球报告的疫情和死亡的影响。此外,还分析了环境温度和相对湿度对致病病毒传播的不利影响。
