Determining meteorological factors influencing dengue cases in the National Capital Region using machine learning algorithms
Abstract
We use Principal Component Regression (PCR) and Random Forest Regression (RFR) models to identify the meteorological factors most influential on weekly DENV cases from 2009 to 2019 in the National Capital Region. The dataset split into a training set and a test set with an optimal ratio of 70% and 30%, respectively. The training set is utilize to train both the PCR and RFR models. In both the PCR and RFR models, maximum temperature, rainfall, minimum temperature, and relative humidity were identified as the top four important features influencing DENV cases, thereby enhancing mosquito reproduction and survival rates, and consequently increasing DENV cases. Additionally, wind direction ranked as the least important in both models. Moreover, the RFR outperformed the PCR, explaining 60.4% of the variability in DENV cases using meteorological factors.
