Accurate rainfall forecasts are important throughout Agriculture, Water Resources, and Disaster preparation. In this example, we use two complex devices study design, Logistic Regression and Random Forest classifier, to predict rainfall in Australia. The data set source for this study came from Kagle, which provides a complete summary of climate changes over time. The aim of our research is to develop a robust prediction model concerning possible precipitation types Australian territories. Logistic Regression provides a baseline model, while the Random Forest Classifier provides an ensemble based the technique improves accuracy. We look for the content engineering and hyperparameter tuning to improve the model performance. The results of this study are important for decision makers and stakeholders, as accurate rainfall forecasts can provide to strengthen resource management, risk reduction and sustainability planning in different areas. The results of our models is that it will contribute to a better understanding of Australian rainfall Patterns, therefore helps in effective decision making and preparation.
