Abstract

In this study, I compared the predictive capability of five machine learning models (logistic regression (LR), multilayer perceptron (MLP), support vector machine (SVM), k-nearest neighbor (KNN), and random forest (RF)), and used the best-performed model to construct a susceptibility map for west central Florida. A total of 9 layers were extracted from the collected data and employed as conditional factors for the correlation analysis. Factors with negligible contribution to the quality of predictions, according to the information gain ratio technique, were later discarded. The validation of the machine learning models, performed using different statistical indices and receiver operating characteristic (ROC) curves, revealed that the RF model has the highest prediction, and thus was used for constructing a susceptibility map. The susceptibility map was divided into two levels (high susceptibility (H) and low susceptibility (L)), and the result was verified by Root Mean Squared Error (RMSE) and Confusion Matrix.
