摘要

洪水是一种最具破坏性的灾难,影响到人、地方和生命。由于数据可用性的复杂性,洪水预测一直是一项具有挑战性的任务。传统的灾害管理模式依赖于卫星图像和雷达结果。它需要大量的时间来处理。机器学习为这个水文问题的新视角铺平了道路。机器学习(ML)和信息通信技术(ICT)的最新发展导致了最先进的实施和预测。这项工作的主要目标是通过比较逻辑回归、决策树、朴素贝叶斯和支持向量机分类器,识别出最准确的机器学习模型来识别洪水的发生。使用精度、召回率、f1分数、RMSE和准确性指标来评估机器学习策略。这些策略分别应用于单特征数据集、三特征数据集和四特征数据集。定量评价结果表明,决策树算法最适合洪水预测,其特征数量呈指数增长。

Comparative Analysis of Various Machine Learning Techniques for Flood Prediction
A flood is a most destructive disaster that affects people, places, and lives. Due to the complication in data availability, flood prediction is always a challenging task. The conventional mode of disaster management relies on satellite images and radar outcomes. It takes enormous time for processing. Machine learning paved the way for a new perspective on this hydrological problem. Recent developments in Machine Learning (ML) and Information and Communication Technology (ICT) have led to a state-of-the-art implementation and prediction. The major objective of this work is to recognize the most accurate machine learning model to identify flood occurrence, by comparing Logistic regression, Decision Tree, Naive Bayes, and Support Vector Machines classifiers. Machine Learning strategies are evaluated using precision, recall, F1-score, RMSE, and accuracy metrics. All the strategies are applied to one-feature dataset, three-feature dataset and four-feature dataset. The quantitative evaluation demonstrates that decision tree algorithm is most suitable for flood prediction and it exponentially grows with respect to the number of features examined.
