A Comparison of Machine Learning Algorithms for Predicting Sea Surface Temperature in the Great Barrier Reef Region
- 用随机森林和XGBoost等集成方法提升海温预测精度
- XGBoost在误差指标上优于其他模型，尤其在概率分布匹配上表现最佳
- 适合关注海洋生态监测与气候建模的研究者参考
预测大堡礁区域海表温度（SST）对保护脆弱生态系统至关重要。本研究系统比较了岭回归、LASSO、随机森林和极端梯度提升（XGBoost）等机器学习算法的性能。结果表明，虽然LASSO和岭回归表现良好，但随机森林和XGBoost显著更优，其均方误差（MSE）、平均绝对误差（MAE）和均方根预测误差（RMSPE）更低。此外，XGBoost在最小化Kullback-Leibler散度（KLD）方面表现最优，说明其预测的概率分布更贴近实际观测。研究证实，集成方法尤其是XGBoost，在海温预测中具有高效性，可为气候与环境建模提供有力工具。
原文摘要 · Abstract (English)
Predicting Sea Surface Temperature (SST) in the Great Barrier Reef (GBR) region is crucial for the effective management of its fragile ecosystems. This study provides a rigorous comparative analysis of several machine learning techniques to identify the most effective method for SST prediction in this area. We evaluate the performance of ridge regression, Least Absolute Shrinkage and Selection Operator (LASSO), Random Forest, and Extreme Gradient Boosting (XGBoost) algorithms. Our results reveal that while LASSO and ridge regression perform well, Random Forest and XGBoost significantly outperform them in terms of predictive accuracy, as evidenced by lower Mean Squared Error (MSE), Mean Absolute Error (MAE), and Root Mean Squared Prediction Error (RMSPE). Additionally, XGBoost demonstrated superior performance in minimizing Kullback- Leibler Divergence (KLD), indicating a closer alignment of predicted probability distributions with actual observations. These findings highlight the efficacy of using ensemble methods, particularly XGBoost, for predicting sea surface temperatures, making them valuable tools for climatological and environmental modeling.
