Abstract |
Wave height prediction is crucial in the marine sector and has wide-ranging applications, including determining the optimal route for autonomous ships, installing and operating wave power generators, and deploying offshore platforms. In the past, wave prediction was primarily based on numerical models grounded in physical principles; however, these methods require extensive computational resources. Recently, many researchers have applied machine learning methods to overcome these limitations. In this study, we utilized ensemble learning, a type of machine learning approach, to predict wave heights based on data collected from ocean observation stations in Korea. After determining the input variables of the model through correlation analysis, we applied and compared models using both bagging and boosting ensemble methods. The results indicated that, among the ensemble learning models, the boosting models outperformed the bagging models. This study is limited by its reliance on data from a single observation station. Therefore, future work will involve conducting research using data from multiple observation stations across various sea areas to validate the generalizability of the proposed model. |
