Due to the complexity of wind speed, it has been reported that mixed-noise models, constituted by multiple noise distributions, perform better than single-noise models. However, most existing regression models suppose that the noise distribution is single. Therefore, we study the Least square S V R of the Gaussian-Laplacian mixed homoscedastic ( G L M - L S S V R ) and heteroscedastic noise ( G L M H - L S S V R ) for complicated or unknown noise distributions. The ALM technique is used to solve model G L M - L S S V R . G L M - L S S V R is used to predict short-term wind speed with historical data. The prediction results indicate that the presented model is superior to the single-noise model, and has fine performance.
由于风速的复杂性,据报道,由多个噪声分布构成的混合噪声模型比单噪声模型表现更好。然而,大多数现有的回归模型假设噪声分布是单一的。因此,针对复杂或未知的噪声分布,我们研究了高斯 - 拉普拉斯混合同方差(GLM - LSSVR)和异方差噪声(GLMH - LSSVR)的最小二乘支持向量回归。采用增广拉格朗日乘子法(ALM)技术求解模型GLM - LSSVR。利用GLM - LSSVR通过历史数据预测短期风速。预测结果表明,所提出的模型优于单噪声模型,具有良好的性能。
