Extreme learning machines have gained a lot of attention by the machine learning community because of its interesting properties and computational advantages. With the increase in collection of information nowadays, many sources of data have missing information making statistical analysis harder or unfeasible. In this paper, we present a new model, coined spatial extreme learning machine, that combine spatial modeling with extreme learning machines keeping the nice properties of both methodologies and making it very flexible and robust. As explained throughout the text, the spatial extreme learning machines have many advantages in comparison with the traditional extreme learning machines. By a simulation study and a real data analysis we present how the spatial extreme learning machine can be used to improve imputation of missing data and uncertainty prediction estimation.
极限学习机因其有趣的特性和计算优势而受到机器学习界的广泛关注。随着当今信息收集量的增加,许多数据源存在缺失信息,这使得统计分析变得更加困难或不可行。在本文中,我们提出了一种新的模型,即空间极限学习机,它将空间建模与极限学习机相结合,保留了两种方法的优良特性,使其非常灵活且稳健。正如文中所解释的,与传统极限学习机相比,空间极限学习机具有许多优势。通过模拟研究和实际数据分析,我们展示了空间极限学习机如何用于改进缺失数据的插补和不确定性预测估计。
