摘要:

空间点过程可以用强度函数来表征,该强度函数预测在空间上发生的事件的数量。在本文中,我们开发了一种方法来推断预测强度间隔学习空间模型使用正则化的标准。我们证明了所提出的方法具有样本外预测性能保证,不像标准估计,是有效的,即使当空间模型是错误的。该方法是使用合成以及真实的空间数据。

英文摘要:

A spatial point process can be characterized by an intensity function which predicts the number of events that occur across space. In this paper, we develop a method to infer predictive intensity intervals by learning a spatial model using a regularized criterion. We prove that the proposed method exhibits out-of-sample prediction performance guarantees which, unlike standard estimators, are valid even when the spatial model is misspecified. The method is demonstrated using synthetic as well as real spatial data.
