摘要翻译：
在这项工作中，我们引入了一种混合GPs来解决数据关联问题，即根据产生它们的源来标记一组观测数据。与以前提出的几种GP混合物不同，新的混合物具有不使用门控函数来确定样品和混合物组分的关联的显著特点。相反，混合中的所有GPs都是全局的，样本按照输入空间的“轨迹”进行聚类。我们使用一种非标准变分贝叶斯算法来有效地恢复样本标签和学习超参数。我们展示了如何消除多目标跟踪问题的歧义，也探讨了模型在传统回归设置中的特点。

英文摘要：
  In this work we introduce a mixture of GPs to address the data association problem, i.e. to label a group of observations according to the sources that generated them. Unlike several previously proposed GP mixtures, the novel mixture has the distinct characteristic of using no gating function to determine the association of samples and mixture components. Instead, all the GPs in the mixture are global and samples are clustered following "trajectories" across input space. We use a non-standard variational Bayesian algorithm to efficiently recover sample labels and learn the hyperparameters. We show how multi-object tracking problems can be disambiguated and also explore the characteristics of the model in traditional regression settings.
