分组数据的高斯过程回归

Gaussian Process Regression for Binned Data

University of Sheffield(谢菲尔德大学)

摘要:

许多数据集都是以分箱数据表的形式出现的。对这些数据执行回归通常涉及读取箱高度,忽略来自相邻箱的数据或在箱之间进行插值,从而高估或低估真实箱积分。在本文中,我们提出了一个优雅的方法进行高斯过程(GP)回归给定这样的装箱数据,允许一个潜在的功能,产生的装箱数据的概率预测。我们看几个应用程序。第一,用于差分私有回归;第二,对其他积分进行预测;第三,当输入区域是不规则形状的多面体集合时。总之,我们的方法提供了一种分析分箱数据的有效方法,这样人们就可以使用直方图表示中的更多信息,从而重建更有用和更精确的密度来进行预测。

英文摘要:

Many datasets are in the form of tables of binned data. Performing regression on these data usually involves either reading off bin heights, ignoring data from neighbouring bins or interpolating between bins thus over or underestimating the true bin integrals. In this paper we propose an elegant method for performing Gaussian Process (GP) regression given such binned data, allowing one to make probabilistic predictions of the latent function which produced the binned data. We look at several applications. First, for differentially private regression; second, to make predictions over other integrals; and third when the input regions are irregularly shaped collections of polytopes. In summary, our method provides an effective way of analysing binned data such that one can use more information from the histogram representation, and thus reconstruct a more useful and precise density for making predictions.
