摘要:

机器学习面临的一个主要挑战是在尊重个人隐私的同时增加数据的可用性。在这里,我们将差分隐私框架的可证明隐私保证与高斯过程(GP)的灵活性相结合。我们提出了一种使用GP提供差分私有(DP)回归的方法。然后,我们通过精心设计DP噪声协方差结构来改进这种方法,以有效地保护训练数据,同时最大限度地减少添加噪声的规模。我们发现,这种伪装方法实现了最大的准确性,同时仍然提供隐私保证,并提供了实用的DP回归多维输入。这些方法一起提供了一个入门工具包,用于结合差分隐私和GPS。

英文摘要:

A major challenge for machine learning is increasing the availability of data while respecting the privacy of individuals. Here we combine the provable privacy guarantees of the differential privacy framework with the flexibility of Gaussian processes (GPs). We propose a method using GPs to provide differentially private (DP) regression. We then improve this method by crafting the DP noise covariance structure to efficiently protect the training data, while minimising the scale of the added noise. We find that this cloaking method achieves the greatest accuracy, while still providing privacy guarantees, and offers practical DP for regression over multi-dimensional inputs. Together these methods provide a starter toolkit for combining differential privacy and GPs.
