Query: Correlated Differential Privacy: Feature Selection in Machine Learning   Privacy preserving in machine learning is a crucial issue in industry
informatics since data used for training in industries usually contain
sensitive information. Existing differentially private machine learning
algorithms have not considered the impact of data correlation, which may lead
to more privacy leakage than expected in industrial applications. For example,
data collected for traffic monitoring may contain some correlated records due
to temporal correlation or user correlation. To fill this gap, we propose a
correlation reduction scheme with differentially private feature selection
considering the issue of privacy loss when data have correlation in machine
learning tasks. %The key to the proposed scheme is to describe the data
correlation and select features which leads to less data correlation across the
whole dataset. The proposed scheme involves five steps with the goal of
managing the extent of data correlation, preserving the privacy, and supporting
accuracy in the prediction results. In this way, the impact of data correlation
is relieved with the proposed feature selection scheme, and moreover, the
privacy issue of data correlation in learning is guaranteed. The proposed
method can be widely used in machine learning algorithms which provide services
in industrial areas. Experiments show that the proposed scheme can produce
better prediction results with machine learning tasks and fewer mean square
errors for data queries compared to existing schemes.
