Data release is likely to result in privacy disclosure, so appropriate privacy protection measures are required for various data release technologies in order to ensure the privacy and safety of information, while differential privacy as a reliable model for privacy protection is extensively researched and applied. This paper presents the histogram data publishing solutions under differential p...

In order to solve the problem of privacy disclosure when publishing high-dimensional data and protect frequent itemsets in association rules, a method based on rules (PDP Growth) is proposed. This method, distributed framework, utilizes rough set theory improve mining rules. It optimizes analysis while reducing dimensionality data, eliminating more redundant attributes, obtaining concise itemse...

Abstract Protection of transmission lines is the most important defense against faults in multi-terminal HVDC system. Up until now, no single protection can balance operation speed and sensitivity needed for all fault types. To solve this problem, a novel current differential line proposed paper. The intrinsic properties are analyzed first. Then, essence ideal revealed fundamental relations bet...
