Privacy-Preserving and Outsourced Multi-User k-Means ...

Many techniques for privacy-preserving data mining (PPDM) have been investigated over the past decade. Often, the entities involved in the data mining process are end-users or organizations with limited computing and storage resources. As a result, such entities may want to refrain from participating in the PPDM process. To overcome this issue and to take many other benefits of cloud computing ...

Aug 11, 2018· The k-means clustering is one of the most widely used techniques in data mining [11, 16, 2, 20, 15].The k-means clustering algorithm is used to find groups which have not been explicitly labeled in the data. This can be used to confirm business assumptions about what types of groups exist or to identify unknown groups in complex data sets.
