Sharing-Aware Horizontal Partitioning for Exploiting Correlations During Query Processing
Optimization of join queries based on average selectivities is suboptimal in highly correlated databases. In such databases, relations are naturally divided into partitions, each ...

Comparison of Combination Methods using Spectral Clustering Ensembles
We address the problem of the combination of multiple data partitions, that we call a clustering ensemble. We use a recent clustering approach, known as Spectral Clustering, and th...

Allocation of Partitioned Data by Using A Neural Network Based Approach
In this paper, we investigate allocation of data partitions in the network for data objects that are partitioned by using secret sharing schemes [12] or erasure coding schemes [11...

Finding Consistent Clusters in Data Partitions
Abstract. Given an arbitrary data set, to which no particular parametrical, statistical or geometrical structure can be assumed, different clustering algorithms will in general pr...

Robust Data Clustering
We address the problem of robust clustering by combining data partitions (forming a clustering ensemble) produced by multiple clusterings. We formulate robust clustering under an ...
