Improved Approximation Algorithms for Relational Clustering

Summary: Relational k-median and k-means clustering without join materialization. Relational k-median: first efficient relative-approximation; relational k-means: improved (1+ε)γ-approximation with faster runtime via fractional hyper-tree width fhw; runtime ~O(k^2 N fhw)+T_γ(k^2).
