Centroidal Voronoi Tessellation Based Proper Orthogonal Decomposition Analysis

Proper orthogonal decompositions (POD) have been used to systematically extract the most energetic modes while centroidal Voronoi tessellations (CVT) have been used to systematically extract best representatives. We combine the ideas of CVT and POD into a hybrid method for model reduction. The optimality of such an approach and various practical implementation strategies are discussed.
