1. A method for determining a localized service quality in a wireless network, the method comprising: constructing, via a processor, a tensor comprising a plurality of dimensions to represent data for the localized service quality in the wireless network; receiving, via the processor, data for the wireless network that is gathered at a coarse granularity level; populating, via the processor, the tensor in accordance with the data that is gathered at the coarse granularity level; applying, via the processor, an unfolding mechanism to construct a plurality of two dimensional matrices from the tensor; determining, via the processor, for each respective two dimensional matrix of the plurality of two dimensional matrices that is constructed an approximation for a pre-determined level of accuracy, and populating all entries of each respective two dimensional matrix that are not populated in accordance with the approximation of the respective two dimensional matrix, wherein the determining of the approximation for the pre-determined level of accuracy for a respective matrix of the plurality of two dimensional matrices comprises: identifying all Eigen values of the respective matrix using singular value decomposition and determining the approximation by applying a threshold; and selecting a first number of Eigen vectors in accordance with the pre-determined level of accuracy; and determining, via the processor, the localized service quality by applying a folding mechanism across the plurality of two dimensional matrices.
