1. A method for determining a localized service quality in a wireless network, 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; and determining, via the processor, the localized service quality by applying a folding mechanism across the plurality of two dimensional matrices.
