Query: Low-complexity Rank-Efficient Tensor Completion For Prediction And
  Online Wireless Edge Caching   Wireless edge caching is a popular strategy to avoid backhaul congestion in
the next generation networks, where the content is cached in advance at base
stations to serve redundant requests during peak congestion periods. In the
edge caching data, the missing observations are inevitable due to dynamic
selective popularity. Among the completion methods, the tensor-based models
have been shown to be the most advantageous for missing data imputation. Also,
since the observations are correlated across time, files, and base stations, in
this paper, we formulate the cooperative caching with recommendations as a
fourth-order tensor completion and prediction problem. Since the content
library can be large leading to a large dimension tensor, we modify the latent
norm-based Frank-Wolfe (FW) algorithm with towards a much lower time complexity
using multi-rank updates, rather than rank-1 updates in literature. This
significantly lower time computational overhead leads in developing an online
caching algorithm. With MovieLens dataset, simulations show lower
reconstruction errors for the proposed algorithm as compared to that of the
recent FW algorithm, albeit with lower computation overhead. It is also
demonstrated that the completed tensor improves normalized cache hit rates for
linear prediction schemes.
