AirCP

AirCP, standing for Auxiliary Information Regularized CP tensor completion, is a system for performing CP tensor completion with regularized trace of the auxiliary information. The Alternating Direction Method of Multipliers (ADMM) is applied to solve the whole optimization problem.

For details of the algorithm and implementation, see [1], and if you are interested in this direction of research you can check out our follow up work in [2].

Running

The implementation of AirCP has been tested on Matlab 2013. An example of running can be found in main.m. Matlab Tensor Toolbox is necessary and has been included in the package. Synthetic data can be generated with GenerateSyntheticData.m.
