中文摘要	Because of the limitations of matrix factorization, such as losing spatial structure information, the concept of low-rank tensor factorization (LRTF) has been applied for the recovery of a low dimensional subspace from high dimensional visual data. However, existing methods often fail to tackle the real data which are corrupted by the noise with unknown distribution. In this paper, we propose a novel noise model to the tensor case for the LRTF task to overcome the drawbacks of existing models. This procedure treats the target data as high-order tensor directly and models the noise by a Mixture of Gaussians and a Markov Random Field, which is called MoG WLRTF MRF. The parameters in the model are estimated under the variational EM framework. Extensive experiments demonstrate the effectiveness of our method compared with other competing methods.
