Imbalanced Low-Rank Tensor Completion via Latent Matrix Factorization

This paper proposes an imbalanced low-rank tensor completion method using latent tensor ring components and proximal alternating minimization, achieving better results with less computational cost.

Main Functions

  • src/trfold.m: Implements the tensor ring folding method.
  • src/trunfold.m: Implements the tensor ring unfolding method.
  • src/TRLMF_PAM.m: Implements the imbalanced low-rank tensor completion method based on the proximal alternating minimization algorithm.

Usage

An example is provided in the test_TRLMF_color_image.m file, demonstrating how to use the above functions for tensor completion. Running this file will show a comparison of the original image, the observed image, and the recovered image.
