The pith
Transformed tensor SVD with non-Fourier unitary transforms yields higher PSNR in robust tensor completion than Fourier-based methods.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Robust tensor completion is performed using transformed tensor singular value decomposition that employs unitary transform matrices. A lower tubal rank tensor can be obtained by using other unitary transform matrices than that by using discrete Fourier transform matrix. This leads to better recovery performance measured in PSNR on hyperspectral, video and face datasets compared to Fourier transform and other methods.
What carries the argument
Transformed tensor SVD, which applies arbitrary unitary transform matrices instead of the discrete Fourier transform matrix to produce a lower-tubal-rank representation for completion.
Load-bearing premise
A lower tubal rank tensor can be obtained by using other unitary transform matrices than that by using discrete Fourier transform matrix.
What would settle it
Direct numerical comparison on the same hyperspectral, video, and face datasets showing that the PSNR of the transformed-SVD method is not higher than the Fourier-transform baseline.

read the original abstract
In this paper, we study robust tensor completion by using transformed tensor singular value decomposition (SVD), which employs unitary transform matrices instead of discrete Fourier transform matrix that is used in the traditional tensor SVD. The main motivation is that a lower tubal rank tensor can be obtained by using other unitary transform matrices than that by using discrete Fourier transform matrix. This would be more effective for robust tensor completion. Experimental results for hyperspectral, video and face datasets have shown that the recovery performance for the robust tensor completion problem by using transformed tensor SVD is better in PSNR than that by using Fourier transform and other robust tensor completion methods.

Referee Report
Summary. The paper proposes robust tensor completion via transformed tensor SVD, replacing the standard discrete Fourier transform with other unitary transform matrices. The central motivation is that non-DFT unitary transforms yield tensors of lower tubal rank, which in turn improves recovery performance. Experiments on hyperspectral, video, and face data report higher PSNR than Fourier-based tensor methods and other robust completion baselines.
Significance. If the rank-reduction premise is verified and the PSNR gains are shown to arise from it rather than tuning or implementation details, the work would offer a simple, parameter-light way to improve tensor completion by transform choice. The absence of any reported tubal-rank tables or direct comparisons, however, leaves the claimed mechanism untested and limits the result's immediate impact.
major comments (2)
- [Abstract / Experiments] Abstract and experimental results section: the motivating claim that 'a lower tubal rank tensor can be obtained by using other unitary transform matrices' is never tested; no table or figure reports the tubal ranks (or their comparison) under DFT versus the chosen transforms (e.g., DCT) on the evaluated datasets. Without this measurement the observed PSNR gains cannot be attributed to the stated mechanism.
- [Method / Experiments] Method and experimental sections: the paper supplies no description of how the unitary transform matrix is selected for each dataset, nor any ablation on transform choice, error bars, or statistical significance of the PSNR differences. These omissions make it impossible to assess whether the reported improvements are robust or reproducible.
minor comments (1)
- [Preliminaries] Notation for the transformed SVD and the definition of tubal rank should be stated explicitly with equation numbers rather than left to the reader to infer from prior tensor-SVD literature.
Simulated Author's Rebuttal
We thank the referee for the constructive comments. We agree that direct verification of the tubal-rank reduction and additional experimental details are needed to strengthen the manuscript. We address each point below and will incorporate the suggested changes in the revision.

Referee: [Abstract / Experiments] Abstract and experimental results section: the motivating claim that 'a lower tubal rank tensor can be obtained by using other unitary transform matrices' is never tested; no table or figure reports the tubal ranks (or their comparison) under DFT versus the chosen transforms (e.g., DCT) on the evaluated datasets. Without this measurement the observed PSNR gains cannot be attributed to the stated mechanism.
Authors: We acknowledge that the current manuscript does not report explicit tubal-rank values or comparisons across transforms. In the revised version we will add a table (or supplementary figure) listing the tubal ranks obtained with the DFT and the selected unitary transforms on each of the hyperspectral, video, and face datasets. This addition will directly test the motivating claim and allow readers to assess whether the observed PSNR improvements are consistent with the rank-reduction mechanism. revision: yes

These omissions make it impossible to assess whether the reported improvements are robust or reproducible.
Authors: We agree that the selection procedure, ablation results, and statistical details are missing. In the revision we will (i) describe how the unitary transform is chosen for each dataset, (ii) include an ablation study comparing several candidate transforms, (iii) report error bars from multiple independent runs, and (iv) add statistical significance tests (e.g., paired t-tests) on the PSNR differences. These changes will make the experimental claims more reproducible and robust. revision: yes
Circularity Check
No significant circularity; algorithmic proposal validated empirically.
full rationale
The paper presents transformed tensor SVD as a methodological variant of tensor SVD for robust completion, with the motivation stated as an empirical premise about tubal rank rather than a derived claim. No equations, parameters, or results are shown to reduce by construction to fitted inputs, self-definitions, or self-citation chains. Performance assertions rest on direct experimental comparisons (PSNR on hyperspectral/video/face data) against baselines, making the chain self-contained without circular reductions. Absence of explicit tubal-rank tables is an evidentiary gap but does not create definitional or fitted-input circularity.
