Abstract

fetched live from OpenAlex

In recent years, tensor completion problem, as a higher order generalization of matrix completion, has received much attention from scholars engaged in computer vision, data mining, and neuroscience.The problem is often solved by convex relaxation, which minimizes the tensor nuclear norm instead of the n-rank of the tensor.However, tensor nuclear minimizes all the singular value at the same level, which is unfair to large singular values.To solve the problem, this paper defines a log function of tensor, and uses it as an approximation of tensor rank function.Then, a simple yet efficient log-based algorithm for tensor completion (Log-TC) was proposed to recover an underlying low n-rank tensor.The Log-TC was verified through experiments on randomly generated tensors and color image inpainting, in comparison with two tensor completion algorithms: fixed point iterative method for low-rank tensor completion (FP-LRTC) and fast low rank tensor completion algorithm (FaLRTC).The results show that our algorithm greatly outperformed the two contrastive methods.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
