An Adaptive Rank-Based Tensor Ring Completion Model for Intelligent Transportation Systems
Bibliographic record
Abstract
Low rank tensor ring based data recovery algorithms have been widely used in vehicle road cooperation intelligent transportation system to recover missing data entries in the sensing data pre-processing stage. However, the existing tensor ring decomposition based methods often resolve the low rank optimization with predefined ranks, which often leads over-fitting when the selected rank is large. To overcome this challenge, we propose a Bayesian inference based tensor ring completion method which can automatically learn an optimal rank for the tensor ring completion. In this work, a likelihood Statistical model is firstly developed for low rank tensor ring approximation, and we impose a hierarchical sparse induced prior on the forward and horizontal slices of the kernel factor. Then, the Variational Bayesian algorithm is used to derive the parameters in the model, and the tensor ring rank can be achieved by gradually pruning the sparse horizontal and forward slice components in the factor. Finally, to elevate the proposal, numerous experiments have been conducted on two different intelligent transportation datasets, and the experimental results show that the proposed method can get the state-of-the-art performance in terms of recovery accuracy.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
