Abstract
We comment on a paper describing an algorithm for image set classification. Following the general practice in computer vision research, the performance of the algorithm was evaluated on benchmarks in order to support the claim of its advantage over other algorithms in the literature. We have examined the reported data of experiences on two datasets, and found that many numbers are not a possible answer regardless how the random partitions were selected and regardless how the algorithms performed in each partition. Our finding suggests that the experimental results in the paper ("Deep Reconstruction Models for Image Set Classification", IEEE Trans. Pattern Analysis and Machine Intelligence, vol. 37, no. 4, pp. 713-727, April 2015) has serious flaws to the extent that all the experimental results should be re-examined.

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.
