Abstract
This article is concerned with detecting cellwise outliers in large data matrices. We introduce a novel method that is able to fully exploit dependence structures among variables while controlling the false discovery rate (FDR). We reframe cellwise outlier identification into a high‐dimensional variable selection paradigm and construct “binate references” for data screening, estimation and information pooling. With the binate references, the proposed procedure forms a series of statistics that incorporate covariance information and utilizes a global symmetry property of these statistics to approximate the false discovery proportion. We show that the proposed method can control the asymptotic FDR under some mild conditions. Extensive numerical studies demonstrate that our method has reasonable FDR control and satisfactory power in comparison to existing methods.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
