Abstract

fetched live from OpenAlex

This dataset contains predictions of Virtual ChIP-seq for binding of 34 transcription factors in Roadmap Epigenomics dataset tissues with matched DNase-seq and RNA-seq data. Tarball contains subfolders for each of the 34 TFs where Virtual ChIP-seq median MCC in validation cell types was > 0.3. Each subfolder contains gzipped BED files. Each file is named as _ _ _ _Predictions.bed.gz. Columns correspond to Chromosome, Start, End, _ _ _ , Posterior probability You can use the posterior probabilities provided in Virchip_PosteriorCutoffs.tsv. These are posterior probability cutoffs which maximized MCC in H1-hESC cell type, or are set to 0.4 if there was no ChIP-seq data of that TF in H1-hESC (0.4 is the mode of all optimal posterior probability cutoffs in H1-hESC).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
