Strong Grain Neighbour Effects In Polycrystals- Data Set
Bibliographic record
Abstract
3D-XRD measurements are for a commercially pure zirconium (CPZr) sample deformed in-situ to 1.2% strain. HR-EBSD measurements are for the same deformed sample after unload. Crystal Plasticity Finite Element (CPFE) simulation was done on the measured micro-structure and results of the NHS model are provided. HR-EBSD and CPFE results are generated using in-house codes. Details of the 3D-XRD codes are provided in the following link: https://sourceforge.net/p/fable/wiki/Home/ The work and further analysis of the results are described in: "Strong Grain Neighbour Effects in Polycrystal" Published in Nature Communications, DOI: 10.1038/s41467-017-02213-9 Other relevant papers: Abdolvand, H., Majkut, M., Oddershede, J., Wright, J., Daymond, M.

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.
