Abstract

fetched live from OpenAlex

Density functional theory simulations of graphite structures with random (in size and location) structural defects. Dataset contains coordinates of carbon atoms and the total energy computed using the PBE functional as implemented in the software VASP. Input parameter files are also included so that the calculations can be reproduced. NOTE: This dataset is useful for training machine learning models of carbon materials, as there are more than 500,000 unique calculations of graphene (3.5 nm x 3.5 nm unit cell). The dataset was used as training data for an extensive deep neural network which was used to simulate a micron of graphene.

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.
