Abstract
Persistent exploration of high stiffness two-dimensional (2D) materials is necessary for advancements in applications such as nanocomposites, flexible electronics, and resonant sensors, all of which demand elevated resistance to deformation. However, data-centric material models developed for this purpose remain in their early stages, often due to incomplete stiffness estimation or limited transferability to unseen 2D materials. In this context, we examined stiffness trends among different classes of 2D materials and identified the elastic constants pivotal for estimating the 2D material stiffness irrespective of their crystal symmetry. Subsequently, we developed Gaussian Process Regression machine learning models with the capability of relative stiffness comparison, which are used to predict high stiffness candidates across a broad spectrum of unseen 2D materials during model training. The probability of finding high stiffness 2D materials increased significantly, from a mere 1% in the training data set to a notable 47% in the set of machine learning-predicted 2D materials. We also discussed potential stiffening mechanisms, competing stiffness characteristics, and complementary properties of these predicted high-stiffness 2D materials that are crucial for enhancing the effectiveness of the aforementioned applications.

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
