Abstract
Abstract A set of feed forward multilayer neural network models have been proposed to predict CH 4 conversion, C 2 and ethylene selectivity of methane oxidative coupling under periodic operation. These parameters predicted by the proposed neural network are based on cycle period, cycle split, and CH 4 and O 2 mole fractions in the first and second part of the period. Due to the dynamic nature of periodic operation and the kinetic complexity of the investigated reactions, the proposed approach is an effective tool to model the system. The agreement between model predictions and experimental data was quite satisfactory. The models could be employed to optimize the experimental conditions in order to get better output from the catalytic reaction. It is concluded that the neural network is an effective tool for modeling catalytic chemical reactions under periodic operation.

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
