Abstract
Abstract The integrated deconvolution estimation model (IDEM) to estimate the microstructural parameters of polyolefins made with multiple‐site catalysts is described. IDEM estimates ethylene/ α ‐olefin reactivity ratios for each site type in two‐steps. In the first step, the MWD of the whole copolymer is deconvoluted into several Flory's most probable distributions, to determine the number of site types and the weight fraction of copolymer made on each of them. In the second estimation step, the model deconvolutes the CSLD of the copolymer into its individual components per site type, and estimates their respective reactivity ratios. This is the first time that MWD and CSLD information is integrated to estimate the reactivity ratios of polyolefins made with multiple‐site catalysts. magnified image

Full frame distilled prediction
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
