Abstract

fetched live from OpenAlex

Profiles are regularly encountered in chemical process modeling, and often arise in situations in which products are characterized by a distribution, such as in molecular weight distributions or particle size distributions in polymer production. Approaches for modeling such problems include using a specified distribution characterized by a small number of parameters, or discretization and application of multivariate statistical methods such as Partial Least Squares (PLS). In this paper, an alternative approach using functional regression is presented in which the distribution is expressed using a suitable set of basis functions such as splines, and the parameter estimation problem includes both the coefficients in this basis, as well as the model parameters. The efficacy of the functional regression and PLS approaches is compared using a polystyrene reactor example.

Full frame distilled prediction

Teacher imitation

Not 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.
