Predictive models for dynamic modulus using weighted least square nonlinear multiple regression model
Bibliographic record
Abstract
The objectives of this paper are (1) to evaluate the dynamic modulus prediction models and (2) to develop an alternative prediction model using the nonlinear multiple regression method. A total of 14 field produced mixture types (in a total of 1314 measurements) with various designed traffic levels and aggregate sizes were used. Two prediction models, the Witczak prediction model developed in 2006 and the Hirsch model developed in 2003, were revised in this study. In addition, the revised Witczak prediction equation was simplified using fewer independent variables (11 variables instead of 21 variables); and values of the newly revised coefficients with improved accuracy for Hirsch model are presented in this paper. A new model using the weighted least square nonlinear multiple regression model (WLS NLR) was developed in this study. It was found that the WLS NLR has a better prediction when compared with other prediction models used in this study.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
