Abstract
In this study, a hybrid optimization XGBoost model was used to predict the slump of concrete. This optimization model combines grid search and particle swarm optimization (PSO) algorithm. The grid search is used to determine the maximum depth and the number of trees in XGBoost, while the particle swarm optimization optimizes other floating-point hyperparameter ranges to improve the predictive accuracy of the model. The factors influencing the slump of concrete include water, cement, fine aggregate, coarse aggregate, and water reducer, which are represented by seven parameters. The model performs excellently in both the training and testing sets, with a coefficient of determination (R2) exceeding 0.97. In conclusion, this study demonstrates that the hybrid optimization of the XGBoost model using grid search and particle swarm optimization algorithm can accurately predict the slump of concrete, which is of significant importance for controlling and optimizing the concrete production process.

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
