Abstract
Model Transformation is considered an important enabling factor for Model Driven Development. Transformations can be applied not only for the generation of new models from existing ones, but also for the consistent co-evolution of software artifacts that pertain to various phases of software lifecycle such as requirement models, design documents and source code. Furthermore, it is often common in practical scenarios to apply such transformations repeatedly and frequently; an activity that can take a significant amount of time and resources, especially when the affected models are complex and highly interdependent. In this paper, we discuss a novel approach for deriving incremental model transformations by the partial evaluation of original model transformation programs. Partial evaluation involves pre-computing parts of the transformation program based on known model dependencies and the type of the applied model change. Such pre-evaluation allows for significant reduction of transformation time in large and complex model repositories. To evaluate the approach, we have implemented QvtMix, a prototype partial evaluator for the Query, View and Transformation Operational Mappings (QVT-OM) language. The experiments indicate that the proposed technique can be used for significantly improving the performance of repetitive applications of model transformations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
