Abstract

fetched live from OpenAlex

The identification of a turbomachine model is carried out within the linear parameter-varying framework with the aim of improving model precision and reliability, especially in large transients, thereby improving control performance in future work. An appropriate model structure and a new parameter dependency are selected and the recursive least squares algorithm is employed for determining the parameters to be estimated. A model is obtained for high transients. Validation results are carried out with a simulated high fidelity nonlinear model. The new model is compared to an existing gain-scheduling model, showing better precision and validating the approach. The proposed approach is detailed in this work and concluded with objectives and future perspectives.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
