Abstract
This paper presents an Efficient approach for state estimation of post-combustion CO 2 capture plants (PCCPs). The approach involves extracting lower-dimensional feature vectors from the high-dimensional operational data of PCCPs and constructing a reduced-order process model through proper orthogonal decomposition (POD). Multi-layer perceptron (MLP) neural network is then constructed and trained to approximate the dynamics of reduced-order process. For state estimation, a reduced-order extended Kalman filtering scheme, grounded in the POD-MLP model, is developed. Our simulations demonstrate that the proposed POD-MLP modeling reduces computational complexity in comparison to the POD-only model when applied to nonlinear systems. Additionally, the proposed algorithm can accurately reconstruct complete state information of PCCPs while markedly improving computational efficiency.

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
