Machine-Learning Digital Twin of Overlay Metal Deposition for Distortion Control of Panel Structures
Bibliographic record
Abstract
Cyber-manufacturing relies on smart digital-twins of manufacturing processes that can quickly act for making a wise decision. However, the cognitive computing part of the digital-twin becomes time-intensive beyond the requirement of a smart system when it uses simulation tools that solve governing constitutive equations in the form of partial differential equations (PDE). On the other hand, many artificial intelligence (AI) and machine learning (ML) solutions rely on a large data set that does not exist in many manufacturing systems. We build a hybrid digital-twin that takes advantage of an ML-based digital-twin for quick response while gaining fidelity through adaptive learning with a PDE-based digital-twin. We use our hybrid digital-twin for active exploration of various overlay metal deposition patterns in real-time. This tool enables engineers to explore and compare many patterns they need to assess metal deposition scenarios with no delay for computational time.

How this classification was reachedexpand
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.
