Towards the Visualization and Understanding of Diagnoses in a Physical System 1
Bibliographic record
Abstract
Diagnosis of physical systems such as car or aircraft engines tends to be a complex activity. Technicians combine textual manuals with schematics and some analysis of measured data to diagnose and repair engines. Knowledge-based system designers have added heuristics to hypermedia (mostly text and graphic) representations of manuals to simplify the tasks of the technicians as in JETA [Halasz91]. Knowledge browsers for such systems are used by the knowledgeengineers to structure and input the knowledge base and in a limited capacity are used to help the domain experts visualize the knowledge and the various possible relations as implemented for the JETA browser. In RATIONALE, a diagnostic system that reasons by explaining, explanation was used to understand the reasoning in the knowledge-based system [Abu-Hakima90]. This position paper argues that although these knowledge-based approaches help in the visualization and understanding of diagnoses in physical systems, they need to be improved and better integrated into an overall diagnostic system. Some of the many issues that arise in trying to achieve this are discussed in the paper.

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.
