Abstract
Abstract With the increase in the number of identified rare diseases and the intricacy involved in diagnosis, as exemplified by metabolic brain diseases, the need for computerized diagnostic systems is inevitable. We propose a pilot computer‐assisted medical decision support system (m CAD ) which tries to identify and further categorize these diseases, utilizing the information available from magnetic resonance spectroscopy ( MRS ) and diffusion‐weighted imaging ( DWI ). In this study, we have utilized wavelets, fuzzy relational classifiers and a collection of signal/image processing routines to extract and to classify disease features. The combined MRS + DWI system achieved a sensitivity ( S e) and positive predictivity ( PP ) of 65.00% and 72.22%, respectively, in detecting seven categories of metabolic brain diseases. The combined MRS + DWI system exhibits a 10% and 3.47% increase in S e and PP , respectively, in comparison to the system using only DWI information. It also increases the S e and PP of the system using only the MRS information by 15% and 22.22%, respectively .

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
