An internet-based fuzzy logic expert system for organ transplantation assignment
Bibliographic record
Abstract
Organ transplantation is lifesaving. However, the demand for organs far exceeds supply. Due to the resource scarcity (i.e. organs), the special medical requirements for organ transplanting and the urgency in getting the organ to the recipient, it is critical to use information technology to coordinate the organ procurement and transplanting process and to allocate donated organs to recipients quickly, fairly and effectively. In this paper we analyse how information technology can be used to improve organ transplantation services and propose the use of an internet-based fuzzy logic expert system to assist physicians in solving the multi-criteria kidney allocation problem. A pilot fuzzy logic expert system for kidney allocation was developed and evaluated in comparison with two existing allocation algorithms a priority sorting system used by the Multiple Organ Retrieval and Exchange (MORE) program in Ontario, Canada and a point scoring systems used by the United Network for Organ Sharing (UNOS) in the USA. Our simulated experiment based on real patient data confirms that the fuzzy logic system can represent the expert's thinking in a satisfactory manner in handling complex trade-offs and overall, the fuzzy logic derived recommendations were more acceptable to the expert than those from the MORE and UNOS algorithms.

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.
