幻覚と制約:精度を超えた手術ワークフロー認識の規制
Hallucinations and Constraints : Regulating surgical workflow recognition beyond accuracy
医療画像処理におけるAIの幻覚問題を、トポロジー誤差として定義し、線形時相論理と確率的グラフィカルモデルで制約を課すことで、手術フェーズ認識の精度を約10%向上させつつ誤差を大幅に削減する手法を提案した。

Hallucinations are a major concern for the integration of artificial intelligence into medicine, although less explored in the realm of medical image processing. Unlike problems in natural text understanding and reasoning therewith, determining whether or not predictions derived from biomedical images and signals is less intuitively clear. This article suggests that topological errors could constitute hallucinations in a way that can be more readily measured and thus regulated. Certain of these properties for certain types of problems, such as biomedical signal segmentation, can be rephrased as linear temporal logic predicates, a number of which can be explicitly enforced using probabilistic graphical models. Our simulations show the potential of these explicitly constrained predicates for the case of automatic surgical phase recognition in robot-assisted hysterectomy, improving accuracy by approximately 10% while removing the vast majority of topological errors, suggesting that mathematical guarantees of correctness can supplement other empirical forms of regulating machine learning in medical image computing and computer-assisted interventions.
