生物医学领域正探索将量子机器学习(QML)用于传统上由经典机器学习处理的任务,特别是在预测药物ADME(吸收、分布、代谢和排泄)性质方面,这些性质对药物评估至关重要。然而,ADME任务对现有量子计算系统(QCS)框架提出了独特挑战,因其同时涉及不平衡数据的分类与回归问题。这两种需求使得必须适应并改进现有的QCS框架以有效应对ADME预测的复杂性。本文提出一种新型的无训练评分机制,用于评估QML电路在不平衡分类和回归任务中的表现。该机制在不平衡分类任务中表现出显著的评分指标与测试性能的相关性。此外,我们开发了量化量子态间连续相似关系的方法,从而实现对回归任务性能的预测。这代表了一种针对回归应用的全新无训练量子电路搜索与评估方法。在代表性ADME任务上的验证——包括八个不平衡分类任务和四个回归任务——表明,我们的评分指标与电路性能之间存在中等程度的相关性,显著优于基线评分方法,后者表现出可忽略的相关性。
原文摘要 · Abstract (English)
The biomedical field is beginning to explore the use of quantum machine learning (QML) for tasks traditionally handled by classical machine learning, especially in predicting ADME (absorption, distribution, metabolism, and excretion) properties, which are essential in drug evaluation. However, ADME tasks pose unique challenges for existing quantum computing systems (QCS) frameworks, as they involve both classification with unbalanced dataset and regression problems. These dual requirements make it necessary to adapt and refine current QCS frameworks to effectively address the complexities of ADME predictions. We propose a novel training-free scoring mechanism to evaluate QML circuit performance on imbalanced classification and regression tasks. Our mechanism demonstrates significant correlation between scoring metrics and test performance on imbalanced classification tasks. Additionally, we develop methods to quantify continuous similarity relationships between quantum states, enabling performance prediction for regression tasks. This represents a novel training-free approach to searching and evaluating QCS circuits specifically for regression applications. Validation on representative ADME tasks-eight imbalanced classification and four regression-demonstrates moderate correlation between our scoring metrics and circuit performance, significantly outperforming baseline scoring methods that show negligible correlation.
