Quantum Cognition Machine Learning for Forecasting Chromosomal Instability

  • 基于量子力学原理构建状态向量,实现上下文感知的特征建模。
  • 在小样本高维数据上优于传统方法,准确识别染色体大尺度状态转变。
  • 适合处理单细胞病理数据,助力癌症早期转移风险评估。

从循环肿瘤细胞(CTCs)形态准确预测染色体不稳定性,可在液体活检中实现实时检测高转移潜能的CTCs。然而,由于单细胞数字病理数据维度高、结构复杂,该任务极具挑战。本文引入量子认知机器学习(QCML),一种受量子力学启发的计算框架,用于从转移性乳腺癌患者CTCs的形态特征中估计染色体不稳定性。QCML将数据表示为希尔伯特空间中的状态向量,实现上下文感知的特征建模、降维与泛化增强,无需人工特征选择。在外部验证的CTCs数据集上,QCML在识别预测的大规模状态转变(pLST)状态方面显著优于传统机器学习方法。初步结果表明,QCML是一种在高维、小样本生物医学场景下表现优异的新工具,可模拟类认知学习,实现从CTC形态中发现生物学意义的染色体不稳定性预测,为液体活检中的CTC分类提供新范式。

原文摘要 · Abstract (English)

The accurate prediction of chromosomal instability from the morphology of circulating tumor cells (CTCs) enables real-time detection of CTCs with high metastatic potential in the context of liquid biopsy diagnostics. However, it presents a significant challenge due to the high dimensionality and complexity of single-cell digital pathology data. Here, we introduce the application of Quantum Cognition Machine Learning (QCML), a quantum-inspired computational framework, to estimate morphology-predicted chromosomal instability in CTCs from patients with metastatic breast cancer. QCML leverages quantum mechanical principles to represent data as state vectors in a Hilbert space, enabling context-aware feature modeling, dimensionality reduction, and enhanced generalization without requiring curated feature selection. QCML outperforms conventional machine learning methods when tested on out of sample verification CTCs, achieving higher accuracy in identifying predicted large-scale state transitions (pLST) status from CTC-derived morphology features. These preliminary findings support the application of QCML as a novel machine learning tool with superior performance in high-dimensional, low-sample-size biomedical contexts. QCML enables the simulation of cognition-like learning for the identification of biologically meaningful prediction of chromosomal instability from CTC morphology, offering a novel tool for CTC classification in liquid biopsy.
