This hybrid framework uses Quantum Circuit Born Machines to generate synthetic samples that effectively mitigate class imbalance in tabular datasets without requiring full-scale fault-tolerant quantum hardware. By leveraging parameterized circuits to model complex probability distributions, the approach yields measurable gains in F1-scores and minority-class recall on standard benchmarks like Iris and Telco Customer Churn. The results suggest a viable near-term pathway for integrating specific quantum advantages into classical machine learning workflows addressing data scarcity issues.
Quantum Circuits Cut Data Imbalance Recall Gap by 10–25%
Hybrid quantum-classical models using Quantum Circuit Born Machines address data imbalance, improving recall by 10–25% on tabular datasets.
A new hybrid quantum-classical framework is demonstrating a measurable improvement in machine learning performance on imbalanced datasets, with researchers reporting a 5, 15% increase in F1-score and minority-class recall improving by 10-25%. The team, comprised of Tanapol Nuatho, Narisorn Sangnakara, Prapong Prechaprapranwong, and Rajchawit Sarochawikasit, developed a Quantum Circuit Born Machine (QCBM) to generate synthetic data that addresses limitations caused by data scarcity and class imbalance. Experiments utilizing the Iris dataset and the Telco Customer Churn dataset show that augmenting training data with QCBM-generated samples at 40-50% of the minority class improves F1-score by approximately 5-15%. Cross-domain evaluations revealed a performance gap of only 3-10%, indicating a high degree of distributional fidelity for the quantum-generated samples. A five to fifteen percent increase in F1-score and minority-class recall improving…
