Quantum-classical Hybrid Machine Learning (QHML) models are known for their robust performance in anti-cancer drug response prediction, especially with limited datasets.
Hybrid models are sensitive to data encoding, with suboptimal choices causing stability issues.
To improve, a novel normalization strategy using a moderated gradient version of $ anh$ was proposed to enhance model stability by transforming neural network outputs without concentrating them at extreme value ranges.
Evaluation on gene expression and drug response data showed QHML outperforming classical models when data was optimally normalized, signaling potential for quantum computing in biomedical data analysis.
