Private and interpretable clinical prediction with quantum-inspired tensor train models
An arXiv preprint argues that publicly released clinical machine learning models can leak training patient information through their parameters or outputs, and that logistic regression, widely used in clinical settings, worsens this risk. The paper proposes quantum-inspired tensor train models as a private and interpretable alternative for clinical prediction.

If tensor train models demonstrate reduced training-data memorization under privacy audits, they could become a safer default for sharing clinical prediction models within the next two years.
Tensor train parametrizations compress model weights and may limit the capacity to encode individual patient records, while their factorized form could preserve interpretability. This would only happen if follow-up empirical studies confirm the privacy benefit without sacrificing predictive performance, and if clinical model repositories adopt such models as an alternative to logistic regression.
