Real-world Impact: Pneumonia X-Ray Diagnosis with Privacy
The study demonstrates the effectiveness of Gaussian RanN-DP-SGD on the publicly available Pneumonia chest X-ray medical imaging dataset. This highly sensitive domain requires robust privacy while maintaining diagnostic accuracy. The proposed method achieves the most favorable privacy-utility trade-off, making it suitable for practical applications in healthcare where patient data privacy is paramount. It delivers acceptable performance within a privacy budget range of ε = 1 – 2, which is crucial for real-world medical diagnosis without compromising sensitive patient information.
