- 요약Public health challenges require sophisticated analytical approaches to handle massive, heterogeneous datasets spanning genetic, behavioral, social, and clinical domains across diverse populations and geographic regions. While classical statistical methods struggle with such complex data structures, deep learning models demonstrate significant potential in delivering more accurate predictive solutions with big data. This study addresses key concepts in computational statistics including prediction performance improvements, ground truth quality, big data approaches, and model interpretability through two distinct applications in public health diagnostics. We present SPARK, a deep learning model for RT-qPCR curve analysis that significantly outperforms current practice in SARS-CoV-2 testing. SPARK achieves a false negative rate of 1% with only 4.38% false positives, compared to over 60% false positives with conventional thresholding methods. Critically, we train SPARK using true ground truth labels from RT-qPCR quality control curves rather than human-generated labels, enabling the model to learn beyond current thresholding practice and differentiate itself from other deep learning approaches trained on human labels. In pathological image analysis, we demonstrate deep learning applications in two clinical contexts: predicting breast cancer development from benign breast disease whole slide images and detecting pancreatic malignancy from fine-needle aspiration cytology images. One of our models significantly outperforms estimated clinician prediction for breast cancer risk (AUROC: 0.577 vs. 0.472, p ≤ 0.05) and the other model achieves high accuracy in pancreatic malignancy detection with an average precision of 0.98. Our methods enable accurate diagnostic guidance through attention-based interpretability methods that highlight relevant image regions for clinical decision-making. These applications demonstrate how computational methods can transform public health practice by leveraging high-quality ground truth data and deep learning architectures to improve diagnostic accuracy and enhance clinical decision support.
