Machine Learning in Healthcare: From Diagnostics to Personalized Medicine and Predictive Analytics

摘要

Background: Machine learning (ML) has profoundly revolutionized the healthcare sector by enhancing diagnostic precision, forecasting patient outcomes, individualizing treatment strategies, and streamlining healthcare processes. Notwithstanding its progress, issues of data privacy, security, algorithmic bias, and model openness impede extensive implementation. Methods: This review consolidates current research on machine learning applications in healthcare, emphasizing supervised, unsupervised, and reinforcement learning methodologies. It examines their functions in illness diagnosis, risk evaluation, medical image analysis, and tailored therapy approaches. This research also investigates new technologies, such federated learning and hybrid models, designed to tackle data-related difficulties while safeguarding patient privacy. Results: Supervised learning has greatly enhanced clinical decision-making, especially in illness identification and patient surveillance. Deep learning, particularly convolutional neural networks (CNNs), has transformed medical image processing, enhancing the early identification of illnesses like skin cancer and diabetic retinopathy. Reinforcement learning has shown potential in robotic surgery and individualized treatment planning. Nonetheless, obstacles such as disjointed healthcare data, ethical dilemmas, and legal limitations persist in affecting the deployment of machine learning. Conclusion: The future of machine learning in healthcare depends on advancing model interpretability, augmenting data-sharing frameworks, and incorporating ethical concerns to guarantee equitable and dependable healthcare provision. Progress in privacy-preserving methodologies and multidisciplinary partnerships will be essential in addressing current obstacles and promoting the ethical implementation of machine learning in clinical practice and policy formulation.
