Artificial Intelligence in Healthcare Diagnostics, Personalized Education, and Smart Cities

Artificial Intelligence (AI) has emerged as a transformative technology across multiple domains, significantly improving decision‑making, efficiency, and service delivery. This research paper explores the role of AI in three critical application areas: healthcare diagnostics, personalized education, and smart cities. In healthcare, AI enhances disease detection, medical imaging analysis, and clinical decision support. In education, AI enables adaptive learning, intelligent tutoring systems, and personalized assessment. In smart cities, AI supports traffic management, energy optimization, public safety, and sustainable urban development. The paper discusses architectures, methodologies, benefits, challenges, and ethical considerations, supported by conceptual diagrams. The study highlights how integrated AI systems can contribute to improved quality of life and sustainable development.
