Examples include INTERNIST-1 and its successor, CADUCEUS, which were used for diagnosing complex medical conditions [3]. The late 1980s and 1990s marked the advent of machine learning techniques. Neural networks and early forms of pattern recognition started to be applied to medical imaging and diagnostics [1].

2000s: Advancements in data and algorithms: The widespread adoption of Electronic Health Records (EHRs) provided a wealth of data that AI systems could leverage. Machine learning algorithms began to be used for predictive analytics, identifying patient risk factors, and improving clinical decision support. The Human Genome Project, completed in 2003, generated large datasets that spurred the development of AI algorithms for genomics and personalized medicine [4].

2010s-Present: Deep learning and big data: The emergence of deep learning revolutionized AI in healthcare. Convolutional Neural Networks (CNNs) and other deep learning models achieved remarkable success in image recognition, making them highly effective for analyzing medical images like X-rays, MRIs and CT scans [5]. Advances in Natural Language Processing (NLP) enabled AI systems to process and analyze vast amounts of unstructured clinical data, such as physician notes and research articles, facilitating better information retrieval, clinical documentation and decision support. AI techniques, including machine learning and deep learning, have been increasingly used in drug discovery and development, significantly accelerating the process of identifying potential drug candidates [4].
