Artificial Intelligence (AI) is revolutionizing various industries, with healthcare being one of the most significantly impacted sectors. This paper provides an in-depth exploration of AI’s role in four critical areas. First, the authors investigate the integration of AI with edge computing, highlighting how data fusion methods are employed to process information closer to its source, addressing issues like bandwidth limitations and latency. The paper further examines multimodal analytics, where diverse data sources are combined to improve decision-making and accuracy. Another key area discussed is human-centred AI, which blends expert knowledge with AI models to create transparent, reliable systems, especially in fields such as agriculture and forestry. Lastly, the paper covers the Internet of Medical Things and its influence on healthcare, utilizing IoT devices, wearables, and telemedicine to enhance patient care and diagnostic accuracy. Beyond healthcare, AI is making an impact in other sectors like finance, cybersecurity, and autonomous systems. In healthcare, data fusion is critical for combining medical imaging and real-time data, enhancing diagnostic precision. The integration of AI in wearable technologies is also improving health monitoring. Despite the promising advancements, challenges such as data privacy, transparency, and biases in AI models remain significant. The authors argue for the development of ethical frameworks and robust, explainable AI (XAI) to ensure these technologies are trustworthy and beneficial for all.
