Human intelligence involves observing and learning through the real-world to build a mental model to finally take a decision. With the explosion of data, and increase in computational power, various tools and techniques can be used to speed up this decision-making process using mathematical and predictive models. This is how artificial intelligence (AI) functions in relatively less time and much lower cost. Increasing complexity and volume of data, along with rising cost, makes healthcare a perfect case for the application of AI. You can view below the application of AI in the healthcare system; starting from drug discovery, to prevention and monitoring, treatment, and reimbursement.
