AI and Expert Systems Case Study Case Study: MYCIN Expert System for Bacterial Infections Background: MYCIN was an early expert system developed at Stanford University in the 1970s, designed to diagnose bacterial infections and recommend antibiotic treatments. Key Features:  Knowledge base with about 600 rules from medical experts  Inference engine using backward chaining  Uncertainty handling with certainty factors  Natural language interface for doctor interaction Performance: MYCIN outperformed junior doctors and matched or exceeded experienced specialists in diagnosing bacteraemia and meningitis. Significance:  Demonstrated AI's potential in medical diagnosis  Pioneered uncertainty management in expert systems  Influenced subsequent medical AI development Limitations:  Not used clinically due to ethical and legal concerns  Limited by contemporary computing technology  Struggled with explaining reasoning satisfactorily Legacy: While not clinically deployed, MYCIN influenced many subsequent expert systems and modern clinical decision support systems. 2.1 Define Artificial Intelligence and explain the difference between narrow AI and general AI within the context of MYCIN. Provide two examples of each and also describe five key aspects of human intelligence. For each aspect, explain how it relates to both human cognition and current AI capabilities. [10 marks]

claims? Q.9 (a)Consider the number of annual claims model by Poisson distribution with parameter $\mu$ and prior distribution of $\mu$ is gamma with parameters $(\alpha,\beta)$. Find Bayes estimator of $\mu$. If prior distribution of $\mu$ has parameters $(\alpha=4,\beta=6)$ and four annual claims are 3,4,6,8, calculate the Bayes estimator of $\mu$ and Bayesian credibility.

Suppose that a car-rental agency offers insurance for a week that costs $75. A minor accident will cost $2,000, whereas a major accident might cost $16,000 in repairs. Without the insurance, you would be personally liable for any damages. You researched insurance industry statistics and found out that the probability of a major accident is 0.05% and that the probability of a fender bender is 0.16%. What is the expected value for each decision? What should you do?
