Q/1 a. An automatic irrigation system predicts the amount of water (small or large) and frequency of watering (low or high) to plants in daily basis based on the detected moisture content (dry or wet) and environmental parameters (hot or cold). Explain how the process can be formulated as a Hidden Markov Model. What assumptions are required? b. The reliability of a system can be enhanced by redundancy, which means building two or more independent devices to do the same job, such as three independent braking systems in an automobile. Do you agree with this statement? Justify your answer by considering the following situation. Suppose each device has a very high accuracy percentage, ranging from 90% to100% of detecting contraband in airline luggage. If the luggage is checked three times by three different devices independently of one another, what is the probability that contraband will be detected? In the calculation, you need to assign the percentage of accuracy to each device. Q/1 a.
