Question
. Give a PEAS description of each of the following task environments. a. A simple thermostat that turns on a heater when the temperature is at least 3 degrees below the setting, and turns off a heater when the temperature is at least 3 degrees above the setting. b. A route recommendation system which computes and suggests the “best” route to reach a destination. c. A group of ants searching for the shortest path from their nest to food sources. d. A computer program that given an image of a fingerprint can find the best match in a database of criminal fingerprints.
2. Characterize each task environment in problem 1 above in terms of the following properties: a. Single- or multi- agent. b. Deterministic or stochastic. c. Sequential or episodic. d. Static or dynamic. e. Discrete or continuous. f. Fully- or partially- observable.
2. Characterize each task in Problem 1 as an instance of a simple reflex agent, a modelbased agent, goal-based agent, utility-based or a learning agent?
Explanation / Answer
1. Thermostat:
Performance measure: The only performance measure for a thermostat is its ability to maintain the user-set temperature
Environment: A thermostat is expected to work efficiently in a room or house.
Actuators: Heater is the actuator. It should either switch on (when the temperature is at least 3 degrees below the setting), or switch off (when the temperature is at least 3 degrees above the setting).
Sensor: The sensor here is a temperature sensor.
2. Route recommendation system
Performance measure: The correctness of the recommended routes
Environment: City Roads
Actuators: Display monitor, that would show the routes graphically as a map or GPS navigation system, OR may list down the points and directions to be followed
Sensor: Data comprising of length of a particular road, its width, details of traffic at different times, etc.
3. Ants:
Performance measure: Number of steps taken to reach their destination, i.e. ants should not feel tired!
Environment: Sand or dusty ground
Actuators: Ants’ feet
Sensor: Their eyes, brain or any other sensory organ by which they could estimate the distances of different paths
4. Computer program:
Performance measure: Accuracy is the only performance measure
Environment: A database of image files
Actuators: Processor
Sensor: Algorithm that is used to compare different images, and the parameters it takes
