Flashcards in this deck (17)

• What is meant by AI?

  Simulation of intelligent behaviours by computers, collection of data and rules, ability to reason, ability to learn/adapt.
  ai definition
• How does an expert system diagnose a car's braking problem?

  User enters data, inference engine asks questions, decides on diagnosis, compares data to knowledge base, outputs diagnosis, shows how diagnosis was reached.

• What is one main characteristic of an AI system?

  Ability to learn/adapt, collection of data and rules, ability to reason, simulates intelligent behaviour, analyses patterns.
  ai characteristics
• What are characteristics of AI used by a robot in puzzles?

  Collects data, stores rules, ability to reason, ability to learn, makes predictions, analyses patterns.
  ai robot characteristics
• How will the robot's program use AI?

  Uses machine learning algorithms, collects data about paths and obstacles, stores successful/unsuccessful actions, identifies patterns.
  ai robot program
• How does an expert system operate?

  Has an interface, knowledge base, rule base, inference engine; applies rules to provide output/diagnosis, decides next questions based on input.

• Why is XYZ an example of a robot?

  It has electrical components, is programmable, has a mechanical structure.
  robot example
• What are the components of an expert system?

  Knowledge Base, Rule Base, Inference Engine, Interface.
  expert_system components
• What is the role of the inference engine in an expert system?

  Makes decisions by applying rules to facts to provide a result/diagnosis.
  expert_system inference_engine
• What is the role of the rule base in an expert system?

  Stores rules for the inference engine, links facts in the knowledge base.

• What are machine learning capabilities in AI?

  Form of AI, adapts/changest based on experience, improves performance over time.

• What does it mean for a robot to be automated?

  The robot can perform actions without human intervention.
  robotics automation
• What are three characteristics of a robot?

  1. It has a mechanical structure/framework. 2. It has electrical components. 3. It is programmable.
  robotics characteristics
• How does a robot know it has reached a fence using sensors and a microprocessor?

  1. A proximity sensor is used. 2. The sensor continuously sends digitised data to the microprocessor. 3. The microprocessor compares the data to a stored value. 4. If within range, the robot continues planting. 5. If outside range, a signal is sent to turn/stop the robot. 6. This process repeats until turned off.
  robotics sensors microprocessors
• What are two advantages of using an automated robot for planting seeds?

  1. The robot is more accurate when planting seeds. 2. The robot does not need to take breaks and works 24/7.
  robotics advantages
• What are two disadvantages of using an automated robot for planting seeds?

  1. The robot may have been expensive to purchase. 2. The robot may need maintenance, which may be costly.
  robotics disadvantages
• How does machine learning improve the robot's capabilities?

  1. The robot can adapt itself by changing its own rules/data. 2. It will become more efficient as it has greater knowledge of its surroundings.
