    Study Notes

    Introduction to AI

    • Artificial Intelligence (AI) focuses on designing intelligent systems.
    • The term "AI" was coined by John McCarthy in 1956.
    • Intelligence involves acquiring, understanding, and applying knowledge to achieve goals.
    • AI examines intellectual processes as computational operations.
    • AI aims to create machines capable of thinking and acting like humans, including learning and problem-solving.

    Sub-Areas of AI

    • Game Playing: AI programs have achieved mastery in games like chess, with Deep Blue defeating world champion Gary Kasparov.
    • Speech Recognition: Systems like PEGASUS for American Airlines allow users to interact with reservation systems via voice.
    • Computer Vision: AI is used for face recognition, autonomous vehicle navigation (like CMU's ALVINN), and various other applications.
    • Expert Systems: These systems are designed to mimic human expertise in specific fields.
      • Diagnostic Systems: Examples include MYCIN for diagnosing blood infections and Intellipath for pathology diagnosis.
      • System Configuration: DEC's XCON for custom hardware configuration is an example.
      • Financial Decision Making: AI helps detect fraud and expedite transactions in finance.
      • Classification Systems: These systems categorize information based on multiple data sources.
    • Mathematical Theorem Proving: AI systems employ inference methods to prove new theorems.
    • Natural Language Understanding: AI facilitates translation of web pages (like AltaVista) and technical manuals.
    • Scheduling and Planning: AI is used in manufacturing scheduling, logistics planning, and spacecraft operations.
    • Artificial Neural Networks: These networks mimic the structure of the human brain for learning and problem-solving.
    • Machine Learning: This area focuses on enabling computers to learn from data without explicit programming.

    Applications of AI

    • AI algorithms are utilized in various fields:
      • Business & Finance
      • Engineering
      • Manufacturing
      • Medicine
      • Education
      • Fraud Detection
      • Object Identification
      • Information Retrieval
      • Space Shuttle Scheduling

    Building AI Systems

    • Perception: AI systems need sensory inputs (like images, sounds, or data) to understand the environment.
    • Reasoning: This involves decision-making, inference, and classification based on perceived data and internal models. Various techniques like neural networks, logical deduction, and heuristics are employed.
    • Action: AI systems interact with the world through actions, including controlling robots, generating language, or making diagnoses.

    Definitions of AI

    • Cognitive Science Approach:*

    • Think Human-Like: Focuses on simulating human thought processes using computational models.

    • Goal: To create machines that reason in a similar manner to humans.

    • Laws of Thought Approach:*

    • Think Rationally: Employs formal systems of logical rules and inferences to ensure optimal solutions.

    • Goal: To formalize reasoning processes.

    • Turing Test Approach:*

    • Act Human-Like: Focuses on creating machines that behave indistinguishable from humans in interactions.

    • Goal: To trick an interrogator into believing a machine is human.

    • Rational Agent Approach:*

    • Act Rationally: Emphasizes designing agents that make the most appropriate decisions according to a specific performance measure.

    Rationality

    • A rational agent performs actions that maximize its success based on:
      • Performance measure (criteria for evaluating success)
      • Prior knowledge of the environment
      • Actions it can perform
      • Percept sequence (observed data)

    Omniscience, Learning, and Autonomy

    • Omniscience: A hypothetical agent with perfect knowledge of all outcomes is impossible.
    • Learning: Rational agents adapt and learn from their experiences rather relying solely on pre-defined knowledge.
    • Autonomy: An agent is autonomous when it can make decisions based on its own observations.
