Supplementary Textbook
- Book title: Artificial Intelligence, A modern approach
- Authors: Stuart Russell, Peter Norvig
- Publisher: Pearson
- Edition: Fourth edition (2021)
Today's Class: Introduction to Artificial Intelligence
- Course Overview
- What is AI?
- A branch of science helping machines solve complex problems human-like
- Borrowing human intelligence characteristics
- History of AI
- Foundations of AI
- Application of AI
- Intelligent Agents
Big Questions about AI
- Can machines think?
- If so, how?
- If not, why not?
- What does this say about human beings?
Why Study Artificial Intelligence?
- AI makes computers more useful
- Intelligent computers have a huge impact on civilization
- AI is a sought-after field by scientists of all disciplines
- Computers are a useful tool to discuss and understand intelligence.
What is Artificial Intelligence?
- AI is a branch of science dealing with helping machines find solutions to complex problems in a more human-like fashion.
- It involves using human intelligence characteristics in algorithms for computers.
- Some view intelligence as internal thought processes, while others focus on outward behavior.
History of AI
- Inception of AI (1943-1956)
- Early enthusiasm, great expectations (1952-1969)
- A dose of reality (1966-1973)
- Expert systems (1969-1986)
- Return of neural networks (1986-present)
- Probabilistic reasoning and machine learning (1987-present)
- Big data (2001-present)
- Deep learning (2011-present)
What Can AI Do?
- Play Jeopardy
- Beat humans at chess
- Beat humans at Go
- Play table tennis
- Grab a cup
- Unload a dishwasher (unsupervised)
- Drive safely along highway (unsupervised) - Note: Some tasks not possible currently.
- Buy groceries online
- Buy groceries in-store
- Discover mathematical theorems
- Perform surgery
- Unsupervised dishwasher unloading with collaboration
- Translate spoken Chinese to English
- Write funny stories
Unintentionally Funny Stories
- Includes three short stories with humorous situations, lacking specific details about AI.
What About the Brain?
- Human brains are good at rational decision-making, but not perfect.
- Human brains aren't as modular as software, making reverse engineering difficult.
- Memory and simulation are key to decision-making in brains.
Course Syllabus
- Part I: Making Decisions
- Fast search/planning
- Adversarial and uncertain search
- Part II: Reasoning under Uncertainty
- Bayes' nets
- Decision theory
- Machine Learning
- Throughout Applications
- Natural language, vision, robotics, games
AI Perspectives
- Four main perspectives:
- Thinking humanly (cognitive modeling)
- Acting humanly (Turing test)
- Thinking rationally ("laws of thought")
- Acting rationally (rational agent)
AI Perspectives: Acting Humanly
- Turing test—designed as a thought experiment to avoid the philosophical vagueness of "machine thought."
- Natural language processing, knowledge representation, automated reasoning, and machine learning are needed to successfully think and communicate like humans.
AI Perspectives: Thinking Humanly
- Introspection
- Psychological experiments
- Brain imaging
AI Perspectives: Thinking Rationally
- Aristotle's attempt to codify "right thinking" and logical traditions
- Logicist tradition in AI—developing programs that solve problems from a logical notation
- The theory of probability to allow reasoning with uncertain information.
AI Perspectives: Acting Rationally
- Agents are entities that act
- Rational agents act to achieve best outcomes (expected when uncertain).
- Standard model of AI—agents that perform appropriate actions for the given objectives.
What is the Definition of Artificial Intelligence?
- Thinking humanly: observing human thought processes
- Thinking rationally: following rules of thought
- Acting humanly: performing tasks like a human
- Acting rationally: acting in a way to optimize expected outcomes
The Foundation of AI
- Roots in numerous disciplines; including philosophy, mathematics, economics, neuroscience, cognitive science, computer science/engineering and control theory/cybernetics.
Foundations of AI: Specific Disciplines
- Philosophy: formal rules, mind's origins, knowledge
- Mathematics: formal logic, computation, uncertainty reasoning
- Economics: decision-making, preferences, future outcomes
- Neuroscience: brain information processing
- Psychology: human/animal thought/action
- Computer Science/Engineering: building efficient computers
- Control Theory/Cybernetics: control of systems.
The State of the Art
- Examples of current AI capabilities.
Risks and Benefits of AI
- Various concerns related to the development and use of AI systems.
Next Class: Intelligent Agents
- Introduction, structure, properties of intelligent agents
- Agent configurations, types of agents (simple, model-based, goal-based)
- Learning agents, and types of environments
