Why do I need AI?

• Engineering: To get machines to do a wider variety of useful things
  • e.g., understand spoken natural language, recognize individual people in visual scenes, find the best travel plan for your vacation, etc.
• Cognitive Science: As a way to understand how natural minds and mental phenomena work
  • e.g., visual perception, memory, learning, language, etc.
• Philosophy: As a way to explore some basic and interesting (and important) philosophical questions

e.g., the mind body problem, what is consciousness, etc.

Why does AI can't invent things?

what can AI do?

Here are some example applications

• Computer vision: face recognition from a large set
• Robotics: autonomous (mostly) automobile
• Natural language processing: simple machine translation
• Expert systems: medical diagnosis in a narrow domain
• Spoken language systems: ~1000 word continuous speech
• Planning and scheduling: Hubble Telescope experiments
• Learning: text categorization into ~1000 topics
• User modeling: Bayesian reasoning in Windows help (the infamous paper clip…)
• Games: Grand Master level in chess (world champion), perfect play in checkers, professional-level Go players
