Survey of AI

Two broad camps (though hard to define boundaries, much overlap, and many hybrid systems).
  1. Symbolic AI

  2. Sub-Symbolic AI

Explanation of the two camps

Cross-AI topics

These are entire problem fields by themselves.
May use elements of both camps of AI.
Each of these fields is an entire career by itself.

  1. Robotics
    • Walking/running over rough ground is hard (which adult humans, children and animals can all do).
    • Autonomous cars

  2. Computer vision

  3. Natural Language Processing (NLP) (and here)

The Word Lens app - OCR plus translation plus automated "photoshop".
Google bought Word Lens and this functionality is now incorporated into the Google Translate app. See videos.

Microsoft real-time speech translator (to be integrated into Skype).

Wikipedia: Sometimes I link to Wikipedia. I have written something In defence of Wikipedia. It is often a useful starting point but you cannot trust it. Linking to it is like linking to a Google search. A starting point, not a destination. I automatically highlight in red all links to Wikipedia and Google search and other possibly-unreliable user-generated content.
