"On Intelligence" Book Review

Yeah, I know, I blogged about this many, many months ago. Well, I’ll keep this short and sweet:


  • The book made so many things ‘click’
  • Short Chapters ( except Chapter 6 )
  • Approachable subject matter ( except Chapter 6 ), even people with little experience with AI, biology, or neuroscience.


  • Chapter 6 could have been broken down into seperate chapters & is a BIT technical to absorb all at once.

And that’s pretty much it. It’s a GREAT book and, in time, could become a seminal book in the field of computation and AI.

My favorite part of the book was how Jeff breaks down how the neocortex works by:

  • Establishing patterns
  • Creating ‘Invarient Representations’ of things
  • Maintaining a hierarchy of sorts
  • Connecting two concepts in an auto-associative manner

Of these features, the ‘Invarient Representation’ theory is the most interesting. Think about how you can recognize a song, even when it’s played without words, without music, or even in a different pitch or speed than what you originally heard. Our brain can process things we see and hear, and create sort of abstract representations of the input.

Anyway, before I go on and on, stop now and pick up the book. You’ll be glad you did.
