- Not quite. The program is given a *goal*. The goal usually being
- positive outside reinforcement. (Or positive *internal* reinforcement, with
- satisfaction of that reinforcement acheiveable only through outside stimuli)
- The program works towards that goal by
- modifying *itself*. One DOES NOT program it with ANY specific data/behaviour
- in mind. In fact even the goal acheivement programming is left quite vague.
- Working with a neural network, self-modification becomes trivial, since the
- behaviours of each cell change as their data changes, automaticaly. And while
- each cell may have a specific goal, and change its behaviour according to
- that specific goal in relation to itself, the overall mass of cells may
- behave quite dramaticaly different.
-
- There is a *HUGE* difference in simply "learning" and "learning to
- learn". The true AI program is able to "learn to learn" by its own self
- modification. In other words, it becomes more intelligent by itself as it
- learns learning techniques and creates within itself the ability to *think*.

- YES! EXACTLY! IT CHANGES ITSELF! THIS IS AN ABSOLUTE NECESSITY!
-
- There is also another *huge* difference when outputs are wrapped
- around and fed back in as inputs. This allows the program to see the
- consequences of its actions and modify itself accordingly in order to
- acheive its goal.

- Like I said... You are confusing "Expert Systems" with true AI.
- In an Expert system, one is attempting to create an "adult", complete with
- all the knowledge insights and abilities of an "adult". In AI, the objective
- is to create an "infant" that will grow...
