Neural Networks for and and or

• consider the statement: "X" happened and also "Y" happened
  • both activities X and Y must be accomplished for the statement to be considered "true"
  • the absence of either activity renders the statement false
• consider the statement: either "X" happened or "Y" happened
  • statement is considered "true" if only one event, but not both events, takes place

If True is noted with 1, and false with 0, then:

• AND: 1 A 1 → 1, 1 A 0 → 0, 0 A 1 → 0 , 0 A 0 → 0
• XOR: 1 X 1 → 0, 1 X 0 → 1, 0 X 1 → 1 , 0 X 0 → 0
