THE LOGIC MACHINE

McCulloch-Pitts Neural Networks

1943 - The Foundation of Artificial Intelligence

Build Logic Gates with Artificial Neurons

McCulloch's Jots and X's

Warren McCulloch taught children logic using simple symbols:

•
Jot (AND)
✓
×
X (OR)
✓
~
Not (NOT)
✓
∧
Chain
✓

Build these same operations using artificial neurons!
