History of Neural Networks - Key Milestones

๐ŸŒ… Golden Age
1943
๐Ÿง  First Mathematical Model
McCulloch and Pitts create the first mathematical model of a neural network, laying the foundation for artificial neurons with binary threshold logic.

๐Ÿš€ Renaissance
1986
๐Ÿ”„ Backpropagation
Rumelhart, Hinton, and Williams popularize backpropagation, enabling training of multi-layer networks and solving the XOR problem that ended the golden age.
