Why We Need Non-Linear Activations

šŸ”¢ Linear Functions

Click to explore: Multiple linear layers still create linear functions

šŸŒŠ Non-Linear Functions

Click to explore: Non-linear activations enable complex patterns

The Fundamental Problem

āš ļø
Linear Limitations
No matter how many linear layers you stack, the result is still linear
āŒ
XOR Problem
Classic example that linear models cannot solve
āœØ
Non-Linear Solution
Activation functions enable universal approximation
