Example of ReLU Activation Function

ReLU (Rectified Linear Unit) Example

The ReLU function is defined as:

$f(x)=\max (0,x)$

This means:

• If x is positive, it stays the same.
• If x is negative, it becomes 0.

Real Number Examples

Input (x)	ReLU Output f(x)
-3	0
-1	0
0	0
2	2
5	5

In this table:

• Negative numbers become 0 🚫
• Positive numbers pass through ✅

This makes ReLU very fast and useful for deep learning models! 🤖✨
