View source for Example of ReLU Activation Function

== ReLU (Rectified Linear Unit) Example ==

The ReLU function is defined as:

:<math>f(x) = \max(0, x)</math>

This means:
* If ''x'' is '''positive''', it stays the same.
* If ''x'' is '''negative''', it becomes ''0''.

=== Real Number Examples ===

{| class="wikitable"
! 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! 🤖✨
