Backpropagation

Learn the Chain Rule through a simple computation graph:
f = (x + y) · z

Inputs

x -2.0
y 5.0
z -4.0

Playback

Forward Pass (Values)
Backward Pass (Gradients)
Local Derivatives

Step 0: Initialization

Set the inputs using the sliders on the left. Click "Next" to begin the forward pass and compute the final output.

f(x, y, z) = (x + y) * z
