Forward computes the values. Backward multiplies the local slopes, one step at a time.

Computation graphs · Every calculation as a graph of small operations. About 30 minutes.
Other terms from the same lesson
- local derivative: How one small step in a computation graph changes its output when its input moves a little. Backpropagation multiplies these along the path.
- topological order: An order for the steps of a graph where every step comes after the steps it depends on.
