What is a computational graph in deep learning?
A computational graph is a 6-tuple 〈n, l, E, u1 ...un,d1 ...dn,fl+1 ...fn〉 where: • n is an integer specifying the number of vertices in the graph. l is an integer ...
This is an example of the backpropagation technique. In practice, we usually don't construct a separate computational graph object to represent the gradient.
