WebJul 1, 2024 · As we go backward through the computation graph, we can compute de/dc without knowing anything about dc/da or dc/db as e = g (c, d) comes after a and b. Yes, that is the critical part. In order for autograd to work, every supported op must have a backward function (or more than one depending on the number of inputs) defined for this purpose. http://www.iotword.com/3369.html
