"WebbWhen the diode is reverse biased, as depicted in figure 5.6, the gap increases, and very little current flows across the junction (until eventually in this example at ~ 6.2V field break down occurs). Conversely, a forward biased configuration decreases the gap, approaching zero for an external voltage equal to the gap voltage, and current can flow easily. " - To flow backward is called

WebbBy default, pytorch expects backward () to be called for the last output of the network - the loss function. The loss function always outputs a scalar and therefore, the gradients of the scalar loss w.r.t all other variables/parameters is well defined (using the chain rule).
