Webforward ResNet in Section 3. We show that the top level (ﬁnal) output of a ResNet can be thought of as a layer-by-layer boosting method (deﬁned in Section 2). Traditional boosting, which ensembles “estimated score functions” or “estimated labels” from weak learners, does not work in the ResNet setting because of two reasons: (1 ... WebIntuitive understanding of backpropagation. Notice that backpropagation is a beautifully local process. Every gate in a circuit diagram gets some inputs and can right away compute two things: 1. its output value and 2. the local gradient of its output with respect to its inputs. Notice that the gates can do this completely independently without being aware of any of … party food pet animal
