WebMar 16, 2024 · 3. Breaking the Symmetry. We basically have two possible extreme choices for initializing the weights of a neural network: select a single value for all the weights in the network, or generate them randomly within a certain range. Best practices recommend using a random set, with an initial bias of zero. The reason lies in the need to “break ... Webdeep supervised neural networks, but with initialization or training schemes different from the classical feedforward neural networks (Rumelhart et al., 1986).
