WebJul 25, 2024 · One way to evaluate what happens under different weight initializations is to visualize outputs of each neuron as a dataset passes through the network. In particular, we’ll compare the outputs of subsequent layers of a Multi-Layer Perceptron (MLP) under different initialization strategies. An (M + 1) -layer MLP is the network that has an ...

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). Why are these new algorithms working so much better than the standard random initialization and gradient-based optimization of a supervised training criterion? Part of the answer may be
