WitrynaThis initializer is designed to keep the scale of the gradients roughly the same in all layers. In uniform distribution this ends up being the range: x = sqrt(6. / (in + out)); [-x, x] and for normal distribution a standard deviation of sqrt(2. / (in + out)) is used. Args: uniform: Whether to use uniform or normal distributed random ... Witryna30 kwi 2024 · Xavier initialization is employed for layers that utilize Sigmoid and Tanh activation functions, while Kaiming initialization is tailored for layers with ReLU activation functions. Incorporating these weight initialization techniques into your PyTorch model can lead to enhanced training results and superior model performance. ... import … rbc michigan
