Nn.linear weight bias

WebbIn your Neural Network, the self.hidden = nn.Linear(784, 256) defines a hidden (meaning that it is in between of the input and output layers), fully connected linear layer, which takes input x of shape (batch_size, 784), where batch size is the number of inputs (each of size 784) which are passed to the network at once (as a single tensor), and transforms … Webb17 dec. 2024 · Whether the √5 factor is intentional or not, the documentation is wrong for the weights. Linear While for bias k = 1/in_features is true, for the weight, k = 6/in_features assuming pure Kaiming, or k = 6 * 5/in_features at the moment. Convolution Same remark Closing thoughts
