Webb6 aug. 2024 · Kaiming initialization shows better stability than random initialization. Understand fan_in and fan_out mode in Pytorch implementation. nn.init.kaiming_normal_() will return tensor that has values sampled from mean 0 and variance std. There are two ways to do it. One way is to create weight implicitly by creating a linear layer.
