16.09.2019 · He initialization When your neural network is ReLU activated, He initialization is one of the methods you can choose to bring the variance of those outputs to approximately one (He et al., 2015). Although it attempts to do the same, He initialization is different than Xavier initialization (Kumar, 2017; He et al., 2015).

Also known as He initialization. Parameters tensor – an n-dimensional torch.Tensor a – the negative slope of the rectifier used after this layer (only used with 'leaky_relu') mode – either 'fan_in' (default) or 'fan_out'. Choosing 'fan_in' preserves the magnitude of the variance of the weights in the forward pass.
