How can we implement the same in pytorch ? I'm new to pytorch. I have gone through forums and found that we can custom initialize weights with,

Additionally, ICNR initialization for Conv2d should also help (possible ... This init scheme initializes weights to act similar to nearest ...

The second argument must be another inplace initializer such as torch.nn.init.kaiming_uniform_ (or functools.partial(nn.init.kaiming_uniform_, a=0.01) if you need to pass arguments to it). Note that this is for standard strided convolutions and strided transposed convolutions, not for combinations with the pixel shuffle layer (which is generally not needed ).

torch.nn.init.dirac_(tensor, groups=1) [source] Fills the {3, 4, 5}-dimensional input Tensor with the Dirac delta function. Preserves the identity of the inputs in Convolutional layers, where as many input channels are preserved as possible. In case of groups>1, each group of channels preserves identity. Parameters.

21.03.2018 · To initialize layers you typically don't need to do anything. PyTorch will do it for you. If you think about it, this makes a lot of sense. Why should we initialize layers, when PyTorch can do that following the latest trends. Check for instance the Linear layer. In the __init__ method it will call Kaiming He init function.

We can conclude that the Kaiming initialization indeed works well for ReLU-based networks. Note that for Leaky-ReLU etc., we have to slightly adjust the factor of in the variance as half of the values are not set to zero anymore. PyTorch provides a function to calculate this factor for many activation function, see torch.nn.init.calculate_gain .

Integrating the initializing rules in your PyTorch Model. Now that we are familiar with how we can initialize single layers using PyTorch, we can try to initialize layers of real-life PyTorch models. We can do this initialization in the model definition or apply these methods after the model has been defined. 1. Initializing when the model is ...
