SIREN in PyTorch
In this video I implement the SIREN. It was proposed in the paper "Implicit Neural Representations with Periodic Activation Functions". It is a feedforward neural network that is using the sine function as activations. This video focuses on a case where the input features are 2D and they represent coordinates of an image. I discuss multiple relevant topics like the weight initialization and higher order derivatives.
