Implementing Custom Loss Functions in PyTorch
WebPyTorch: Custom nn Modules A third order polynomial, trained to predict y=\sin (x) y = sin(x) from -\pi −π to \pi π by minimizing squared Euclidean distance. This implementation defines the model as a custom Module subclass. WebThis implementation computes the forward pass using operations on PyTorch Tensors, and uses PyTorch autograd to compute gradients. In this implementation we implement our own custom autograd function to perform P_3' (x) P 3′(x). By mathematics, P_3' (x)=\frac {3} {2}\left (5x^2-1\right) P 3′(x) = 23 (5x2 − 1) WebThis implementation uses Pyro's blackbox SVI function with the default ELBO loss. This is slower than the TensorFlow implementation which uses a custom loss function with an analytic solution to the KL divergence term. Currently the code is not set up to use a GPU, but the code should be easy to extend to improve running speed horario bus almeria san jose
