Study Notes

Introduction to PyTorch's Automatic Differentiation Engine - torch.autograd

  • PyTorch's automatic differentiation engine, torch.autograd, powers neural network training.
  • Neural networks consist of nested functions executed on input data, defined by parameters stored in tensors.
  • The two steps of training a neural network are forward propagation and backward propagation.
  • Forward propagation makes a guess about the correct output and collects the derivatives of the error with respect to the parameters of the functions (gradients) in backward propagation.
  • Autograd calculates and stores the gradients for each model parameter in the parameter's attribute during backward propagation.
  • We register all the parameters of the model in the optimizer, which adjusts each parameter by its gradient stored in autograd's attribute.
  • Autograd tracks operations on all tensors that have their flag set to True for gradient computation.
  • The output tensor of an operation will require gradients even if only a single input tensor has requires_grad=True.
  • In finetuning, we freeze most of the model and typically only modify the classifier layers to make predictions on new labels.
  • Autograd keeps a record of data and all executed operations in a directed acyclic graph (DAG) consisting of Function objects.
  • The graph is recreated from scratch after each call, allowing control flow statements in the model.
  • Exclusionary functionality is available in torch.no_grad() for tensors that don't require gradients.
