Autograd¶ Autograd는 자동 미분을 수행하는 torch의 핵심 패키지로, 자동 미분을 위해 테잎(tape) 기반 시스템을 사용합니다. 순전파(forward) 단계에서 autograd 테잎은 수행하는 모든 연산을 기억합니다. 그리고, 역전파(backward) 단계에서 연산들을 재생(replay)합니다.

Apr 01, 2019 · You will understand the different types of differentiation that could be used in this process, and how PyTorch uses Autograd to implement reverse-mode auto-differentiation. You will work with different PyTorch constructs such as Tensors, Variables, and Gradients. Finally, you will explore how to build dynamic computation graphs in PyTorch.
