If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."

However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …

How does PyTorch calculate gradient: a programming perspective

#artificialintelligenceJul-18-2021, 00:35:41 GMT

PyTorch uses the autograd package for automatic differentiation. For a tensor y, we can calculate the gradient with respect to input with two methods. After we do the .backward(), PyTorch generates a Dynamic Computation Graph when the forward function of network is called. We borrow a toy example from here.
