This website helps you learn what PyTorch functions do by showing them in action. PyTorch itself is an open-source machine learning library, and per Wikipedia "used for applications such as computer vision, deep learning research and natural language processing, originally developed by Meta AI and now part of the Linux Foundation umbrella." In order to benefit from this website you need to run through the examples and then actually think about what's happening in the simulation. torch.cat, for example, concatinates one tensor (which is a data strructure like an array or matrix) with another - and you can see them put together, one after another. Torch.minimum will compare two tensors and take the minimum value for each element. Do this sort of stuff with very large datasets and you get machine learning.
