What does .view do in this basic model?

Specifically, what do the parameters mean?

From the docs:

Returns a new tensor with the same data as the self tensor but of a different shape.
The returned tensor shares the same data and must have the same number of elements, but may have a different size. For a tensor to be viewed, the new view size must be compatible with its original size and stride, i.e., each new view dimension must either be a subspace of an original dimension, or only span across original dimensions …

In other words: view is similar to reshape, but doesn’t trigger a copy of the tensor.
The values passed to view are used as the shape of the view.
