SNLI Why config.d_out is 4 in snli/train.py?
In SNLI, the unknown label in answers is removed. It becomes a 3-way classification, i.e., entailment, neutral, and contradiction.

Neural style transfer question
Hi, not sure if this is the right place to ask questions, but I'm working through the neural style transfer tutorial and am confused about something. What is the purpose of the `backward` method in `ContentLoss` and `StyleLoss`? If we remove the `backward` method, won't this work as well for the `closure` functio...

what is exactly batch_size in pytorch?
Sorry im new to this. I am not sure if I understand right. in pytorch it says: batch_size (int, optional) โ€“ how many samples per batch to load (default: 1). I know that, batch size = the number of training examples in one forward/backward pass. What does it mean that it says "how many **samples** per **batch** to l...
