Hi,
In the encoder-decoder sequence to sequence model, why there has to be a eos token for the encoder input?
For decoder, sos token is important in the autoregressive formulation since you get a token and the context to predict the next token and eos is required to stop, but the encoder doesn’t require an eos right?
The tutorial here says you need eos token in both encoder and decoder input: https://pytorch.org/tutorials/intermediate/seq2seq_translation_tutorial.html 17
