Seq2seq: Reversing the Source Sentence
Beginner
The problem, from first principles
Sutskever et al. (2014) found that reversing the source sentence makes learning easier, because the first words of the input end up close to the first words of the output. Only the input is reversed; the target is left alone.
From theory to code
Implement reverse_source(tokens), which returns the tokens in reverse order as a new list.
Constraints
- The input may be a list or a tuple.
Hints
Hint 1
Slice with a step of -1, after converting to a list.
