As discussed in #6361 we weren't sure why fairseq's polynomial_decay_schedule power default was 1.0, and decided to go with 2.0 as the latter does something polynomial.

I got the devs at fairseq to answer this question: facebookresearch/fairseq#2466 (comment)

This is based on the original BERT code, which implemented a linear decay via a polynomial schedule with power=1.0: https://github.com/google-research/bert/blob/f39e881b169b9d53bea03d2d341b31707a6c052b/optimization.py#L37

So, perhaps we do the same or we don't.

If we don't - then the doc needs to be fixed that the default is power=2.0 as currently it says 1.0 - my mistake. If we do (this PR), then the doc is already correct.

Thanks.

I have no strong opinions on the default, so let's use the same as FAIR.
