This post explains what pct_start
means very well. But I have trouble finding how to choose pct_start
. What impact does pct_start
have on model training? Why was it set to a different value from the default 0.3
in these notebooks:

- https://github.com/fastai/course-v3/blob/master/nbs/dl1/lesson7-human-numbers.ipynb
Thanks.
