The description states:
Follow this with dropout, using a keep rate of 0.8
Yet, the valid function seems to require Dropout(0.8), where 0.8 is the drop rate.
A “keep rate” of 0.8 would imply a “drop rate” of 0.2 ?
I think “keep rate” is a typo, it should be just “rate”. The grader expects you to use “Dropout(0.8)”.
I’ll submit a support ticket so the course staff will investigate it.
