DLS1 week 4: forward and backprop, a[l-1] in a cache?

petril48 · July 25, 2021, 6:04pm

Hi,

In the lecture Forward and Backward Propagation, I have a question in the following slide.
so z[l], along with w[l] and b[l] need to be in a cache. How about and a[l-1]?, and thus all the a[l] for l in [1;L]?

Thank you so much,

Best

Yes, the A values are also included in the caches.
