Question

PS 4: What is the difference between the build_coder function and the build_encoder function? They both produce the same output. The hint says I need to use build_coder in build_encoder, but that seems like repeating the same thing to me.

Answer 1

As far as I remember, not much, although I guess it's useful to differentiate between the encoder and the decoder function by naming them differently (although they're pretty much identical in what they actually do).

Answer 2

They do the same thing. On these problem sets there is room for improvement of the given code and implementation, which is another reason why I prefer a non-graded approach to these courses.

Answer 3

Near as I can tell, none. Neither build_encoder or build_decoder are present in the solution.
