no i was just curious. thanks for the answer
from chainrulescore.jl.
Both can be true: the non-existent field being a NoTangent()
or ZeroTangent()
, depending on the use case. And we had to pick a default. One could argue that ZeroTangent()
is the more appropriate choice, but it is probably not worth the effort to change it at this point, unless you have a concrete use case in mind? (In practice, the behaviour of ZeroTangent()
and NoTangent()
should be interchangeable.)
