研究方向
The issue requires implementing backpropagation through the 'unfold' and 'recurse' functions in Gen.jl. The specific lines are in src/modeling library/unfold/unfold.jl around line 40-41 and src/modeling library/recurse/recurse.jl around line 130-131. A contributor should first understand how backpropagation is implemented for other functions in the codebase. The issue has been open since 2019 with no recent activity, so it is advisable to re engage with maintainers to clarify expected behavior and ensure the feature is still desired.
