@martinraison @ebetica thanks for the answers.
I’ve just noticed that there is also an implementation of SparseLinear here 39. Can I use those
c functions to create a Function which will simply call self._backend.SparseLinear_accGradParameters, just like Embedding Function does (link 6)? Or there is some catch here?
I know that You guys probably have SparseLinear module on your roadmap, but I wanted to play around with it during the weekend, hence the question.
