In sparseencoder-KL method, why is sparsity constraint applied on all fc layers across encoders and decoders?

Hi @syorami /Anyone,

As I understand it, the goal of sparse constraint is to enable only the "encoding" to be sparse. Why then is sparsity loss accumulated across every fc layer of both the encoder and decoder? Could you please let me know of this at the earliest if possible? If any reference to an article or text or blog that discusses this could suffice me too. Please help.

Thanks,
