Regarding the effect of the backprojection

[cdb342]

I conducted an ablation study where I set 'backward_projection' to None (while keeping other configurations at their default settings). The results showed that the availability of this module did not have a significant impact on the results. Here are the results for epochs 2 and 4:

epoch	2	4
with backward_projection	36.74	38.60
without backward_projection	36.83	38.67

Can you please share any ablation results you may have for this module?
