Can I test forward accumulation?

[take0212]

Thank you for the great work!

Can I test forward accumulation?
Your paper includes a performance comparison betwen backward accumulation and forward accumulation in Table 2.
I can test backward accumulation using your code, but I cannot test forward accumulation using it.

Do you have a code or pre-trained model for forward accumulation?
Is it possible to test forward accumulation using a pre-trained model for backward accumulation?
It is the best to test forward accumulation without retrain or fine tuning.

Thanks in advance.
