Alignment not coming properly

Hi,

I have trained a transformer base model for English- Hindi pair. On 300K steps, I infer the translation with “with_alignmet = hard” flag on.

The alignments are not coming properly.

For e.g.
The translated o/p: उसने भी राक्षस देखे । ||| 4-0 4-1 4-2 4-3 5-4

source sent: He too saw the monsters .

In above, alignment is totally wrong, but the translation is correct though.

Can you please help me in getting the correct alignments?

Thanks,
Sriram

Hi,

Did you train with guided alignment? If not, the Transformer model can’t produce usable alignment on its own.
