Question 17

+1 markOne or more correct options

Which statements are true ?

Select all that apply.

  1. A

    Soft attention is differentiable and can be trained with backpropagation.

  2. B

    Hard attention often needs sampling + REINFORCE (or similar) due to non- differentiability.

  3. C

    Soft attention significantly reduces the computational complexity of the forward pass compared to Hard attention.

  4. D

    Cross-attention can align decoder queries to encoder keys/values (e.g., words attending to image regions).
