Hi I think the attention weight should be written as $\alpha^{…}$ instead of $a^{…}$?

This is the corresponding line in the assignment:  
“𝑒⟨𝑡,𝑡′⟩ is then used when computing the attention 𝑎⟨𝑡,𝑡′⟩ that 𝑦⟨𝑡⟩ should pay to 𝑎⟨𝑡′⟩.”

Hi It’s the “neural machine translation” assignment from week 3. I think the attention weight should be 𝛼⟨𝑡,𝑡′⟩ instead of 𝑎⟨𝑡,𝑡′⟩, a small typo
