Hello friends,

I the ‘Attention Model’ video at time 6:11, a formula is presented for calculating attention variable (alpha<t, t’>). Although the formula is understandable, it can also be confusing, since the parameter t’ (t-prime) which is used as an index counter in the denominator, is the same as the one which is written on the left-hand side and also the numerator, and the two do not seem to be related to each other. Maybe using some different variable like “j” is more suitable to be representative of the summation index.
