I have some question about the hw 8-2:
(1).
In the first part, teacher Lin asked us to prove
when K=I
alpha* = e - (y'e/l)y
but since 2 > alpha* > 0
does it mean that we don't need to consider the first constraint :
0 <= alpha_i <= C
and could we assume that C >= 2 ?
(3).
In the third part, teacher Lin asked us to prove
when alpha_i > 0, y_i(W'x_i + b) = 1
my question is why we need to specify whether alpha_i is greater than one,
alpha_i already have to be greater than one (because of the constraint..).
