※ 引述《Evenroll (研二不是應該很清閒嗎？)》之銘言：
: 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 ?
You can assume that and clearily state it in the homework.
: (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..).
I think you mean alpha_i > 0, not 1?
