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..). -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.25.136 ※ 編輯: Evenroll 來自: 140.112.25.136 (11/13 09:13)
