※ 引述《rafan (@[email protected]"""")》之銘言: : ※ 引述《mercurial (多變)》之銘言: : : I use the same parameters... : : what are experiment logs?? : I mean what are the objective values you get : from both methods? I run sonar data, and set c=1, r=1/60 my hw5 program got -121, and there are many different values for alpha, such as 0, 1, 0.24... however, hw5 doesn't consider the constraint, sum(yi*alpha_i)=0 my hw7 program got -193. again, I entered into infinite loop, but I stoped when the optimal value converges to a stable value. however, all the alpha equal to 0 or 1 and sum(yi*alpha_i)=0 that means the alpha satisify all the constraints I don't understand why adding one more constraint gets better optimal value. maybe my hw5 program is wrong. but my result of hw5 is the same with the professor's. I think I don't fully understand the whole procedure. I just copied down what the professor wrote on board, and implemented them to programs. that's why I couldn't figure out why I got such results. Is is because of bugs or because of the different rules of these two methods? I totally have no idea.... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.135.188.92 ※ 編輯: mercurial 來自: 220.135.188.92 (11/09 01:19)
