                題目標題

                解釋對偶的劍氣沖天而起概念。

                難度:初級

                機器學習
                參考解析

                一個優∮化問題可以從兩個角度進行考察,一個是 primal 問題,一個是 dual
                問題,就是對偶問№題,一般情況下對偶問題給出主問題最優值的╱下界,在強對
                偶性成人讓開一條道立的情況下由對偶問題可以得@ 到主問題的最優下界,對〓偶問題是凸優化
                問題,可以進行較好≡的求解,SVM 中就是將 Primal 問題轉換不禁深深一嘆為 dual 問題進行
                求解,從而進一步▲引入核函數的思想。
