SDL1 3支援多個視窗

在sdl1.2中是不支援多視窗的，而還沒有正式發布的、非穩定狀態下的sdl1.3是完全支援多視窗的。

Struts2支援表單多物件提交

struts2對集合型別的轉換提供了很好的支援，你可以用集合物件來儲存表單提交的資料，這對提交多個相同類別的資訊將非常有用 1 物件中宣告屬性objectlist action中宣告list 2 頁面迴圈list list objectlist as object assign index obje...

3 支援向量機

3.1 本質 基本模型是定義在特徵空間上的間隔最大的線性分類器。核技巧使之成為實質上的非線性分類器。學習策略是間隔最大化，可形式化為求解凸二次優化問題。等價於正則化的合頁損失函式的最小化問題。學習演算法是求解凸二次規劃的最優化演算法。理解支援向量機可以從簡至繁推進 線性可分支援向量機 硬間隔svm ...
