在使用ADJUST 和 ICMARC 的特徵算法從最後實驗結果可以發現到特徵對於訊號 之前的差異性在變異數分析的結果是具有參考性質的,實驗當中的赫斯特指數不管在分 類器特徵挑選上還是變異數分析中得到的結果是屬於偏差的,儘管在一些情況中有得到 分類效果的提升,但得到效益很低,那麼我們可以知道利用變異數分析可以明確的發現 這種分析法對於訊號特徵的分析結果是很好的,在不同的分類器上儘管訊號之間具有差 異的比較性,但分類器對於特徵的適合性也會造成不一樣的結果,在學習分類器上隨機 森林、支援向量機、樸素貝葉斯對於訊號這種特徵是屬於較好的方式,雖然最後最好的 結果中沒有最鄰近演算法,但從實驗表格中可以發現最鄰近的分類沒有最好但普遍看來 都是不錯的。在資料挑選的時候,雖然在ADUST 和 ICMARC 個別挑選出雜訊有時出現 錯誤,但兩種訊號分類器一起使用挑選出的結果幾乎都是好的,極少數部分才會出錯,

兩種分類的方式有所互補可以讓分類效果更好,但也會隨著時間效益變低,多個方法代 表特徵越多,那我們在使用檢定的方式來做特徵的挑選,可以得到更高效益的特徵,在 使用分類器檢測學習效果的好壞,利用這樣的方式使能做出更有效益及更準確的訊號分 類器。
