    Abstract: 普適提(Boosting)是近年來發展迅速且廣泛被應用於分類問題的方法之一，
    其特點是利用精確度較低或是較粗糙的分類方法(weak learner)為基礎，
    經由多次反覆分類之後，
    將其結果合併而提升分類的精確度。
    本研究為探討若是SVM, KNN, LDA等分類基底時，
    普適提是否仍然能夠達到改進的效果，
    或是會造成模型過適的情況(overfitting)。
    我們發現到普適提在訓練資料集(training set)與測試資料集(testing set)的解釋變數
    獨立且同分佈(independent identically ditributed)產生的情況下，
    無論用任何一種分類法則皆有造成模型過適的可能；
    但是，若訓練資料集與測試資料集的相關程度很高的情況下，
    則不會發生模型過適的情況，
    因此，欲探討不同相關係數以及分布類似的程度對測試資料集的結果有何影響。
