摘要


在現今單機電腦環境已經無法有效率的分析大量資料的同時,Hadoop運算平台之可儲存與分析之特性有著明確的重要性。對於大量資料分析過程而言,資料探勘的演算法應用是其中重要的一環。而本次研究為了解決二元分類演算法SVM之時間複雜度過高的問題,改良一二元分類演算法,於分散式平行化運算框架中達到加速篩選分類資料的效果。主要利用MapReduce程式框架之平行化處理特性實現此演算法並成功運行於Hadoop運算平台上,在使用相同資料集進行訓練分析的情形下,大幅降低了執行運算時間。

並列摘要


With increased amount data today,it is hard to analyze large data on single computer environment efficiently,the hadoop cluster is very important because we can save and large data by hadoop cluster. Data mining plays an important role of data analysis.Because time complexity of the binary-class classification SVM algorithm is a big issue,we design a parallel binary SVM algorithm to slove this problem,and achieve the effect of classifying appropriate data. By leveraging the parallel processing property in MapReduce ,we implement multi-layer binary SVM by MapReduce framework,and run on the hadoop cluster successfully. By designing different parameters of hadoop cluster and using the same data set for training analysis, it shows that the new algorithm can reduce the computation time significantly.
