Presentation Transcript

  1. Cloud Computing project NSYSU Sec. 3 Demo

  2. Outline • Query Dependent Ranking SVM • Implementing MapReduce on Ranking SVM • Experiments NSYSU EE IT_LAB

  3. 本季目標 • Build a scoring and ranking model using machine learning techniques. NSYSU EE IT_LAB

  4. 研究方法 • 利用分散式運算平台實現結合機器學習技術之網頁評分與排名學習模型之建立。 • 利用MapReduce技術改寫訓練與測試模型使其對於大量資料之處理效率提昇並驗證其正確性。 NSYSU EE IT_LAB

  5. Query Dependent Ranking SVM • A query-base ranking model. • Each training query builds a ranking model. • Testing query chooses the models which have the higher scores. NSYSU EE IT_LAB

  6. Implementing MapReduce on Ranking SVM Query q1 : …. qn+1 : …. q: …. … q2 : …. qn+2 : …. q: …. … … … Map Model 1 Model n+1 Model … Model 2 Model n+2 Model … … … Model 1 Training process Total Model Model 2 NSYSU EE IT_LAB …

  7. Implementing MapReduce on Ranking SVM Testing process Query score score score score Map … … … … score score score score NDCG NDCG Reduce … … NDCG NDCG OUTPUT OUTPUT NSYSU EE IT_LAB …

  8. Experiments NSYSU EE IT_LAB

  9. 未來目標 • 提供一個使用者文字query查詢輸入介面。 • 利用結合機器學習技術之網頁排名模型給予使用者較高相關程度之排序網頁列表。 NSYSU EE IT_LAB
