二元主體學習技術研究與張量流實作

Bipartite Majority Learning with Tensors

指導教授 : 郁方

摘要


由於AlphaGo和人工智慧機器人的顯著成就,機器學習領域受到了廣大的關注。從那時起,機器學習技術被廣泛用於計算機視覺,信息檢索和語音識別。但是,資料集當中不可避免地會包含統計上的異常值或錯誤標記。這些異常資料可能會干擾學習的有效性。在主體模式發生變化的動態環境中,將異常與主體資料區分開來變得更加困難。本研究解決了關於分類數據在抗性學習中的研究問題。具體來說,我們提出了一種有效的二元主體學習算法,並使用張量進行數據分類。我們採用抵抗性學習方法來避免異常資料對模型訓練造成重大影響,然後迭代地對主體資料進行二元分類。本研究中的學習系統使用TensorFlow API實現,並使用GPU加速模型訓練過程。 我們對惡意軟體分類的實驗結果說明,與以前的抗性學習演算法相比,我們的二元主體學習演算法可以顯著縮短訓練時間,同時保持有競爭性的分類準確度。

並列摘要


A great deal of attention has been given to machine learning owing to the remarkable achievement in Go game and AI robot. Since then, machine learning techniques have been widely used in computer vision, information retrieval, and speech recognition. However, data are inevitably containing statistically outliers or mislabeled. These anomalies could interfere with the effectiveness of learning. In a dynamic environment where the majority pattern changes, it is even harder to distinguish anomalies from majorities. This work addresses the research issue on resistant learning on categorical data. Specifically, we propose an efficient bipartite majority learning algorithm for data classification with tensors. We adopt the resistant learning approach to avoid significant impact from anomalies and iteratively conduct bipartite classification for majorities afterward. The learning system is implemented with TensorFlow API and uses GPU to speed up the training process. Our experimental results on malware classification show that our bipartite majority learning algorithm can reduce training time significantly while keeping competitive accuracy compared to previous resistant learning algorithms.
