    Abstract: 本研究致力於透過液相層析串聯質譜(LC-MS/MS)自動識別與分析醣鏈結構。應用資料探勘和機器學習技術,我們分析了斑馬魚腦與卵巢組織的數據集。相較於人工分析,我們的方法顯著提高了從龐大數據中定位樣本的效率,證明了其可行性。特別是,我們的方法大幅縮短了生物學家進行分析的時間,將原本需要30小時的任務縮減至幾秒內完成。這一成就強調了我們方法提升效率的潛力。最終,我們驗證了隨機森林模型在此問題上為各類別提供了最合適的模型,並具有跨組織樣本識別能力。它能有效識別訓練數據中未出現的組織中的醣鏈,證明了這一工具的實用應用性。總之,這項研究為深入理解和分析質譜儀產生的醣數據提供了一種快速且實用的工具,為未來研究的應用和方法的改進開辟了新的途徑。
    This study focused on automatically identifying and analyzing glycan structures based on liquid chromatography/tandem mass spectrometry (LC-MS/MS). By applying data mining and machine learning techniques, we analyzed the zebrafish Brain and Ovary tissue datasets. Our methods enhanced the efficiency of targeting samples from vast data compared to human efforts, thus demonstrating their viability.

    Specifically, our approach has significantly expedited the time-consuming analysis process for a biologist, reducing tasks that traditionally took 30 hours to mere seconds. This achievement underscores the efficiency-enhancing potential of our method.
    Ultimately, we have validated that the Random Forest model in this problem offers a generally most suitable model for various categories and possesses cross-tissue sample identification capabilities. It can effectively recognize glycans in tissues not present in the training data, proving the practical applicability of this tool.
    In summary, the research provides a rapid and pragmatic tool for a deeper understanding and analysis of glycan data produced by mass spectrometers, promising new avenues for future research application and refinement of this method.
