實驗室介紹

一起的小旅遊、一起的KTV、一起的溫馨節慶當然還有一起的努力!


1. 研究內容:

以機器學習演算法進行數值預測、語意分析、主題模型建立,並架構推薦系統。研究過程包含文獻探討、資料前處理、資料庫操作、演算法實作、訓練與測試,進一步以分散式架構佈署、執行系統。若無程式技巧也無需太擔心,可於碩一時加強練習,實作演算法時可以函式庫輔助,實驗室同學們也很樂意互相交流學習!


2. 開會:

每周固定一次全實驗室開會,輪流報告近期新興研究與方法、和研究方向相關的論文,平日也可自由與老師、學長姐討論。


3. 課業與研究:

  • 課業:資料探勘研究與實務、資料探勘專題是必修課程,其他課程不拘,符合所上修業規章即可
  • 外所相關課程:機器學習(電信所)、深度學習(電信所)、巨量資料分析(資工所)...等
  • 研究:碩一時,閱讀相關論文、增強程式能力,碩一下大致確定研究方向,碩一暑假發想大略的研究計畫。碩二時,文獻探討、資料處理、實驗實作


4. 活動:

  • 出遊:老師、同學開車出遊,騎腳踏車、親近大自然為主。期中約有1-2次,暑期會有一次兩天一夜的旅行。
  • 唱歌:去KTV唱歌! 期中約1-2次,年末尾牙1次。
  • 聚餐:籌劃小活動、吃吃喝喝! 特殊節日舉行,例如:慶生、聖誕節、歷屆學長姐回娘家、冬令進補...等。


5. 日常:

會一起買午晚餐(歡迎自備環保碗筷!),不定期聚餐、玩桌遊,實驗室感情融洽~
