    Title: 應用倒傳遞類神經網路於P2P借貸投資報酬率預測之研究——以Lending Club為例

    Abstract: 金融科技因為能大幅降低金融活動中的交易成本與門檻,同時打破傳統金融交易資訊不及時的情況,因此能創造以往未有的商業價值。其中P2P Lending即透過電子化技術創造交易平台媒合資金提供者與需求者的微型授信服務,因為省去傳統金融機構中介的成本,故能提升供需雙方效益。然而特殊的營運方式使資金提供者須承擔更高風險,實際上P2P Lending亦曾發生重大詐騙與倒帳事件,因此使英美中政府加強監管,相較之下,我國仍維持不納入金融監管原則,因此本研究試圖以Lending Club具有代表性的案例,提供投資者選擇投資標的的建議。
    本研究搜集Lending Club自2007年至2011年42538筆已發行之借貸,在111個變數中使用 Pearson Correlation以及Information gain,並輔以文獻回顧進行變數選擇挑選22個變數。在搭配Dropout技術與透過網格搜索分析最佳化演算法、批次訓練樣本數、訓練次數等參數配置後,本研究訓練得到在測試集準確度達76%的類神經網路模型。經模擬後發現,類神經網路ROI的平均值為9.40,高於對照組7.02,經檢定驗證此差異結果可以採信,因此類神經網路能有效的給予投資人有效的投資建議。
