財經時間序列預測：使用R的計量與機器學習方法

為了解決python /r /n的問題，作者何宗武 這樣論述：

　　本書為進階的教材，需要經濟計量方法和矩陣代數的基礎。時間序列預測是統計學裡非常實用的工具，不論是分析投資組合的數據、全球總經和金融市場，以及預測景氣循環變動等等，可以用過去的數據資料，預測未來趨勢，是可以符合實際決策需要的實用能力。   　　書中並介紹機器學習方法，機器學習不是指特定估計方法，學習指的是如何在資料結構中運算，以追蹤最小預測誤差的方法獲得最佳預測(tuning)。我們應用機器學習演算法訓練歷史資料，執行特徵萃取(features extraction)，再測試預測表現。依此建立一個可預測未來的模型，作為決策之用。   　　使用R語言進行時間序列預測是本書的一大特點，R語言

是統計學中普及且容易上手的分析工具，書中針對一個個資料分析步驟進行深度解說，教給讀者進行預測與評估的最實用方法。

植基於5G多型態網路環境下使用區塊鏈技術進行身份驗證之研究

為了解決python /r /n的問題，作者高一陳 這樣論述：

5G的巨量通訊和低延遲通訊兩個特性，對於企業加速數位轉型時的應用非常重要，尤其是現在已經進入工業4.0時代，網路通訊品質格外重要，結合5G通訊特性及Wi-Fi 6優點的多型態網路，儼然已成為網路新時代的架構，惟本國目前的5G架構因為成本建置考量，尚屬於NSA架構，或許未來硬體更成熟，成本較低時，或許也會採用SA。使用區塊鏈3.0的技術主要是它針對物聯網有提供相當完整及方便的函數庫，而且區塊鏈3.0的特性是不用挖礦，沒有礦工角色，而且越多人使用，驗證速度越快，與區塊鏈1.0或2.0技術不一樣。將傳統的紙本證件，使用區塊鏈3.0技術，將它轉成電子化資料，只要儲存認證完成的交易代碼，就能夠透過此代

碼找到相關原始資料，傳統書面證書或者紙本資料，轉為具有區塊鏈技術架構的數位證書，已經是未來的趨勢。利用IOTA技術提供5G驗證與Wi-Fi 6驗證結合，透過Python 跟C# .Net電腦語言，實作出應用區塊鏈3.0技術來驗證物聯網設備在多型態網路的環境下，可以達到驗證效果，這是本研究的主軸，跳脫傳統的驗證方式，且更具安全性的驗證。

布里斯洛中間體自由基反應機制之理論研究

為了解決python /r /n的問題，作者謝明修 這樣論述：

含氮雜環卡賓（N-heterocyclic carbene）催化之化學反應中，布里斯洛中間體（Breslow intermediate）扮演重要的催化角色。布里斯洛中間體能以親核基（nucleophile）或自由基（radical）之形式參與反應。本論文探討布里斯洛中間體之自由基特性及形成機制（mechanism），其自由基可從氫自由基轉移或直接氧化形成。安息香縮合反應（benzoin condensation）中，布里斯洛中間體將氫原子轉移至苯甲醛（benzaldehyde）以形成自由基，此自由基可結合形成安息香產物，或排除反應之副產物，使其重新進入催化反應。唯此路徑之反應能障高於傳統非自

由基路徑。此研究亦探討四種布里斯洛中間體之不同電子組態的位能面。其中烯醇鹽（enolate）形式能產生偶極束縛態（dipole-bound state），此為產生自由基之新路徑；拉電子基（electron-withdrawing group）以及立體障礙基（bulky groups）可穩定基態。另外，我們亦研究布里斯洛中間體之碎片化（fragmentation）與重組（rearrangement）。布里斯洛中間體之催化反應可能因其碳氮鍵斷裂而中止，形成碎片。我們證實其反應中可以形成自由基，亦可形成離子。反應趨向之路徑與布里斯洛中間體之羥基的質子化型態有關。碎片化反應亦可視為轉酮醇酶（tran

sketolase）中之噻胺（thiamin）催化反應中之副反應；此研究證實轉酮醇酶透過限制布里斯洛中間體之結構與質子化型態，使其碳氮鍵斷裂需更高之反應能量，進而抑制此副反應。
