金融互換工具定價模型之研究 / The Pricing Model of Financial Swaps

陳明彬, Ming-Bin Chern Unknown Date (has links)
本論文主要目標為發展金融互換的定價模型。既是欲建立量化模型,首要 工作在於對量化對象 --- 金融互換工具的實際特性, 實務上的運作,有 瞭解與掌握,再輔以必要的數量基礎,方不致於`` 失真 '' 。本文共分 五章首章為緒論,第二章為對金融互換工具的全盤認識,試圖由金融互換 的契約切入,進而歸納分類要件,演化及最終種類,最後提出定價時的幾 個思維面向(Dimensions )。第三章為文獻回顧,指出金融互換定價模型 的基礎,為建立在具浮動利率金融工具的定價模型上。 第四章為發展理 論模型基礎及數值分析結果。第五章為結論。

應用神經網路於金融交換與Black-Scholes定價模式之探討與其意義分析 / A study and analysis of applying neural networks to the financial swapa and the Black-Scholes pricing model

林義評, Lin, Yi-Ping Unknown Date (has links)
本篇論文旨在分析神經網路學習績效,並提出一套學習演算法,結合倒傳遞網路(BP)與理解神經網路(RN),命名為RNBP,這套學習演算法將與傳統的BP做比較,以兩個不同的財務金融領域的應用,一個是選擇權上Black-Scholes訂價模式的模擬,一個是金融交換上利率的預測。主要績效的評估準則是以學習的效率與模擬、預測的準確度為依據。 此外,本論文的另一個重點是提出一套對於神經網路系統進一步分析的方法與工具,敏感度分析(Sensitivity Analysis)與滯留區(Dead Region)分析,藉以瞭解神經網路系統是否具有效地良好學習或被一般化的能力,從神經網路的角度來說,這也是BP與RNBP的另一個績效比較標準。本研究的結果顯示RNBP在預測準確度上較BP為優良,但是在學習效率與預測能力的穩定性上並沒有呈現一致性的結論;此外,敏感度分析與滯留區分析的結果也幫助神經網路在應用領域上有更深入的瞭解。 在過去,神經網路的應用者往往忽略了進一步瞭解神經網路的重要性與可行性,本論文的貢獻在於藉由分析神經網路所學習的知識,幫助應用者進一步瞭解神經網路表達的訊息在應用領域上所隱含的實質意義。 / The study attempts to analyze the learning performance of neural networks in applications, and propose a new learning procedure for the layered feedforward neural network systems, named KNBP, which binds RN and BP learning algorithms. Two artificial neural networks, BP and KNBP, here are both applied to two financial fields, the simulation of Black-Scholes pricing model for the call options and the midrates forecasting in financial swaps. The explicit performance comparison between the two artificial neural network systems is mainly based on two criteria, which are learning efficiency and forecasting effectiveness. Then we propound a mathematical methodology of sensitivity analysis and the dead regions to deeply explore inside the network structures to see whether the models of ANNS are actually well trained or valid, and thus setup an alternative comparable criterion. The results from this study show that RNBP performs better than BP in forecasting effectiveness, but RNBP obtains neither a consistent learning efficiency in cases nor a stable forecasting ability. Furthermore, the sensitivity analysis and the dead region analysis provide a deeper view of the ANNs in the applied fields. In the past, most studies applying neural networks ignored the importance that it is feasible and advantageous to obtain more useful information via analyzing neural networks. The purpose of the research is to help further understanding to the information discovery resulted from neural networks in practical applications.
