Among used machine learning methods, the gradient descent method is widely used to train various classifiers, such as Back-propagation neural network and linear text classifier. However, the gradient descent method is easily trapped into a local minimum and slowly converges. Thus, this study presents a gradient forecasting search method based on prediction methods to enhance the performance of the gradient descent method in order to develop a more efficient and precise machine learning method for Web mining.However, a prediction method with few sample data items and precise forecasting ability is a key issue to the gradient forecasting search method. Applying statistic-based prediction methods to implement GFSM is unsuitable because they require a large number of data items to model a prediction model. In the contrast with statistic-based prediction methods, GM(1,1) grey prediction model does not need a large number of data items to build a prediction model, and it has low computational load. However, the original GM(1,1) grey prediction model uses a mathematical hypothesis and approximation to transform a continuous differential equation into a discrete difference equation in order to model a forecasting model.

其中梯度法是一个最常被使用来实现机器学习的方法之一，然而梯度法具有学习速度慢以及容易陷入局部最佳解的缺点，因此，本研究提出一个梯度预测搜寻法则(gradient forecasting search method， GFSM)来改善传统梯度法的缺点，用来提升一些以梯度学习法则为基础的分类器在资讯探勘上的效率与正确性；而一个所需资料量少、计算复杂度低且精确的预测模型是梯度预测搜寻法能否有效进行最佳解搜寻之关键因素，传统统计为基础之预测方法的缺点是需要较大量的数据进行预测，因此计算复杂度高，灰色预测模型具有建模资料少且计算复杂度低等优点，然而灰色预测理论以连续之微分方程式为基础，并且透过一些数学上的假设与近似，将连续之微分方程式转换成离散之差分方程式来对离散型资料进行建模及预测，这样的作法不尽合理，且缺乏数学理论上的完备性，因为在转换过程中已经造成建模上的误差，且建模过程仅考虑相邻的两个资料点关系，无法正确反应数列未来的变化趋势。

In succession, in order to further illuminate the validity of the disgorgement of corporation, this part, based on the comparatively all round review of the relationships between company and its officials, systematically analyses the theoretical basis of the disgorgement of corporation through the perspective of trust relationship, especially through the theory of duty of loyalty and its corresponding disgorgement in trust law.

He integrated the ideological essence of Confucianism, Buddhism and Taoism, and used the " Natural kindniss " to express the Innateknowledge ontology, which composed his ontology theory ; He took this "Natural kindniss" as the basic of his theory, to pursue the Humanity realm which claim "One Unity of All Things" and the Easefulness realm which claim "free and easy", he thought both the two realms have the same mean, and finally proposed the theory of realm. On the Effort theoretically, Luo Jinxi emphasized "all lays down and breaks the unreal ontology theory", to fit the Natural kindniss in the just moment .He fused the Effort and the Ontology , which made the two together. As to the theory of "Awakening Oneself by discreet on One"s Own","The investigation of things" and "Filial piety and fraternalduty, Luo Jinxi also put forward an especial theory which made his thought into a perfect system and reached an extensive and proficient realm.

他融合儒释道的思想精华，用"赤子之心"来表述良知本体，构成其思想的本体论学说；并以此赤子良知为理论基点，追求"万物一体"之仁的境界与"生意活泼，了无滞碍"的洒脱之乐的境界，认为仁之境即是乐之境，乐之境即是仁之境，最终提出追求仁乐合一境界的境界论思想；在工夫理论上，罗近溪强调"放下一切、打破光景"，顺适赤子良知之当下状态，将工夫融释在良知本体中，即工夫即本体，即本体即工夫，表现出一种无工夫之工夫论；在关于慎独、格物、孝悌慈等论题上，近溪也提出了极具理论特色的观点，使其思想形成了一卓然圆熟的体系，达到了一"博通圆融"的境地。

Chapter 4 is the central part of this dissertation, where the bayes bilateral integrated moment is established on the base of Bayes theory, downside risk and upside potential. According to the variation coefficient which is based on the M-V approach, we substitute lower partial moment for the numerator of variation coefficient, and use higher partial moment as the substitute of the denominator, then we got bilateral integrated moment. Subsequently, through Bayes method we can absorb new information, revise the return distribution from transcendental distribution to posterior distribution, so we got bayes bilateral integrated moment.
