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。

During 1980 to 2002, the whole patch's quantity increases and has the phenomenon of crumble. In addition, the distribution of each patch becomes more disperse gradually, and the enchase decreases. During 2002 to 2006, after the creek engineering project has been put in place for several years, the whole landscape structure starts to become in ordered. Proven by the bird research data, higher sample are mostly scatter along the river side. Therefore, the creek engineer is able to stabilize our environment, and the big patch is increasing because of the plan of patch, as a result, the variety of birds in the testing area increases by a significant number.
於1980 ~ 2002年间，在人为大力开发加上天然风灾肆虐下，整体块区之数量渐增且形状有呈现破碎化之现象，而各类别块区之分布逐渐分散，且镶嵌度亦有下降之情形。2002 ~ 2006年，经逐年之野溪工程整治，整体景观结构有朝向规整化的情形，且以鸟类调查资料验证，丰度较高之样点大多沿著溪流分布，故可得知，野溪工程之施作对环境有稳定之功能，且因块区之规整使大块区数量增加，亦使研究试区之鸟类生态丰富度增加。

Objective To explore livin, MTA1 and the caspase3 protein expression, their correlation and clinical pathology in colon cancer Methods The expressions of livin, MTA1 and caspase3 protein in 88 cases of colon cancer were detected by immunohistochemistry stainingResults Livin, caspase3 protein and MTA1 positive expression rates in colon cancer tissues were more than those in tissues beside the cancer Furthermore there were obvious relevance between livin protein, MTA1 positive expression rate and degree of histodifferentiation and lymph node metabasis and between caspase3 protein positive expression rate and degree of histodifferentiation of colon cancer Caspase3 protein expression had prominent inverse correlation with the livin expressionConclusions ①Over expression of livin having inhibtion on colon cancer is one of important factors of colon carcinogenesis ②Caspase3 protein expression in colon cancer tissues is inhibited to less and has prominent inverse correlation with livin expression Accordingly, suppressing caspase3 protein activity is one of channels, by which livin promotes colon carcinogenesis ③MTA1 plays the important role in histodifferentiation degree and lymph node metastasis of colon cancer
采用免疫组织化学染色方法检测88例结肠癌组织中Livin，Caspase3 及MTA1的表达情况。结果（1）结肠癌组织中Livin的阳性表达率显著高于癌旁组织，且Livin的表达与结肠癌的组织分化程度及淋巴结转移程度显著相关。（2）结肠癌组织中Caspase3蛋白的阳性表达率显著高于癌旁组织，且Caspase3蛋白的表达与结肠癌的组织分化程度显著相关。（3）结肠癌组织中MTA1的阳性表达率显著高于癌旁组织，且MTA1的表达与结肠癌的组织分化程度及淋巴结转移程度显著相关。（4）Caspase3蛋白的表达又与Livin的表达呈显著负相关。结论（1）Livin在结肠癌组织中过表达，它可能是促进结肠癌发生的重要因素之一。（2）Caspase3蛋白在结肠癌组织中表达被抑制而降低，且与Livin的表达呈负相关。因此，抑制Caspase3蛋白的活性是Livin促进结肠癌发生的途径之一。（3）MTA1对结肠癌的组织分化及淋巴转移发挥重要作用。
