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。

Environmental Improvement is the important element in Western China's Development policies It's an impend task to institute effective environment policies The usual environment policies are only to directly resolve the environment problems,which can't eliminate the fundamental origins In order to achieve the aim of administering both its root cause and symptoms,it's necessary for the direct environment policies to be implemented matched with indirect ones It also should pay more attention to reducing th...

环境治理是我国西部大开发战略的重要组成部分，因此制定切实有效的环境政策是当前的迫切任务。通常所说的"环境政策"仅指直接解决环境问题的政策，但若环境问题背后的本质原因不消除，直接环境政策仅能"治标"，无法兼顾经济发展、社会公平等目标，因此需要与间接环境政策配合使用，从而达到"标本兼治"的目的，同时在政策的执行中要注意最大限度地减少对经济行为的干忧，以保证经济、生态的协调发展。

Hybrid schemes in a KEM-DEM structure is regarded as the most natural approach to public key encryption with IND-CCA security and practical efficiency. Traditional KEM is realized by public key scheme, which only provides confidentiality security for session key used by DEM. In 2005, combining the idea of signcryption with the KEM-DEM model hybrid encryption, Alexander proposed a signcryption KEM-DEM model hybrid signcryption primitive.

KEM-DEM结构的混合密码体制是获得IND-CCA安全最实际有效的方法，传统的KEM由公钥加密方案实现，仅提供DEM使用的会话密钥的保密性安全。2005年Alexander等人将签密的概念与KEM-DEM结构的混合密码体制相结合，提出了Signcryption KEM-DEM结构的混合签密。

At present, many effective iterations are all derived from Newton method.

Newton法是求解非线性方程的一个最基本而且十分重要的迭代方法，目前使用的很多有效的迭代法，都是以Newton法为基础，并由它而得到的。

The researcher summarizes three major conclusions as follows. First, 88% of library users suggest the purchase of library materials by utilizing the union catalog, a bibliographic database of ISBNnet, developed by the National Central Library of Taiwan. This method helps increase the reservation of new arrivals on the New Book Display, from the rate of 1.48% to 5.59%. Evidently, the use of the union catalog of ISBNnet as the bibliographic source of library acquisition improves the quality of library collection. Second, with the launch of the Book Recommendation System, it requires only a single staff to deal with the duplication check of book copies; meanwhile, it reduces dramatically the chances of careless purchase of multiple copies of a single work from the rate of 31.23% to 3.53%. Finally, the acquisition model of Inter-Entity Supply Contract shortens the lead time from some time between 55 and 90 days to 36 days in the library acquisition procedures.

It has thus been demonstrated that a tiered approach at all three steps can be helpful to optimize the use of the available resources; if relatively crude tools –designed to provide a "worst case" estimate –do not suggest a toxicologically significant exposure( or a relevant deficit of a particular nutrient) it may not be necessary to use more sophisticated tools.

已经证明，在所有的三个步骤中一种分层的方法能够有效优化可用资源：如果一种相对粗糙的方法――设计用来对最坏的情况进行评估――没有显示有毒理学意义的暴露（或者某种特定营养的不足）――那就不需要再使用更精确的方法。

"After the first week on LipoPuze, I knew it was working. After the first few days, my appetite went away. In fact, I didn't feel I needed to eat anything for 5 hours. I know that is not the best way to lose weight, but I started to see results right away. I started losing weight and within two weeks, I had already lost twice the weight I did with Alli. The great part about LipoPuze is that it made me feel less hungry and it didn't really require me to change the way I eat or the way I exercise, but it automatically does it for me. LipoPuze is a life saver. Thanks for a product that actually helps me lose weight."

&在使用LipoPuze一星期后，我非常兴奋的感觉到了它的效果再之后的几天最有效瘦腿方法里，我的胃口减少了事实上，我不在需要在5小时内不停的吃东西我知道这不是最好的减肥方式，但我开始看到结果了我开始减肥，并在两个星期内，我已经减掉了两倍的重量伟大的部分， LipoPuze它让我感觉不到饿了，它确实改变了我饮食习惯，但它会自动为我减肥 LipoPuze是一种生活程序感谢您的产品，实际上帮助我减肥。&

Some commonly agreed findings of legibility research include: text set in lower case is more legible than text set all in upper case, presumably because lower case letter structures and word shapes are more distinctive, having greater saliency with the presence of extenders (ascenders, descenders and other projecting parts); regular upright type is found to be more legible that italics, contrast, without dazzling brightness, has also been found to be important, with black on yellow/cream being most effective; positive images are easier to read than negative or reversed; the upper portions of letters play a stonger part than the lower portions in the recognition process; legibility is compromised by letterspacing, word spacing and leading that are too tight or too loose.

在易读性研究方面达成的共识包括：小写字母的文本要比全大写字母的文本易读，大致是由于小写字母的结构和词语形状更容易区分，特征更明显——带有延展性的笔画（ascenders上伸笔画， descenders下伸笔画、以及其他的伸展性笔画部件）；标准体字形的易读性要优于斜体；对比很重要——不要用那些耀眼的发光效果；在黄色/奶油色底上使用黑色文字最有效；阳文要比阴文易读；在识别过程中，字母的上部形状要比下部形状发挥更重要的作用；字母间距、词间距和行间距太密集或太松散也会降低易读性。
