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。

These "problem properties" from the causes can be divided into seven categories: The first is caused by disordered development; second is not strictly project approval, business-to-project development funds are not implemented; third is absconding money led to real estate developers failed to materialize; four the project to rely on bank loans, the state tightened money supply, no follow-up support for the construction funds for construction; five real estate policy is due to gradually improve over the past administrative allocation of land are required to pay a large number of land transfer and value-added tax to pay the gap too big , developers can not afford to pay; Sixth, the lack of project feasibility study, sales difficult construction projects shall not be able to implement; Seven developers for other economic cases sealed by the court project.

这些&问题性质&的原因可分为七类：第一是所造成的无序发展；二是不严格项目审批，企业对项目的开发资金不落实；三是潜逃钱导致房地产开发商未能实现；四个项目依赖于银行贷款，国家收紧货币供应量，没有后续支持建设建设资金；五年房地产政策是逐步改善，在过去的行政分配土地都必须支付了大量的土地转让和增值税支付的差距太大，开发商无力支付；第六，缺乏项目可行性研究，销售困难的建设项目将无法实施；七开发其他经济案件由法院密封项目。

The software called Protel99SE for circuited signed is used to develop the hardware of the controller. The hardware includes the power supply Printed Circuit Board, the signal modulation board, the interface board of human %26amp; machine,and the main control board which is the core of this controller.

锅炉的特点，研制开发了基于MCS-51单片机的小型家用燃气锅炉智能控制器，旨在改变城镇居民使用燃煤锅炉集中采暖时所遇到的室内温度不易控制、无法实现智能控制等的不便，减少因燃煤而产生的大气污染，提高天然气的使用率，改进家庭采暖的控制方式，提高采暖的经济性，改善人们的生活设施。

The difficulty in controlling the different parameters (metabolic, vascular, infectious, and foot off-loading) involved in the evolution of the diabetic foot and the lack of prospective randomized studies on the effect of HBO on this pathophysiological condition make it difficult to recognize HBO as an incontrovertible treatment.

法国斯特拉斯堡大学医院的Laurence Kessler博士表示，之前已经有研究提议HBO可以作为糖尿病患者足部溃疡的辅助治疗，因为它可以改善复杂的痊愈过程，控制糖尿病足部溃疡发展之不同参数（代谢、血管、感染和脚的负重）的困难点及缺乏HBO效果的预期性随机化研究，使得研究人员无法证实HBO是一种有效的治疗方式。

Since the founding of the nation, our country's automobile industry has been throughout grows in the swaddling clothes, freely the 50s "the breakthrough", the 80s "the improvement", the early 90s "the government" and recent years's enhancement, has enabled the nationality automobile industry to have made great strides, but under the many year planned economy systems toddles the automobile enterprise not yet completes the accumulation of capital, but is also unable with the overseas automobile giant to contend with.

With a supporter in Mr Charest and an admirer in Mr Dumont, Mr Harper may be encouraged to call an election himself.

由于在沙雷那边有个支持者，杜蒙那边有个崇拜者，鼓励哈珀为自己举行一次选举。
