学习

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。

My name is XX,24 years old,Koreaner,and graduated from XX major on july this year.i have dad ,mom,and sister in my family.father is a worker in a airport,while mother is a teacher.i grew up at such traditional family,so parents were strict with me,they tought me much.until graduation from high school,I was able to enterYanbian University without parents' care.instead of feeling reluctant to part with parents,I was imvolved in new life rapidly.because of my lively personality and easy-going,teachers and classmates spoke highly of me.at other times,I loved reading and searching information in the internet.morover,I reinforced own Korean,english and computer competency continuously,took advantage of two years to study korean in the opportunity class,and then met many foreign friends to proceed mutual learning as partners.over my four-studing out of home,I cultivated strong characteristic,which made me overcome many difficulties from studying nad living.i majored in education technology ,the professional subjects contain three aspects about hardware and software on computer,education and use of multimedia,for example,OFFICE software,IMAGE-PROCE ING software,NLE software and various computer language,data organization,digit circuit,education,educational psychology,distance learning etc.i valuing practice often do come part-time jobs to accumulate some social practice experiences by making use of outside school hours ,except for the basic curriculums in the school.in my leasure time,I often go sporting,such as mountaineering,swimming,riding bicycle and so on,as well as paricipation some activities organized by sc

我叫XX，今年24岁，朝鲜族，今年7月毕业于XX专业。家庭成员有爸爸、妈妈和姐姐，父亲是一名飞机厂工人，母亲是一名人民教师，从小在这样传统的家庭中成长，父母对我的管教也很严格，教会了我许多做人的道理。直到高中毕业，离开父母呵护的臂膀来到了延边大学，没有对家的恋恋不舍，而是很快的融入到了新的生活中，由于我的性格活泼开朗并且随和，老师和同学们对我的评价也都非常好，平时我喜欢看书和上网浏览信息，另外不断加强自身的韩国语、英语和计算机能力，利用两年时间在补习班学习了韩国语，并认识了许多外国朋友结成partner互补学习，在外求学的四年中，我养成了坚强的性格，使我克服了许多学习上和生活中的一些困难。我的专业是教育技术学，专业课程包括计算机的硬件及软件、教育学和多媒体的使用三大方面。OFFICE软件、图象处理软件、非编软件以及各种计算机语言数据结构，数字电路，教育学、教育心理学、远程教育等。注重实践的我除了学校的基本课程外，经常利用课余时间做一些兼职以积累一定的社会实践经验，平时还喜欢做一些运动，例如登山、游泳、骑自行车等，并经常参加学校里组织的一些活动。开朗乐观是我对待生活的态度，吃苦耐劳是我对待工作的原则。

Students become self-contempt as the mistakes caused by themselves. so, in mathematics teaching, if the teachers can dissimulate skillfully, they can be able to take care of students' fragile feelings, and give students strength to overcome difficulties and setbacks so as to enter the virtuous cycle track, gradually "turning around" in learning.

学困生由于学习上的失误而引起自卑，在数学课堂教学中，教师若能巧妙地装装糊涂，就能呵护他那脆弱的情感，给他注入发奋学习的"强心剂"，增强战胜困难与挫折的信心，使他在数学的学习上进入良性循环的轨道，渐渐"脱困"。
