全文总字数：1431字1. 研究目的与意义及国内外研究现状本文就函数的极值问题进行了深入的讨论。函数的极值问题是数学研究的重要内容之一，在现实生活中也会遇到求效率最高、利润最大等问题，所以掌握函数的极值问题不仅有利于数学研究，也具有现实意义。国内外研究现状在函数极值问题中，尤其是求解多元函数的极值问题较为复杂。目前国内求解函数极值的方法主要是Lagrange乘数法等，并且在隐函数，微积分函数等都有应用。2. 研究的基本内容本文研究了函数极值的求解方法与实际应用，主要对多元函数的求解方法进行了深入的探讨。3. 实施方案、进度安排及预期效果 第1周至第3周：跟导师确定论文题目，对论文的研究内容做个大致了解。 第4周至第9周：查阅资料，对每个参考文献认真地阅读，进行细致的整理，加入自己的想法，完成论�

1. 研究目的与意义（文献综述包含参考文献） Literature Review Gao Huilian noted that from the dialogue between Hamlet and the main characters in the play and several major actions demonstrated, we can conclude that Hamlet was sober. Firstly, after the dialogue with the ghost of king, Hamlet didn't lose rationality. He asked his friends to keep a secret after the shortest time he restored calmed. Then, he told his friend he would pretend mad in order to revenge. Secondly, he abandoned Ophelia whom he loved deeply. It is hard for him to make this decision. However, it was a correct and helpful way for his revenge. Thirdly, Hamlet keenly knew the purpose was not pure when Rosencrantz and Guildensten visited him. He talked with them used mad and aggressive words to get a real purpose: it was the king and queen let them to test Hamlet. Forth, Hamlet had a chance to kill his uncle Claudius who had not attendants. However he gave up, thought that it is wrong time

1. 研究目的与意义（文献综述包含参考文献）Like I said in the introduction, Hemingway was considered one of the most famed novelist in the 20th century, and his works won him a Pulizter Prize and a Nobel Prize in literature, the two awards only granted to the greatest. Putting these achievements aside, reading Hemingway#8217;s works instills one with lasting inner strength that brings his feet back on the ground, not to mention the pure pleasure while reading his simple but poweful words. Therefore, the elapse of time have#8217;ve quenched people#8217;s desire to explore Hemingway#8217;s masterpieces and his inner world, tons of studies done on the subject with more to come in the future. When people think of Hemingway, certain tags naturally pop into people#8217;s mind like ”Code Hero”, ”Grace under pressure”, ”the lost generation”, and these are among the most explored subjects. Nevertheless, Hemingway#8217;s treasure haven#8217;t been exploited fully

1. 研究目的与意义（文献综述） 1. 目的及意义 （1）深度学习简介 深度学习是近年来计算机科学领域比较热门的研究方向，是机器学习的一个分支。 机器学习指机器能够利用大数据集进行自主学习，而不是通过硬性编码规则，这种学习类型基于现代计算机强大的处理能力，能够在短时间内处理大数据集；并且由于大数据时代的到来，人们收集信息的速度和规模变得很大，从而为机器学习提供了海量数据集。机器学习是人工智能的核心，是使计算机具有智能的根本有效途径。 深度学习的概念源于人工神经网络的研究。神经网络是构成深度学习系统的框架，它由大量彼此相连、概念化的人造神经元组成，分为输入层、隐藏层和输出层。普通神经网络只有一个隐藏层，含有多个隐藏层的人工神经网络便称为深度学习系统。 深度学习分为监督式学习和非

1. 研究目的与意义（文献综述） Researchstatus analysis Adriverless car is a car that senses its surroundings by sensors on the car, andsends out correct driving instructions to the car based on the sensed road andvehicle position, so that the car can safely and reliably travel. However, sometimesthere are many departure situations in the car. In some special cases, the useof natural language description can help the car to avoid accidents morequickly. Therefore, the main research content of this paper is the naturallanguage driving navigation for smart cars. AlbertS. Huang et al. [18] controlled the natural language commands of homemademicro-aircraft. In [17], they gave a method for generating spatial descriptionclauses. In thesame way, in domestic research, many scholars have studied a lot about theanalysis of Chinese natural language directives and the control of thetrajectory of operations. Zhang Xueying [5] proposed: Introducing the solutionto the difficulty of the desc
