人工智能 •Artificial Intelligence【关键词】深度学习 自然语言1 简介随着当今国际间交流更加频繁和深入,作为世界上应用最广泛的语言,英语已经渗入到生活的方方面面,学习英语对于绝大部分非英语母语的学生们来说都是必要的。
而这其中,在英语学习以及国际性英语考试(如IELTS, TOEFL)中,写作均占了很大的比例,达到考基于深度学习改善英文写作文/蔡畅之试总成绩的25% - 35%。
同时,写作和阅读是息息相关的,在提高学生写作水平的同时,也会相应地提高他们的阅读水平。
但当今传统的写作批改和提高反馈大多是书面形式,一方面,由于繁重的教学任务,很多英语教师对学生的反馈十分有限,另一方面,学生对老师给予的写作反馈也马虎对待,敷衍了事。
所以开发帮助提高写作水平的软件就显得十分必要。
对于非英语母语学生英语写作的评改,在中国比较流行的为批改网(),它是基于语料库和云计算的英语作文自动批改的在线服务。
但该网站对于使用者输入的英文语句目前仅限于指出作者的一些”语法错误”或“词汇,时态错误”的问题,并不能判断写作水平的高低,以及给出修改句子的合理化建议,使表达更加地道,接近于母语表达者的习惯。
本设计基于深度学习(Deep Learning),通过构建递归神经网络(Recurrent Neural Network)中的编码器(Encoder)和译码器(Decoder),以及序列到序列(Sequence-to-Sequence)模型,使用Python语言和PyTorch 工具,训练大量的英语母语者的写作文本(txt),以及英语学习者的写作文本,使机器可以判断出英语学习者的写作习惯以及英语母语表达者的习惯。
这样机器可以了解写作者的常用错误表达习惯,并且给出相应的修改建议。
使用者通过输入自己写作的的英文语句,同时收到更加地道的表达方式输出反馈,通过这种方法,提高使用者的英文写作水平。
2 背景2.1 语言学背景早在上世纪60年代末,Harris, D. P.就曾提到过:书面练习的要点,灵活性,表达方式主要体现在词汇量的积累,以及阅读量的大小,以及实践练习的情况,是从依赖到独立的过程。
表1句子P(futher|句子)P(futher|句子)I need to run farther than Mary0.3350.665Without further issue, we must take action0.9980.002If you complain further, I’m going to shoot you out of the airlock0.9210.079的应用于高校计算机实验室的建设,能够有效促进高校计算机实验室建设的变革。
3.2 云计算技术在高校计算机建设变革中的应用(1)利用云计算技术可以在高校的计算机系统中建立起一个物理资源层,物理资源层主要是指切实的物理计算机,它可以具体指的是一个具体的服务器或是工作站等,通过实际的硬件设备之间的网络连接建设起一个物理资源层,在这个物理资源层中的所有的计算机资源以及相关的理论资源都可以共享并且不受限制,并且在网络中的任一地方都可以调取,通过将学学校内部的计算机资源在局域网中连接起来,就构成了系统中的物理资源层,从而使计算机系统的处理能力更强,网上的知识信息资源的种类也更加的丰富,也可以实现大范围的资源共享。
(2)利用云计算技术可以在校内的计算机控制系统中构建起云管理层,在这个云管理层中可以为整个云计算中心提供安全、稳定的运行条件,有效的减少计算机系统在运行的过程中出现停滞或是系统紊乱的情况,利用云计算技术构建起来的云管理层主要包括云安全管理、云数据管理以及用户管理、云资源管理等,这些内容有着各自的功能,并且均能促进计算机系统的优化,确保电脑信息以及用户信息的安全,例如资源管理主要是对虚拟资源层的各种虚拟资源进行负责,可以对资源的状态进行监控,实现资源的优化配置,加强电脑的安全管理,比如设置电脑的访问权限等,最重要的是通过云计算技术可以实现对数据的加密性管理。
针对机房的云计算可以对学生实现权限管控,对学生终端的操作系统复原保护,病毒源切断,降低软硬件故障率,大大减少了管理人员对软硬件升级维修工作压力。
更直观的是机房空间环境得到改观。
4 结语总而言之,在信息化时代下,高校的计算机实验室建设的改革已经成为高校计算机教育发展的最终归属,高校必须要正视在计算机建设方面存在的问题,必须按照国家标准规范计算机实验室建设,利用先进的信息科学技术实现计算机实验室建设的改革。

写作对于语言的综合应用能力检测起着至关重要的作用,既可以体现学生的词汇积累量,也可以体现学生的表达能力。
2.2 自然语言处理自然语言处理(NLP )是计算机科学的一个领域,它是人工智能的一个分支,帮助计算机理解人类语言的写作和口语,特别是如何对计算机进行编程以成功处理大量自然语言数据。
自然语言处理中的应用方向通常涉及语音识别,自然语言理解和自然语言生成。
2.3 朴素贝叶斯(Na ïve Bayes)自然语言处理中,朴素贝叶斯被广泛应用在句子分类、词汇频率检测等问题中。
该方法基于贝叶斯原理(Bayes Theorem ),特征条件相互独立的模型。
根据贝叶斯原理,对一个分类问题,给定样本特征x ,样本属于类别y的概率是:在这里,x 是一个特征向量,将设x 维度为M 。
因为假设特征条件独立,根据全概率公式展开,上述公式可以表达为:如上式所示,只要分别估计出x^i 在每一类的条件概率就可以。
通过该式我们可以得出对应的每一类上的,条件独立的特征对应的条件概率。
朴素贝叶斯在自然语言处理中常被用于改正语法错误之中。
以现代出版书籍作为语料库,使用“'further vs farther ”方法,围绕关键词的词标记,对朴素贝叶斯公式进行处理,使每个单词在主关键字的左右1-2位[16]。
借此发现,单词"further" 和 “farther ” 的使用均达到了较高的正确率,表1举例说明朴素贝叶斯概率结果。
如表1所示,朴素贝叶斯模型可以很好地纠正这些句子的语法。
Tory 等人以此统计学模型遍历关键词列表来完善功能更加齐全的语法检查器,找出不易察觉的语法错误,由此来改善语法。
2.4 RNN与传统的朴素贝叶斯模型及其它基于统计学的模型不同,递归神经网络(RNN )是一类人工神经网络,单元之间的连接形成沿着序列的有向图。
这使得它可以表现时间序列的动态时间行为。
与前馈神经网络不同,RNN 可以使用其内部状态(内存)来处理输入序列。
这使它们适用于诸如未分割,连接手写识别[4]或语音识别等任务。
递归神经网络有时不加区分地用于两类具有类似结构的网络,其中一个是有限冲动,另一个是无限冲动。
这两类网络都表现出时间动态行为。
有限脉冲递归网络是一个有向无环图,可以展开并用严格前馈神经网络代替,而无限脉冲递归网络是一个不能展开的有向循环图。
有限脉冲和无限脉冲周期性网络都可以有额外的存储状态,并且存储可以由神经网络直接控制。
如果存储时间延迟或有反馈循环,则存储也可以由另一个网络或图形取代。
这种受控状态被称为门控状态或门控记忆,并且是长期短期记忆(LSTM )和门控循环单元(GRU )的一部分。
2.5 序列到序列模型(Sequence to sequence model)递归神经网络(RNN )有许多的变形,例如基本的序列到序列模型由两个递归神经网络组成:处理输入的编码器和生成输出的解码器,图1描述了这个基本架构:图1中的每个框表示RNN 的小区(cell ),最常见的是GRU 小区或LSTM 小区。
编码器和解码器可以共享权重,或者更加常见的是,它们使用不同的参数集。
该模型的工作原理是通过多层LSTM 将输入序列映射为固定维度的向量,然后使用另一个深度LSTM 从向量中解码目标序列。
序列到序列模型有很多应用,比如说谷歌公司将其应用在改正外语语法方面。
除此之外,序列到序列模型还有许多其他应用,例如机器翻译。
2.6 机器翻译(Machine Translation)机器翻译是计算语言学的一个子领域,它主要研究使用软件翻译文本或从一种语言到另一种语言的转化。
机器翻译旨在将源语言句子找到最有可能的目标语言句子,这些句子匹配到最相似的意思。
实质上,机器翻译是序列到序列模型的预测任务。
神经机器翻译(NMT )如今常被作为一种先进的方法,其潜力可以解决传统机器翻译系统的许多缺点。
NMT 的优势在于它能够以端到端的方式直接学习从输入文本到输出文本的相关映射。
其架构通常由两个递归神经网络(RNN )组成,一个用于消耗输入文本序列,另一个用于生成翻译的输出文本。
NMT 通常伴随着注意机制,这有助于它有效处理长输入序列。
Google 公司对NMT 技术进行了相关改进,形成了GNMT 系统,它由一个深度的LSTM 网络组成,该系统有效改正了原来NMT对罕见词语准确性差,反应慢的缺点。
图1:基本的序列到序列模型,此模型读取输入句子“a1a2a3”并输出句子“A1A2A3A4”图2:英文写作具体的提升方法人工智能 •Artificial Intelligence 3 方法3.1 提升过程如图2所示,完成上部分流程,即得到数据并完成清理之后,我们将所整理好的的优质语料库和较差语料库放入写好的序列到序列模型中,进行训练,可以得到一定量的数据来进行测试。
