深度学习在NLP中的应用——TextCNN 1. 概述 卷积神经网络(Convolutional Neural Networks,CNN)的提出使得深度学习在计算机视觉领域得到了飞速的发展,大量基于CNN的算法模型被提出,同时深度学习算法在多个视觉领域实现了突破。最初在文本领域,主要使用的深度学习模型是RNN,LSTM等,既然CNN在图像领域得到广泛的应用,能否将CNN...
比如像匹配单词the却没有匹配The。 基本上在NLP分析过程(甚至是所有机器学习问题)都是在处理这两类错误。减少一类错误(假阳性)意味着提高模型精度;减少二类错误(假阴性)意味着增加召回率。 总结: 正则表达式很强大,通配操作很方便,一般也是文本处理的第一步。在许多困难的任务中用到的机器学习分类器也会使用正则表达...
文本预处理对于NLP任务至关重要,因为它可以: 去除噪声,提高数据质量。 统一文本格式,消除不同表示方式带来的差异。 增强模型的泛化能力,使其能够处理各种形式的文本输入。 文本预处理的常见步骤 1. 去除特殊字符和标点符号 去除文本中的特殊字符和标点符号,以减少无关信息的干扰。 2. 转换为小写 将所有文本转换为小...

Let's take a look at a few examples. A clothing brand is very likely to closely monitor the customer reviews they are getting on a new product line in the market. If the reviews are in thousands, automation becomes a necessity, and text processing techniques come into play. On the other...
Processing Patterns in Text - an Alternative Approach to NLP.Rogers, PaulLefley, Martin
文本数据挖掘是利用某些方法比如自然语言处理(Natural language processing (NLP))技术把一堆没有结构的数据而处理成有结构的数据的一种人工智能技术,而处理后的这些有结构的数据可以作为机器学习和深度学习模型的输入,也可以直接分析这些数据产生想要的结果。

Different Fine-Tuning Techniques Train the entire architecture– We can further train the entire pre-trained model on our dataset and feed the output to a softmax layer. In this case, the error is back-propagated through the entire architecture and the pre-trained weights of the model a...
在NLP中,Jia和Liang(2017)将语法正确但语义无关的段落插入到故事中,以愚弄神经阅读理解模型。Singh等人(2018)发现,当使用简单的原问题释义时,用于回答问题的神经模型的性能显著下降。 不像以前的NLP攻击场景,视觉攻击,即(1)它们不需要任何超出字符级别的语言知识,使攻击直接适用于不同的语言、领域和任务。2)据称,...
