The invention provides a text similarity solution algorithm based on global optimization of keyword quality. The text similarity solution algorithm comprises the following steps: performing word segmentation and stop word removal processing on a text, comprehensively considering the weight, the density, ...
Jaccard相似性系数 引用资料:http://www.ruanyifeng.com/blog/2013/03/cosine_similarity.html(1)使用TF-IDF算法,找出两篇文章的关键词; (2)每篇文章各取出若干个关键词(比如20个),合并成一个集合,计算每篇文章对于这个集合中的词的词频(为了避免文章长度的差异,可以使用相对词频); (3)生成两篇文章各自的词频...
much smaller data size. With EFB, we bundle mutually exclusive features (i.e., they rarely take nonzero values simultaneously), to reduce the number of features. We prove that finding the optimal bundling of exclusive features is NP-hard, but a greedy algorithm can achieve quite good ...
PAN首先是一个轻量级的backbone(如resnet18)得到4个尺度构成的特征金字塔,这些特征经过多个级联的FPEM来增强金字塔特征的表达能力,之后多个特征金字塔经过FFM融合得到融合特征F,模型输出文本区域Text Regions,文本实例内核Kernel,和一个代表像素相似度的Similarity Vector。 后处理 在kernel分割图上查找连通域得到若干文本实例...

图像信息创建者完全在图像信息空间中工作,这个空间还有一个更学术的词:潜在空间(latent space)。此特性使其比以前在像素空间中运行的扩散模型(Diffusion Models)更快。用技术术语来说,这个组件由一个 UNet 神经网络和一个调度算法(scheduling algorithm) 组成。
The BM25 algorithm calculates the matching score between the fields of the candidate sentence by the degree of coverage of the qurey field. The candidate with a higher score has a better matching degree with the query, and it mainly solves the problem of similarity at the lexical level. Deep...
这项技术有大量的使用场景并且已经被用在了很多非常成功的应用当中。无论是为了提高你的业务表现,还是为了自己的知识,文档摘要是所有NLP积极分子所应该熟悉的。 源自:PRATEEK JOSHI(作者)——An Introduction to Text Summarization using the TextRank Algorithm (with Python implementation)...
