The change detection process performed by unsupervised techniques is usually divided into three main sequential steps : pre - processing , image comparison ( to generate difference image ) and analysis of the difference image 非监督图象变化检测过程通常可以分为预处理、图象比较(得到差异图象)和差异图象分析三个步骤。
Both theories are combined to classify the documents by unsupervised learning and discuss the method in which new rules , applied to new unclassified documents , can be formed after classifying the training documents 本文利用文档聚类和粗糙集约简相结合的方法，对训练文档进行分类，形成规则后对新加入的未分类文档进行归类。
The experiment introduces that the concept of equivalent pseudowords and unsupervised wsd technology based on equivalent pseudowords provide a new thought and method for exploring the new technology of wsd 实验表明等价伪词的概念以及建立在等价伪词基础上的无指导词义消歧技术为探索词义消歧的新技术提供了一个新的思路和方法。
In the end , multispectral image fusion algorithms based on principal component analysis and clustering algorithms are introduced . multispectral image fusion based on unsupervised classification is realized 最后，还介绍了基于主成分分析( pca )的多光谱图象融合方法以及非监督分类的方法，并实现了基于非监督分类的多光谱图象融合算法。
As part of the censure , gross was banned from performing unsupervised autopsies and ordered to perform 20 autopsies under the supervision of a state - designated forensic pathologist as well as to observe 20 others 作为禁令的一部分，格若斯被禁进行无人监管的验尸工作并被令在州府指定的验尸病理学家监管下进行20次验尸并观察另20个验尸案例。
Self - organizing maps are a kind of unsupervised neural network , which project high - dimensional data to lower dimensions and , at the meantime , visually uncover the similarity among the original high - dimensional data 摘要自组映射图是一种非监督式学习类神经网路，可以将高维度资料投射到低维度空间，并以视觉化方式呈现，反映高维度资料之间的相似度。
The early studies of wsd were to rely mainly on based knowledge and supervised machine learning methods , with the improvement of computing and storage technology , unsupervised methods have been paid more and more regard 早期的词义消歧研究以基于知识的和有指导的机器学习方法为主,随着计算技术和存储技术的改进和提高,无指导方法受到的重视程度越来越高。
