机器学习:classification (分类),regression (回归), clustering (聚类), dimensionality reduction (降维) 聚类(clustering) 无监督学习的结果。聚类的结果将产生一组集合,集合中的对象与同集合中的对象彼此相似,与其他集合中的对象相异。 没有标准参考的学生给书本分的类别,表示自己认为这些书可能是同一类别的(具体什...
聚类(Clustering) Group similar data points together. 异常检测(Anomaly Detection) Find unusual data points. 降维(Dimensionality reduction) Compress data using fewer numbers. 4. 线性回归(Linear Regression) 线性回归是回归的一个例子,它搭建一个线性模型,从而预测回归问题。 这里我们可以回顾一下概念 回归模型(...
Two popular methodologies of CI include neural networks and fuzzy systems. Lately, a unification was proposed in CI, at a "data level", based on lattice theory (Kaburlasos, 2006). More specifically, it was shown...doi:10.1007/978-3-540-34170-3_7Vassilis G. Kaburlasos...

在上一篇文章中在下浅显地总结了一些流行的聚类(clustering)的算法,在这篇以及下篇文章我们来聊一聊一些流行的分类(classification)算法。分类算法跟属于unsupervised learning的聚类算法不同,属于supervised learning。用人话翻译一下,分类算法尝试着给数据贴上标签,而且这些标签都是可以观测到的。比如把人分成男人跟女人,...
A method and a system which apply a regression clustering algorithm and a classification algorithm on the dataset are provided. In particular, a method and a system are provided which generate a plurality of different functions correlating datapoints of a dataset and determine directives by which to...
【解释】Clustering groups data into groups or clusters based on how similar each item (such as a hospital patient or shopping customer) are to each other. Practice quiz: Regression 第1 个问题:For linear regression, the model is f_{w,b}(x)=wx+b. Which of the following are the inputs...

Clustering accuracy is evaluated using purity (see materials and methods). The Fuzzy k-Means algorithm reaches a purity value of 0.934 (see Fig. 2a, b), outperforming the standard k-Means (purity value = 0.887) and GMM22 (purity value = 0.886). A posterior analysis of the ...
