This paper introduces concepts and algorithms of feature selection, surveys existing feature selection algorithms for classification and clustering, groups and compares different algorithms with a categorizing framework based on search strategies, evaluation criteria, and data mining tasks, reveals unattempted...
In the literature, several clustering and classification algorithms have been proposed which work on network data, but they are usually tailored for homogeneous networks, they make strong assumptions on the network structure (e.g. bi-typed networks or star-structured networks), or they assume that...
The other major difference is since classification techniques have labels, there is a need for training and test datasets to verify the model. In clustering, there are no labels so there is no need for training and test datasets. Popular examples of classification algorithms are: ...
algorithms with a focus on clustering and classification because of their ubiquitous usage. It identifies mining constraints, proposes a general model for data stream mining, and depicts the relationship between traditional data mining and data stream mining. Furthermore, it analyzes the advantages as ...
Algorithms in this family include the neighboring component analysis [15], large margin nearest neighbor classification [16], large margin component analysis [17], class collapse [18], and other extension work [19], [20]. The success in a variety of problems shows that the learned distance ...
文本分类与聚类(text categorization and clustering) 1. 概述 广义的分类(classification或者categorization)有两种含义:一种含义是有领导的学习(supervised learning)过程,另一种是无领导的学习(unsupervised learning)过程。通常前者称为分类,后者称为聚类(clustering),后文中提到的分类都是指有指点的学习过程。

Data-driven classification of disease is a recent idea, made possible by access to large population studies, such as UK Biobank5. Examples include using molecular or imaging data to identify and classify subtypes of disease such as metabolic syndrome6, amyotrophic lateral sclerosis (ALS)7, cancer...
