A Cluster Identification Method without Using a Threshold of Correlation Coefficient in Hierarchical Cluster Analysis
One of the microarray data analyses using Gene Ontology (GO) [1] is grouping of genes by hierarchical cluster analysis (HCA) followed by extraction of common functions from the grouped genes. When some genes display similar expression changes in response to a situation change, it is thought that those have a similar function or role in a biological process. Therefore, genetic classifications fr...

15 صفحه اولCluster validity analysis using subsampling
I n t r o d u c t i o n The word "clustering" (unsupervised classification) refers to methods of grouping objects based on some similarity measure between them. Clustering algorithms can be classified into four classes, namely Partitional, Hierarchical, Density-based and Grid-based [8]. Each of these classes has subclasses and different corresponding approaches, e.g., conceptual, fuzzy, selforg...
متن کاملEmotion Annotation Using Hierarchical Aligned Cluster Analysis
The correctness of annotation is quite important in supervised learning, especially in electroencephalography(EEG)-based emotion recognition. The conventional EEG annotations for emotion recognition are based on the feedback like questionnaires about emotion elicitation from subjects. However, these methods are subjective and divorced from experiment data, which lead to inaccurate annotations. ...
متن کاملUsing hierarchical cluster analysis in nursing research.
This article is a pedagogical piece on hierarchical cluster analysis, a method for investigating the structure underlying data. Such methods are useful for finding similar groups of cases in data sets when it is not known a priori how many groups are present. The article is laid out asfollows: First, a brief history and overview of the methods is presented; second, an illustrative example with ...
