Symbolic Hierarchical Clustering for Pain Vector
We propose a hierarchical clustering in the framework of Symbolic Data Analysis(SDA). SDA was proposed by Diday at the end of the 1980s and is a new approach for analysing huge and complex data. In SDA, an observation is described by not only numerical values but also “higher-level units”; sets, intervals, distributions, etc. Most SDA works have dealt with only intervals as the descriptions. We already proposed “pain distribution” as new type data in SDA. In this paper, we define new “pain vector” as new type data in SDA and propose a hierarchical clustering for this new type data.
