This quantity presents ways and recommendations to hard difficulties happening on the interface of analysis fields resembling information research, desktop technology, operations learn, and statistics. It contains theoretically orientated contributions in addition to papers from a number of software parts, the place wisdom from varied study instructions is required to discover an sufficient research and interpretation of the saw info that fit optimally the underlying sensible occasions. Beside conventional category learn, the booklet focuses additionally on present pursuits in fields akin to the research of community information, graphs, and social relationships in addition to on statistical musicology.

The increasing size of data sets poses challenges to their statistical treatment. Cluster analysis methods such as the proposed accelerated K-means can help to summarize large data sets, and thus to reduce their size and complexity. A general principle of dealing with large data sets is clustering based on subsamples. It dates back to Kaufman and Rousseeuw (1986) (see for a modified version in Kaufman and Rousseeuw 1990). The remaining observations (not belonging to the sub-sample) are classified subsequently into the clusters.

We must analyze huge and complex data sets. Conventional methods for data analysis cannot be applied to these data sets directly. In such a case, an approach M. Mizuta ( ) H. jp W. Gaul et al. 1007/978-3-642-24466-7 3, © Springer-Verlag Berlin Heidelberg 2012 23 24 M. Mizuta and H. Minami is to classify the observations into distinct groups and to analyze the groups. But, the groups are not ordinary observations but sets, distributions, intervals etc. In the 1980s, Diday proposed SDA (Symbolic Data Analysis) to deal with these kinds of data (Diday and Bock 1987).
