Visualisation for Data Mining

TL;DRAbstract

Modern computing power makes possible analysis of larger and larger data sets and many new methods have been suggested under the broad heading of Data Mining. Visualisation of data, of model-fitting, and of results plays an important part, but large data sets are different and new methods of display are needed for dealing with them. This paper reviews the standard problems in displaying large numbers of cases and variables, both continuous and categorical, and emphasises the need for improving current software. Much could be achieved by adding interactive tools like querying, linking and sorting to standard displays to provide greater flexibility and to facilitate a more exploratory approach. 1 What is Data Mining? Large data sets are more and more common. Every organisation is able to collect and store vast quantities of information. Supermarkets have sales figures for individual items and for customers. Phone companies have details of every phone call made. Weather compute...
