Summary
In preparation for the application of data mining algorithms, most datasets need
some modification. These modifications include:
projection - attribute selection
restriction - filtering of observations
sub-population extraction
aggregation - combining of observations
elimination of missing values
derivation of new columns
merging of datasets
detection and elimination of outliers.
VisMiner supports all of these operations. Where suitable, some are sup-
ported within the parallel plot, correlation matrix, and location plot viewers.
Other modification operations are implemented directly in the Control Center.
