Data filtering, in particular for normalization and projection.
Interface Summary Interface Description ObjectFilterObject filters as part of the input step. StreamFilterStreaming filters are often more efficient (less memory use) as they do not keep a reference to earlier data.
Class Summary Class Description AbstractConversionFilter<I,O>Abstract base class for simple conversion filters such as normalizations and projections. AbstractStreamConversionFilter<I,O>Abstract base class for simple conversion filters such as normalizations and projections. AbstractStreamFilterAbstract base class for streaming filters. AbstractVectorConversionFilter<I,O extends NumberVector>Abstract class for filters that produce number vectors. AbstractVectorStreamConversionFilter<I,O extends NumberVector>Abstract base class for streaming filters that produce vectors. FilterUtilUtilities for implementing filters. FixedDBIDsFilterThis filter assigns static DBIDs, based on the sequence the objects appear in the bundle by adding a column of DBID type to the bundle. FixedDBIDsFilter.ParParameterization class. NoOpFilterDummy filter that doesn't do any filtering.
