DimensionReducerFunction
represents a function generated by DimensionReduction that projects data onto a lower-dimensional approximating manifold.
Details and Options
- DimensionReducerFunction works like Function.
- DimensionReducerFunction[…][example] projects the single example example onto the approximating manifold.
- DimensionReducerFunction[…][{example1,example2,…}] projects all the examplei.
- DimensionReducerFunction[…][data,prop] gives the specified property of the dimension reduction associated with data.
- Possible properties include:
-
"ReducedVectors" reduction of the vectors given "OriginalData" deduced original examples given reduced vectors "ReconstructedData" reconstruction by reduction and inversion "ImputedData" missing values replaced by imputed ones - DimensionReduction[DimensionReducerFunction[…],FeatureExtractorfe] can be used to prepend the FeatureExtractorFunction[…] fe to the existing feature extractor.
