Method SummaryModifier and TypeMethodDescription
protected KernelSVMModelCopies a model, replacing its provenance and name with the supplied values.Generates an excuse for an example.
intReturns the number of support vectors used.
(int n)Gets the top
nfeatures associated with this model.Uses the model to predict the output for a single example.

getNumberOfSupportVectorspublic int getNumberOfSupportVectors()Returns the number of support vectors used.
- The number of support vectors.
predictUses the model to predict the output for a single example.
predict does not mutate the example.
IllegalArgumentExceptionif the example has no features or no feature overlap with the model.
getTopFeaturesGets the top
nfeatures associated with this model.
If the model does not produce per output feature lists, it returns a map with a single element with key Model.ALL_OUTPUTS.
If the model cannot describe it's top features then it returns
- Specified by:
n- the number of features to return. If this value is less than 0, all features should be returned for each class, unless the model cannot score it's features.
- a map from string outputs to an ordered list of pairs of feature names and weights associated with that feature in the model
getExcuseGenerates an excuse for an example.
This attempts to explain a classification result. Generating an excuse may be quite an expensive operation.
This excuse either contains per class information or an entry with key Model.ALL_OUTPUTS.
The optional is empty if the model does not provide excuses.
copyCopies a model, replacing its provenance and name with the supplied values.
Used to provide the provenance removal functionality.
