Class OCILabelConverter

java.lang.Object

org.tribuo.interop.oci.OCILabelConverter

All Implemented Interfaces:

com.oracle.labs.mlrg.olcut.config.Configurable, com.oracle.labs.mlrg.olcut.provenance.Provenancable<com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance>, Serializable, OCIOutputConverter<Label>

public final class OCILabelConverter
extends Object
implements OCIOutputConverter<Label>

A converter for DenseMatrix and DenseVector into Label Predictions.

If the input has length 1 it is assumed to be a single label value, otherwise it must have length = outputIDInfo.size().

Method Details

convertOutput

public Prediction<Label> convertOutput(DenseVector scores,
 int numValidFeature,
 Example<Label> example,
 ImmutableOutputInfo<Label> outputIDInfo)

Description copied from interface: OCIOutputConverter

Converts a dense vector into a single prediction of the appropriate type.

Specified by:

convertOutput in interface OCIOutputConverter<Label>

Parameters:

scores - The score vector.

numValidFeature - The number of valid features (stored in the prediction).

example - The example (stored in the prediction).

outputIDInfo - The output information.

Returns:

A prediction representing the value of this score vector.

convertOutput

Specified by:

convertOutput in interface OCIOutputConverter<Label>

Parameters:

scores - The score matrix.

numValidFeatures - The number of valid features in each example (stored in the prediction).

examples - The examples (stored in the prediction).

outputIDInfo - The output information.

Returns:

A list of predictions representing the value of this score matrix.

generatesProbabilities
