transformToPrediction

public Prediction<Label> transformToPrediction(org.tensorflow.Tensor<?> tensor,
 ImmutableOutputInfo<Label> outputIDInfo,
 int numValidFeatures,
 Example<Label> example)

Description copied from interface: OutputTransformer

Converts a Tensor into a Prediction.

Specified by:

transformToPrediction in interface OutputTransformer<Label>

Parameters:

tensor - The tensor to convert.

outputIDInfo - The output info to use to identify the outputs.

numValidFeatures - The number of valid features used by the prediction.

example - The example to insert into the prediction.

 ImmutableOutputInfo<Label> outputIDInfo)

Description copied from interface: OutputTransformer

Converts a Tensor into the specified output type.

Specified by:

transformToOutput in interface OutputTransformer<Label>

Parameters:

tensor - The tensor to convert.

outputIDInfo - The output info to use to identify the outputs.

Returns:

A output.

transformToBatchPrediction

public List<Prediction<Label>> transformToBatchPrediction(org.tensorflow.Tensor<?> tensor,
 ImmutableOutputInfo<Label> outputIDInfo,
 int[] numValidFeatures,
 List<Example<Label>> examples)

Description copied from interface: OutputTransformer

Converts a Tensor containing multiple outputs into a list of Predictions.

Specified by:

transformToBatchPrediction in interface OutputTransformer<Label>

Parameters:

transformToBatchOutput

public List<Label> transformToBatchOutput(org.tensorflow.Tensor<?> tensor,
 ImmutableOutputInfo<Label> outputIDInfo)

Description copied from interface: OutputTransformer

Converts a Tensor containing multiple outputs into a list of Outputs.

Specified by:

transformToBatchOutput in interface OutputTransformer<Label>

Parameters:

tensor - The tensor to convert.

transform

public org.tensorflow.Tensor<?> transform(Label example,
 ImmutableOutputInfo<Label> outputIDInfo)

Description copied from interface: OutputTransformer

Converts an Output into a Tensor representing it's output.

Specified by:

transform in interface OutputTransformer<Label>

Parameters:

example - The output to convert.

outputIDInfo - The output info to use to identify the outputs.

Returns:

A Tensor representing this output.

transform

public org.tensorflow.Tensor<?> transform(List<Example<Label>> examples,
 ImmutableOutputInfo<Label> outputIDInfo)

Description copied from interface: OutputTransformer

Converts a list of Example into a Tensor representing all the outputs in the list. It accepts a list of Example rather than a list of Output for efficiency reasons.

Returns:

A Tensor representing all the supplied Outputs.

generatesProbabilities

public boolean generatesProbabilities()

Description copied from interface: OutputTransformer

Does this OutputTransformer generate probabilities.

Specified by:

generatesProbabilities in interface OutputTransformer<Label>

Returns:

True if it produces a probability distribution in the Prediction.

toString

public String toString()

Overrides:

toString in class Object

getProvenance

public com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance getProvenance()

Specified by:

getProvenance in interface com.oracle.labs.mlrg.olcut.provenance.Provenancable<com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance>
