Class QuartileResponseProcessor<T extends Output<T>>

java.lang.Object
org.tribuo.data.columnar.processors.response.QuartileResponseProcessor<T>
All Implemented Interfaces:
com.oracle.labs.mlrg.olcut.config.Configurable, com.oracle.labs.mlrg.olcut.provenance.Provenancable<com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance>, ResponseProcessor<T>
public class QuartileResponseProcessor<T extends Output<T>> extends Object implements ResponseProcessor<T>
Processes the response into quartiles and emits them as classification outputs.

The emitted outputs for each field are of the form: {<fieldName>:first, <fieldName>:second, <fieldName>:third, <fieldName>:fourth} .

  • Constructor Details

    • QuartileResponseProcessor

      public QuartileResponseProcessor(String name, String fieldName, Quartile quartile, OutputFactory<T> outputFactory)
      Constructs a response processor which emits 4 distinct bins for the output factory to process.

      This works best with classification outputs as the discrete binning is tricky to do in other output types.

      Parameters:
      name - The output string to emit.
      fieldName - The field to read.
      quartile - The quartile range to use.
      outputFactory - The output factory to use.

    • QuartileResponseProcessor

      public QuartileResponseProcessor(List<String> fieldNames, List<Quartile> quartiles, OutputFactory<T> outputFactory)
      Constructs a response processor which emits 4 distinct bins for the output factory to process.

      This works best with classification outputs as the discrete binning is tricky to do in other output types.

      Parameters:
      fieldNames - The field to read.
      quartiles - The quartile range to use.
      outputFactory - The output factory to use.

      IOException

    • setFieldName

      @Deprecated public void setFieldName(String fieldName)
      Deprecated.
      Specified by:
      setFieldName in interface ResponseProcessor<T extends Output<T>>
      Parameters:
      fieldName - The field name.

    • getOutputFactory

      public OutputFactory<T> getOutputFactory()
      Description copied from interface: ResponseProcessor
      Gets the OutputFactory this ResponseProcessor uses.
      Specified by:
      getOutputFactory in interface ResponseProcessor<T extends Output<T>>
      Returns:
      The output factory.

    • getFieldName

      @Deprecated public String getFieldName()
      Deprecated.
      Specified by:
      getFieldName in interface ResponseProcessor<T extends Output<T>>
      Returns:
      The field name.

    • process

      @Deprecated public Optional<T> process(String value)
      Deprecated.
      Specified by:
      process in interface ResponseProcessor<T extends Output<T>>
      Parameters:
      value - The value to process.
      Returns:
      The response value if found.

    • process

      public Optional<T> process(List<String> values)
      Description copied from interface: ResponseProcessor
      Returns Optional.empty() if it failed to process out a response.This method has a default implementation for backwards compatibility with Tribuo 4.0 and 4.1. This method should be overridden by code which depends on newer versions of Tribuo. The default implementation will be removed when the deprecated members are removed. Unless is is overridden it will throw an IllegalArgumentException when called with multiple values.
      Specified by:
      process in interface ResponseProcessor<T extends Output<T>>
      Parameters:
      values - The value to process.
      Returns:
      The response values if found.

    • getFieldNames

      public List<String> getFieldNames()
      Description copied from interface: ResponseProcessor
      Gets the field names this ResponseProcessor uses.
      Specified by:
      getFieldNames in interface ResponseProcessor<T extends Output<T>>
      Returns:
      The field names.

    • toString

      public String toString()
      Overrides:
      toString in class Object
