Type Members

1.  abstract class AbstractFeatureFormatMapper[T] extends FeatureFormatMapper[T]

   Abstract base class for FeatureFormatMapper.

   Abstract base class for FeatureFormatMapper. Breaks down conversion behavior based on the various feature types.

2.  class BooleanFeatureValue extends FeatureValue

   A specific FeatureValue class for BOOLEAN features.

   A specific FeatureValue class for BOOLEAN features. Underlying representation is a boolean primitive type.

3.  class CategoricalFeatureValue extends FeatureValue

   A specific FeatureValue class for CATEGORICAL features.

   A specific FeatureValue class for CATEGORICAL features. Underlying representation is a String.

4.  class CategoricalSetFeatureValue extends FeatureValue

   A specific FeatureValue class for CATEGORICAL_SET features.

   A specific FeatureValue class for CATEGORICAL_SET features. Underlying representation is a Set of String.

5.  class DenseVectorFeatureValue extends FeatureValue

   A specific FeatureValue class for DENSE_VECTOR features.

   A specific FeatureValue class for DENSE_VECTOR features. Underlying representation is an array of float.

6.  trait FeatureFormatMapper[T] extends AnyRef

   A mapper, or translator, that can convert between the standard FeatureValue representation and some other external representation.

7.  trait FeatureValue extends AnyRef

   Represents a value of a feature in Feathr.

8.  class FeatureValues extends AnyRef

   Utility functions for constructing FeatureValue instances.

   Utility functions for constructing FeatureValue instances.

   User code that produces FeatureValues, such as Anchor extractors (in yet-to-come new Anchor extractor API), should prefer to use these when creating FeatureValues, when possible.

9.  class NTVFeatureFormatMapper extends AbstractFeatureFormatMapper[Map[String, Float]]

   A FeatureFormatMapper that converts in and out of NTV representation, using Feathr's legacy rules for representing types like NUMERIC, BOOLEAN, and DENSE_VECTOR as term vectors.

10.  class NumericFeatureValue extends FeatureValue

    A specific FeatureValue class for NUMERIC features.

    A specific FeatureValue class for NUMERIC features. Underlying representation is a float primitive value.

11.  class QuinceFeatureFormatMapper extends AbstractFeatureFormatMapper[TensorData]

    A FeatureFormatMapper that can represent any FeatureValue as a Quince TensorData.

12.  class QuinceFeatureTypeMapper extends AnyRef

    A mapper, or translator, that provides a Quince TensorType for a given FeatureType.

    A mapper, or translator, that provides a Quince TensorType for a given FeatureType.

    This class is guaranteed to conform to sister class com.linkedin.feathr.common.value.QuinceFeatureFormatMapper such that for any FeatureType-TensorType mapping provided by this class, any FeatureValue having that FeatureType would be converted to a TensorData conforming to that TensorType.

13.  class TensorFeatureValue extends FeatureValue

    A FeatureValue that contains an arbitrary tensor.

14.  class TermVectorFeatureValue extends FeatureValue

    A specific FeatureValue class for TERM_VECTOR features.

    A specific FeatureValue class for TERM_VECTOR features. Underlying representation is a Map of String to Float.
