class FeatureExtractor[M[_], T] extends Serializable

Encapsulate features extracted from a FeatureSpec.
Encapsulate features extracted from a FeatureSpec.
M
input collection type, e.g. Array, List
T
input record type to extract features from
sealed trait FeatureRejection extends AnyRef
case class FeatureResult[F, T](value: F, rejections: Map[String, FeatureRejection], original: T) extends Product with Serializable
class FeatureSpec[T] extends AnyRef

Encapsulate specification for feature extraction and transformation.
Encapsulate specification for feature extraction and transformation.
T
input record type to extract features from
trait FlatReader[T] extends Serializable

TypeClass that is used to read data from flat files.
TypeClass that is used to read data from flat files. The requirement is that each feature comes from the same type and can be looked up by name.
T
The intermediate storage format for each feature.
trait FlatWriter[+T] extends Serializable

TypeClass for implementing the writer to a flat format keyed by name
trait FloatingPoint[T] extends Serializable

Type class for floating point primitives.
class MultiFeatureExtractor[M[_], T] extends Serializable

Encapsulate features extracted from a MultiFeatureSpec.
Encapsulate features extracted from a MultiFeatureSpec. Allows separation back into specs by names or vectors.
M
input collection type, e.g. Array, List
T
input record type to extract features from
class MultiFeatureSpec[T] extends AnyRef

Wrapper for FeatureSpec that allows for combination and separation of different specs.
case class NamedSparseArray[T](indices: Array[Int], values: Array[T], length: Int, names: Seq[String]) extends Product with Serializable

A SparseArray with names of non-zero entries.
class RecordExtractor[T, F] extends AnyRef

Encapsulate RecordExtractor for extracting individual records.
case class SparseArray[T](indices: Array[Int], values: Array[T], length: Int) extends Product with Serializable

A sparse representation of an array using two arrays for indices and values of non-zero entries.

object CollectionType extends Serializable
object CrossingFeatureBuilder extends Serializable
object FeatureBuilder extends Serializable
object FeatureRejection
object FeatureSpec

Companion object for FeatureSpec.
object FlatConverter extends Serializable

Companion to FlatReader.
Companion to FlatReader. Sometimes for serialization and compatability reasons it is better to write out data in an intermediate format such as JSON or tf.examples to interface with storage or other systems. This class uses the functions internal to a spec to write out the data into a new flat format.
object FlatExtractor extends Serializable

Sometimes it is useful to store the features in an intermediate state in normally a flat version like Examples or maybe JSON.
Sometimes it is useful to store the features in an intermediate state in normally a flat version like Examples or maybe JSON. This makes it easier to interface with other systems.
