Type Members

1. case class Block[T](index: Int, values: Vector[T]) extends Product with Serializable

   

   Base class for blocks of elements.

   Base class for blocks of elements.

   TODO: Replace Vector type by Array type once Flink supports generic arrays

2. case class LabeledVector(label: Double, vector: Vector) extends Serializable with Product

   

   This class represents a vector with an associated label as it is required for many supervised learning tasks.

   This class represents a vector with an associated label as it is required for many supervised learning tasks.

   label

   Label of the data point

   vector

   Data point

3. trait Parameter[T] extends AnyRef

   

   Base trait for parameter keys

   Base trait for parameter keys

   T

   Type of parameter value associated to this parameter key

4. class ParameterMap extends Serializable

   

   Map used to store configuration parameters for algorithms.

   Map used to store configuration parameters for algorithms. The parameter values are stored in a Map being identified by a Parameter object. ParameterMaps can be fused. This operation is left associative, meaning that latter ParameterMaps can override parameter values defined in a preceding ParameterMap.

5. case class WeightVector(weights: Vector, intercept: Double) extends Serializable with Product

   

   This class represents a weight vector with an intercept, as it is required for many supervised learning tasks

   This class represents a weight vector with an intercept, as it is required for many supervised learning tasks

   weights

   The vector of weights

   intercept

   The intercept (bias) weight

6. trait WithParameters extends AnyRef

   

   Adds a ParameterMap which can be used to store configuration values
