abstract class AcceleratedGradientUtils[T] extends Serializable

Wraps necessary data strctures for accelerated gradient ascent methods.

Intializes and stores the necessary numeric data structures to calculate ascent directions. It only initializes such objects when they are called, avoiding storing unecessary arrays.

T

The structure data type, e.g., DenseVector or DenseMatrix
