Coordinate descent

This class defines a new object to conduct gradient descent in function space. Because of the component-wise structure, this is more like a block-wise coordinate descent.

Format

S4 object.

Arguments

ncores

(integer(1))
Number of cores over which the base learner fitting is distributed.

Usage

OptimizerCoordinateDescent$new()
OptimizerCoordinateDescent$new(ncores)

Fields

This class doesn't contain public fields.

Methods

• $getOptimizerType(): () -> character(1)

• $getStepSize(): () -> numeric()

Examples

# Define optimizer:
optimizer = OptimizerCoordinateDescent$new()
