BoostedTreesCenterBias

public final class BoostedTreesCenterBias

Calculates the prior from the training data (the bias) and fills in the first node with the logits' prior. Returns a boolean indicating whether to continue centering.

Constants

String OP_NAME The name of this op, as known by TensorFlow core engine

Inherited Methods

Constants

public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "BoostedTreesCenterBias"

Public Methods

public Output < TBool > asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public Output < TBool > continueCentering ()

Bool, whether to continue bias centering.

public static BoostedTreesCenterBias create ( Scope scope, Operand <?> treeEnsembleHandle, Operand < TFloat32 > meanGradients, Operand < TFloat32 > meanHessians, Operand < TFloat32 > l1, Operand < TFloat32 > l2)

Factory method to create a class wrapping a new BoostedTreesCenterBias operation.

Parameters
scope current scope
treeEnsembleHandle Handle to the tree ensemble.
meanGradients A tensor with shape=[logits_dimension] with mean of gradients for a first node.
meanHessians A tensor with shape=[logits_dimension] mean of hessians for a first node.
l1 l1 regularization factor on leaf weights, per instance based.
l2 l2 regularization factor on leaf weights, per instance based.
Returns
  • a new instance of BoostedTreesCenterBias
