Training

For the description of the input and output, refer to Training and Prediction > Regression > Usage Model . In addition to parameters of the gradient boosted trees described in Training and Prediction > Classification and Regression > Gradient Boosted Trees > Batch Processing , the gradient boosted trees regression training algorithm has the following parameters:
Parameter
Default Value
Description
algorithmFPType
float
The floating-point type that the algorithm uses for intermediate computations. Can be
float
or
double
.
method
defaultDense
The computation method used by the gradient boosted trees regression. The only training method supported so far is the default dense method.
loss
squared
Loss function type.

Prediction

For the description of the input and output, refer to Training and Prediction > Regression > Usage Model .
In addition to the parameters of regression, the gradient boosted trees regression has the following parameters at the prediction stage:
Parameter
Default Value
Description
algorithmFPType
float
The floating-point type that the algorithm uses for intermediate computations. Can be
float
or
double
.
method
defaultDense
The computation method used by the gradient boosted trees regression. The only training method supported so far is the default dense method.
numIterations
0
An integer parameter that indicates how many trained iterations of the model should be used in prediction. The default value 0 denotes no limit. All the trained trees should be used.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
